ARM: driver changes for 5.19
There are minor updates to SoC specific drivers for chips by Rockchip,
Samsung, NVIDIA, TI, NXP, i.MX, Qualcomm, and Broadcom. Noteworthy
driver changes include:
- Several conversions of DT bindings to yaml format.
- Renesas adds driver support for R-Car V4H, RZ/V2M and RZ/G2UL SoCs.
- Qualcomm adds a bus driver for the SSC (Snapdragon Sensor Core),
and support for more chips in the RPMh power domains and the soc-id.
- NXP has a new driver for the HDMI blk-ctrl on i.MX8MP.
- Apple M1 gains support for the on-chip NVMe controller, making it
possible to finally use the internal disks. This also includes SoC
drivers for their RTKit IPC and for the SART DMA address filter.
For other subsystems that merge their drivers through the SoC tree,
we have
- Firmware drivers for the ARM firmware stack including TEE, OP-TEE,
SCMI and FF-A get a number of smaller updates and cleanups. OP-TEE
now has a cache for firmware argument structures as an optimization,
and SCMI now supports the 3.1 version of the specification.
- Reset controller updates to Amlogic, ASpeed, Renesas and ACPI drivers
- Memory controller updates for Tegra, and a few updates for other
platforms.

Qualcomm driver updates for v5.19
This converts a wide range of Qualcomm-related DeviceTree bindings to YAML, in order to improve our ability to validate the DeviceTree source. The RPMh power-domain driver gains support for the modem platform SDX65, the compute platform SC8280XP and the automotive platform SA8540p. While LLCC gains support for SC8180X and SC8280XP and gains a MODULE_DEVICE_TABLE() to make it functional as a module. It adds a driver for configuring the SSC bus, providing Linux access to the hardware blocks in the sensor subsystem. The socinfo driver gets confusion related to MSM8974 Pro sorted out and adds new ids for SM8540 and SC7280. The SCM driver gains support for MSM8974. Add missing of_node_put() in smp2p and smsm drivers. Stop using iterator after list_for_each_entry() and define static definitions as such, in the PDR driver. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmJ5WsYbHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3FIo8P+wcc78TQQuG67nqPr2gb QFqVK8U2mz07XW0H1rnGZKsTSrZxFs/YWRBaw+dYC5OZVJHx/uoZM04Njsyy/DFh UaNQgTgsS4+D5+butveh4lBdmk4ja5sreLHw25/azw5VBzeHb9+4HeAd7QMMQ+BO /EvIlykPwsgGIZwabzDHkY8w/xt64CPiajps1qGlFDJedSLsdJ8bKHctvcFD03v3 3utJku3jAc5SZMBQgDttpPwpn7UnHXjCvWxyz8oSFaWDQBROztH0FbiJsZnjMuFI 9RfRqblgb2PkvaG23W7jv68aJf3yQ6siY8ezPPs3/1F6T6tMQaAKEhwrY93ZQiWc gDDx33TvX3YJiRRdC2Gvg1QpL4xMFUERR8o4ooQ0t+b8bG6TkGP44VVg3/n1wrMK Q5xdgDigfrNnVZV1b2flQHc4qke4hNoV23SQ7iFWvtSJO09xklVJhXFGQ6mthEkb PnBFurLyxglKw6afs1/2P8tplS52K0l19lgNJu6vtUzC6fMOg50cX0mmWP8+rkFb njhXlPqCDataECZazyxnn7KORAn3E7zQceJ/LJeV+XZ9i5DJLXup+JkuBCWem4Nd ucEeYtQVRel5FCWZZzkXviPCTlWgTB7ya7pJPCzvZpnNFHeSWSjr9YK6xtWwