Pull libnvdimm updayes from Vishal Verma:
"You'd normally receive this pull request from Dan Williams, but he's
busy watching a newborn (Congrats Dan!), so I'm watching libnvdimm
this cycle.
This adds a new feature in libnvdimm - 'Runtime Firmware Activation',
and a few small cleanups and fixes in libnvdimm and DAX. I'd
originally intended to make separate topic-based pull requests - one
for libnvdimm, and one for DAX, but some of the DAX material fell out
since it wasn't quite ready.
Summary:
- add 'Runtime Firmware Activation' support for NVDIMMs that
advertise the relevant capability
- misc libnvdimm and DAX cleanups"

f2fs-for-5.9-rc1
In this round, we've added two small interfaces, 1) GC_URGENT_LOW mode for performance, and 2) F2FS_IOC_SEC_TRIM_FILE ioctl for security. The new GC mode allows Android to run some lower priority GCs in background, while new ioctl discards user information without race condition when the account is removed. In addition, some patches were merged to address latency-related issues. We've fixed some compression-related bug fixes as well as edge race conditions. Enhancement: - add GC_URGENT_LOW mode in gc_urgent - introduce F2FS_IOC_SEC_TRIM_FILE ioctl - bypass racy readahead to improve read latencies - shrink node_write lock coverage to avoid long latency Bug fix: - fix missing compression flag control, i_size, and mount option - fix deadlock between quota writes and checkpoint - remove inode eviction path in synchronous path to avoid deadlock - fix to wait GCed compressed page writeback - fix a kernel panic in f2fs_is_compressed_page - check page dirty status before writeback - wait page writeback before update in node page write flow - fix a race condition between f2fs_write_end_io and f2fs_del_fsync_node_entry We've added some minor sanity checks and refactored trivial code blocks for better readability and debugging information. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAl8xhqMACgkQQBSofoJI UNLYgA//WMoOqBACDuOWwYmgQ8oq4vrH2LOwssZF9/77vEfaHKc+TSq1il54lcUl MPEx7FK54CnfT8VLLR5ByobZFyH9FFeAw4FN4LBhcfE8jh8ysAGjeoZjwfcmJF6R cVKtn8ltUpgH3IEUuPjTiKkVNHfVJxuuL3zHbg1CEl+AkR6NJ/U9kNLwf7ZgPWq2 I0qwyXRlUIEChhyPZB+Y6RsdGjkeievKld56DMCgG73f4yHRO/yBcrfsN875sGdM ALL+mYiunMT6aXcfoiQiAjeImoNajuflI6Zso2Sk8Vl6sBj0QwAuEBF5x1Z5e1mt YVYNuC4ucqsDBKpOqtsPP0MFTC2T5Rr9wWXjqv+9TjN7zvJ8xx+zDWtQxvI2bpqB 4ZRxaJP45aThLYh/SEYDmj+ppyPtfLDeG0HzUkwMmuopf9eg+kxGPjBsZewgkCKg kmMKU0P7deGlkrWLUcz2vm0Lso+ieGm0IeLOQl9/rOLu3IQQFia0Vla7dLDgqF0P sz+udIiBztC3JPEmEZhfayA6P6e1TyWQUdquL08jp+DZD17gPqcaZDhHr62U5rmK 7zoiZqkR03SbNaFhBhhoVOaAVcAnF0pSIgqzkCa3dVXxp1QV+JfD9CGR9NFyiIqB HK5RPFskIUCg0K2LSaAKbyoFWa/fJ8ZD8/CbFWcnXfWzoaaSkmc= =PjaF -----END PGP SIGNATURE----- Merge tag 'f2fs-for-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've added two small interfaces: (a) GC_URGENT_LOW mode for performance and (b) F2FS_IOC_SEC_TRIM_FILE ioctl for security.

powerpc updates for 5.9
- Add support for (optionally) using queued spinlocks & rwlocks.
- Support for a new faster system call ABI using the scv instruction on Power9
or later.
- Drop support for the PROT_SAO mmap/mprotect flag as it will be unsupported on
Power10 and future processors, leaving us with no way to implement the
functionality it requests. This risks breaking userspace, though we believe
it is unused in practice.
- A bug fix for, and then the removal of, our custom stack expansion checking.
We now allow stack expansion up to the rlimit, like other architectures.
- Remove the remnants of our (previously disabled) topology update code, which
tried to react to NUMA layout changes on virtualised systems, but was prone
to crashes and other problems.
- Add PMU support for Power10 CPUs.
- A change to our signal trampoline so that we don't unbalance the link stack
(branch return predictor) in the signal delivery path.
- Lots of other cleanups, refactorings, smaller features and so on as usual.

Input: exc3000 - add support to query model and fw_version
Expose model and fw_version via sysfs. Also query the model in probe to make sure, that the I2C communication with the device works before successfully probing the driver. This is a bit complicated, since EETI devices do not have a sync interface. Sending the commands and directly reading does not work. Sending the command and waiting for some time is also not an option, since there might be touch events in the mean time. Last but not least we do not cache the results, since this interface can be used to check the I2C communication is still working as expected.

We also have a huge docbook fix update like most other subsystems and no major update to the core (the few non trivial updates are either minor fixes or removing an unused feature [scsi_sdb_cache]).

Staging/IIO driver patches for 5.9-rc1
Here is the large set of Staging and IIO driver patches for 5.9-rc1. Lots of churn here, but overall the size increase in lines added is small, while adding a load of new IIO drivers. Major things in here: - lots and lots of IIO new drivers and frameworks added - IIO driver fixes and updates - lots of tiny coding style cleanups for staging drivers - vc04_services major reworks and cleanups We had 3 set of drivers move out of staging in this round as well: - wilc1000 wireless driver moved out of staging - speakup moved out of staging - most USB driver moved out of staging Full details are in the shortlog. All of these have been in linux-next with no reported issues. The last few changes here were to resolve reported linux-next issues, and they seem to have resolved the problems.

LEDs changes for 5.9-rc1.
Okay, so... this one is interesting. RGB LEDs are very common, and we need to have some kind of support for them. Multicolor is for arbitrary set of LEDs in one package, RGB is for LEDs that can produce full range of colors. We do not have real multicolor LED that is not RGB in the pipeline, so that one is disabled for now. You can expect this saga to continue with next pull requests. -----BEGIN PGP SIGNATURE----- iF0EABECAB0WIQRPfPO7r0eAhk010v0w5/Bqldv68gUCXyskqQAKCRAw5/Bqldv6 8ge0AJ9JRTa/0Xkl7JuKUpC93jAnvjpK+ACgsDijb77H5zmtwC8xa0kXiDsbh3E= =aSJX -----END PGP SIGNATURE----- Merge tag 'leds-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/pavel/linux-leds Pull LED updates from Pavel Machek: "Okay, so... this one is interesting.

Driver core changes for 5.9-rc1
Here is the "big" set of changes to the driver core, and some drivers
using the changes, for 5.9-rc1.
"Biggest" thing in here is the device link exposure in sysfs, to help
to tame the madness that is SoC device tree representations and driver
interactions with it.
Other stuff in here that is interesting is:
- device probe log helper so that drivers can report problems in
a unified way easier.
- devres functions added
- DEVICE_ATTR_ADMIN_* macro added to make it harder to write
incorrect sysfs file permissions
- documentation cleanups
- ability for debugfs to be present in the kernel, yet not
exposed to userspace. Needed for systems that want it
enabled, but do not trust users, so they can still use some
kernel functions that were otherwise disabled.
- other minor fixes and cleanups
The patches outside of drivers/base/ all have acks from the respective
subsystem maintainers to go through this tree instead of theirs.
All of these have been in linux-next with no reported issues.

It's been a busy cycle for documentation - hopefully the busiest for a
while to come. Changes include:
- Some new Chinese translations
- Progress on the battle against double words words and non-HTTPS URLs
- Some block-mq documentation
- More RST conversions from Mauro. At this point, that task is
essentially complete, so we shouldn't see this kind of churn again for a
while. Unless we decide to switch to asciidoc or something...:)
- Lots of typo fixes, warning fixes, and more.

Pull power management updates from Rafael Wysocki:
"The most significant change here is the extension of the Energy Model
to cover non-CPU devices (as well as CPUs) from Lukasz Luba.
There is also some new hardware support (Ice Lake server idle states
table for intel_idle, Sapphire Rapids and Power Limit 4 support in the
RAPL driver), some new functionality in the existing drivers (eg. a
new switch to disable/enable CPU energy-efficiency optimizations in
intel_pstate, delayed timers in devfreq), some assorted fixes (cpufreq
core, intel_pstate, intel_idle) and cleanups (eg. cpuidle-psci,
devfreq), including the elimination of W=1 build warnings from cpufreq
done by Lee Jones.
Specifics:
- Make the Energy Model cover non-CPU devices (Lukasz Luba).

ARM: SoC driver updates for v5.9
A couple of subsystems have their own subsystem maintainers but choose
to have the code merged through the soc tree as upstream, as the code
tends to be used across multiple SoCs or has SoC specific drivers itself:
- memory controllers:
Krzysztof Kozlowski takes ownership of the drivers/memory
subsystem and its drivers, starting out with a set of cleanup
patches.
A larger driver for the Tegra memory controller that was accidentally
missed for v5.8 is now added.
- reset controllers:
Only minor updates to drivers/reset this time
- firmware:
The "turris mox" firmware driver gains support for signed firmware blobs
The tegra firmware driver gets extended to export some debug information
Various updates to i.MX firmware drivers, mostly cosmetic
- ARM SCMI/SCPI:
A new mechanism for platform notifications is added, among a number
of minor changes.
- optee:
Probing of the TEE bus is rewritten to better support detection of
devices that depend on the tee-supplicant user space.
A new firmware based trusted platform module (fTPM) driver is added
based on OP-TEE
- SoC attributes:
A new driver is added to provide a generic soc_device for identifying
a machine through the SMCCC ARCH_SOC_ID firmware interface rather than
by probing SoC family specific registers.
The series also contains some cleanups to the common soc_device code.
There are also a number of updates to SoC specific drivers,
the main ones are:
- Mediatek cmdq driver gains a few in-kernel interfaces
- Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding
support for additional SoC variants
- The Qualcomm GENI core code gains interconnect path voting and
performance level support, and integrating this into a number of
device drivers.
- A new driver for Samsung Exynos5800 voltage coupler for
- Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC
specific device drivers
- Updates to the TI K3 Ring Accelerator driver

powerpc/papr_scm: Fetch nvdimm performance stats from PHYP
Update papr_scm.c to query dimm performance statistics from PHYP via H_SCM_PERFORMANCE_STATS hcall and export them to user-space as PAPR specific NVDIMM attribute 'perf_stats' in sysfs. The patch also provide a sysfs ABI documentation for the stats being reported and their meanings. During NVDIMM probe time in papr_scm_nvdimm_init() a special variant of H_SCM_PERFORMANCE_STATS hcall is issued to check if collection of performance statistics is supported or not. If successful then a PHYP returns a maximum possible buffer length needed to read all performance stats. This returned value is stored in a per-nvdimm attribute 'stat_buffer_len'. The layout of request buffer for reading NVDIMM performance stats from PHYP is defined in 'struct papr_scm_perf_stats' and 'struct papr_scm_perf_stat'. These structs are used in newly introduced drc_pmem_query_stats() that issues the H_SCM_PERFORMANCE_STATS hcall. The sysfs access function perf_stats_show() uses value 'stat_buffer_len' to allocate a buffer large enough to hold all possible NVDIMM performance stats and passes it to drc_pmem_query_stats() to populate. Finally statistics reported in the buffer are formatted into the sysfs access function output buffer.

power: supply: wilco_ec: Add long life charging mode
This is a long life mode set in the factory for extended warranty battery, the power charging rate is customized so that battery at work last longer. Presently switching to a different battery charging mode is through EC PID 0x0710 to configure the battery firmware, this operation will be blocked by EC with failure code 0x01 when PLL mode is already in use.

PM / devfreq: Add support delayed timer for polling mode
Until now, the devfreq driver using polling mode like simple_ondemand governor have used only deferrable timer for reducing the redundant power consumption. It reduces the CPU wake-up from idle due to polling mode which check the status of Non-CPU device. But, it has a problem for Non-CPU device like DMC device with DMA operation. Some Non-CPU device need to do monitor continuously regardless of CPU state in order to decide the proper next status of Non-CPU device. So, add support the delayed timer for polling mode to support the repetitive monitoring. The devfreq driver and user can select the kind of timer on either deferrable and delayed timer. For example, change the timer type of DMC device based on Exynos5422-based Odroid-XU3 as following: - If want to use deferrable timer as following: echo deferrable > /sys/class/devfreq/10c20000.memory-controller/timer - If want to use delayed timer as following: echo delayed > /sys/class/devfreq/10c20000.memory-controller/timer Reviewed-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Reviewed-by: Lukasz Luba <lukasz.luba@arm.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> |

mei: add device kind to sysfs
Some of the mei device heads are not generic and have a specific purpose, we need to announce it to the user space so it is possible to detect the correct device node via matching attributes. Generic heads are marked as 'mei' while special purpose heads have their own names. Currently we are adding 'itouch' string for Intel IPTS 1.0, 2.0 devices. This is done via new sysfs attribute 'kind'.

ACPI: NFIT: Add runtime firmware activate support
Plumb the platform specific backend for the generic libnvdimm firmware activate interface. Register dimm level operations to arm/disarm activation, and register bus level operations to report the dynamic platform-quiesce time relative to the number of dimms armed for firmware activation. A new nfit-specific bus attribute "firmware_activate_noidle" is added to allow the activation to switch between platform enforced, and OS opportunistic device quiesce. In other words, let the hibernate cycle handle in-flight device-dma rather than the platform attempting to increase PCI-E timeouts and the like.

PM, libnvdimm: Add runtime firmware activation support
Abstract platform specific mechanics for nvdimm firmware activation behind a handful of generic ops. At the bus level ->activate_state() indicates the unified state (idle, busy, armed) of all DIMMs on the bus, and ->capability() indicates the system state expectations for activate. At the DIMM level ->activate_state() indicates the per-DIMM state, ->activate_result() indicates the outcome of the last activation attempt, and ->arm() attempts to transition the DIMM from 'idle' to 'armed'. A new hibernate_quiet_exec() facility is added to support firmware activation in an OS defined system quiesce state. It leverages the fact that the hibernate-freeze state wants to assert that a memory hibernation snapshot can be taken. This is in contrast to a platform firmware defined quiesce state that may forcefully quiet the memory controller independent of whether an individual device-driver properly supports hibernate-freeze. The libnvdimm sysfs interface is extended to support detection of a firmware activate capability. The mechanism supports enumeration and triggering of firmware activate, optionally in the hibernate_quiet_exec() context.

First set of new device support, cleanups and features for IIO in the 5.9 cycle
Some new devices, but particularly good this time is the core rework coming
from Alexandru. Some of this has been in Analog's tree a long time, but other
parts are motivated by closing down common mistakes in new drivers.
Changes since first try at this pull request:
* Add missed patch to actually remove iio_priv_to_dev and as a result
also drop a few ingenic patches that need to be updated to take this
into account.
* Fix an ordering issue int he pollfunc attach in the core rework.
New device support
* qcom pmic7 adc
- New driver using common qcom-vadc library. Some associated cleanups and
refactors.
* invensense icm42600
- New driver supporting icm42600, icm42602, icm42605 and icm42622 via i2c
or spi. These are all 6 axis IMUs with gyro and accelerometers.
Driver supports buffered modes using the hardware fifo and interpolation
for accurate timestamps.
* sensirion scd30
- New driver for this carbon dioxide sensor including i2c and serial
interfaces + bindings.
Features
* ak8975
- Add reset gpio support.
* bma400
- Support SPI.
* bmc150
- Document and add support for bmc156b and bmm150b, tidy up _magn endings.
* bmi160
- Regulator and mount matrix support.
* mxc4005
- Add ID for mxc6655
* rockchip-saradc
- Triggered buffer support.
DT bindings
* qcom spmi-vadc converted to yaml + pmic7 bindings
* ak8975 tidy up and convert to yaml + add reset-gpio binding
* ingenic-adc -convert to yaml.
Core rework all carried through by Alexandru Ardelean.
* Assign parent device in the core rather than every driver. A few devices
need to provide specific non standard parents, so there is support for
overriding.
* Start to take parts of struct iio_dev opaque to the drivers.
This will be a long term job, but should reduce the number of drivers
we get that use parts that are currently only 'internal' by documentation.
* Move attach and detach of pollfunc to the core. Every triggered buffer
using driver had to do the same thing, so lets do it in the core. The
hard part here was getting all the drivers into canonical form so there
would be no functional changes in this final patch. That's taken quite
a lot of work over last couple of cycles!
Cleanups and minor fixes.
* docs
- Improve IIO_CONCENTRATION channel type description in ABI docs.
- Drop doubled word cases.
- Http to Https conversion.
* core
- Make iio_device_get_drvdata take a const struct iio_dev * avoiding some
nasty casts.
* ADCs
- Drop lots of users of of_match_ptr macro, includes of mod_devicetable.h
and CONFIG_OF protections. These prevent use of ACPI PRP0001 with these
drivers and get coppied into lots of new drivers.
* ad5380
- Constify iio_chan_spec_ext_info
* ad5592r
- Constify iio_chan_spec_ext_info
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* ad8366
- Make gpio optional as doesn't matter if its there or not.
* adis16480
- Use irq types instead of the flags.
* atlas-ezo-sensor
- Minimize scope of ret variable.
* at91-adc
- Add COMPILE_TEST dependency to driver to improve build coverage.
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* at91-sama5d2
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
- Drop Ludovic as a co-maintaienr.
* cros_ec
- Reapply the range after resume.
- Add a read only frequency entry for legacy version.
- Typo fixes
* hts221
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* inv_mpu
- Drop double check on ACPI companion device.
* iqs621
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* iqs624
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* max11100
- Constify iio_chan_spec
* mmc35240
- Constify reg_default
* rockchip-saradc
- Move to managed allocators for everything in probe.
- Use more distinctive prefix for channel macros.
* stk3310
- Constify regmap_config.
* stm32-adc
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* stm32-dfsdm-adc
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* ti-am335x
- Use managed allocations where straight forward in probe function.

Merge tag 'iio-for-5.9a-take2' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
First set of new device support, cleanups and features for IIO in the 5.9 cycle
Some new devices, but particularly good this time is the core rework coming
from Alexandru. Some of this has been in Analog's tree a long time, but other
parts are motivated by closing down common mistakes in new drivers.
Changes since first try at this pull request:
* Add missed patch to actually remove iio_priv_to_dev and as a result
also drop a few ingenic patches that need to be updated to take this
into account.
* Fix an ordering issue int he pollfunc attach in the core rework.
New device support
* qcom pmic7 adc
- New driver using common qcom-vadc library. Some associated cleanups and
refactors.
* invensense icm42600
- New driver supporting icm42600, icm42602, icm42605 and icm42622 via i2c
or spi. These are all 6 axis IMUs with gyro and accelerometers.
Driver supports buffered modes using the hardware fifo and interpolation
for accurate timestamps.
* sensirion scd30
- New driver for this carbon dioxide sensor including i2c and serial
interfaces + bindings.
Features
* ak8975
- Add reset gpio support.
* bma400
- Support SPI.
* bmc150
- Document and add support for bmc156b and bmm150b, tidy up _magn endings.
* bmi160
- Regulator and mount matrix support.
* mxc4005
- Add ID for mxc6655
* rockchip-saradc
- Triggered buffer support.
DT bindings
* qcom spmi-vadc converted to yaml + pmic7 bindings
* ak8975 tidy up and convert to yaml + add reset-gpio binding
* ingenic-adc -convert to yaml.
Core rework all carried through by Alexandru Ardelean.
* Assign parent device in the core rather than every driver. A few devices
need to provide specific non standard parents, so there is support for
overriding.
* Start to take parts of struct iio_dev opaque to the drivers.
This will be a long term job, but should reduce the number of drivers
we get that use parts that are currently only 'internal' by documentation.
* Move attach and detach of pollfunc to the core. Every triggered buffer
using driver had to do the same thing, so lets do it in the core. The
hard part here was getting all the drivers into canonical form so there
would be no functional changes in this final patch. That's taken quite
a lot of work over last couple of cycles!
Cleanups and minor fixes.
* docs
- Improve IIO_CONCENTRATION channel type description in ABI docs.
- Drop doubled word cases.
- Http to Https conversion.
* core
- Make iio_device_get_drvdata take a const struct iio_dev * avoiding some
nasty casts.
* ADCs
- Drop lots of users of of_match_ptr macro, includes of mod_devicetable.h
and CONFIG_OF protections. These prevent use of ACPI PRP0001 with these
drivers and get coppied into lots of new drivers.
* ad5380
- Constify iio_chan_spec_ext_info
* ad5592r
- Constify iio_chan_spec_ext_info
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* ad8366
- Make gpio optional as doesn't matter if its there or not.
* adis16480
- Use irq types instead of the flags.
* atlas-ezo-sensor
- Minimize scope of ret variable.
* at91-adc
- Add COMPILE_TEST dependency to driver to improve build coverage.
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* at91-sama5d2
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
- Drop Ludovic as a co-maintaienr.
* cros_ec
- Reapply the range after resume.
- Add a read only frequency entry for legacy version.
- Typo fixes
* hts221
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* inv_mpu
- Drop double check on ACPI companion device.
* iqs621
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* iqs624
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)

powerpc/hv-24x7: Add sysfs files inside hv-24x7 device to show cpumask
Patch here adds a cpumask attr to hv_24x7 pmu along with ABI documentation. Primary use to expose the cpumask is for the perf tool which has the capability to parse the driver sysfs folder and understand the cpumask file. Having cpumask file will reduce the number of perf command line parameters (will avoid "-C" option in the perf tool command line). It can also notify the user which is the current cpu used to retrieve the counter data. command:# cat /sys/devices/hv_24x7/interface/cpumask 0 Signed-off-by: Kajol Jain <kjain@linux.ibm.com> Reviewed-by: Madhavan Srinivasan <maddy@linux.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/20200709051836.723765-3-kjain@linux.ibm.com |

block: add max_active_zones to blk-sysfs
Add a new max_active zones definition in the sysfs documentation. This definition will be common for all devices utilizing the zoned block device support in the kernel. Export max_active_zones according to this new definition for NVMe Zoned Namespace devices, ZAC ATA devices (which are treated as SCSI devices by the kernel), and ZBC SCSI devices. Add the new max_active_zones member to struct request_queue, rather than as a queue limit, since this property cannot be split across stacking drivers. For SCSI devices, even though max active zones is not part of the ZBC/ZAC spec, export max_active_zones as 0, signifying "no limit".

habanalabs: set clock gating per engine
For debugging purposes, we need to allow the root user better control of the clock gating feature of the DMA and compute engines. Therefore, change the clock gating debugfs interface to be bitmask instead of true/false. Each bit represents a different engine, according to gaudi_engine_id enum. See debugfs documentation for more details. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com> Reviewed-by: Omer Shpigelman <oshpigelman@habana.ai> |

driver core: Add waiting_for_supplier sysfs file for devices
This would be useful to check if a device is not probing because it's waiting for a supplier to be added and then linked to before it can probe. To reduce sysfs clutter, this file is added only if it can ever be 1. So, if fw_devlink is disabled or set to permissive, this file is not added. Also, this file is removed once the device probes as it's no longer relevant.
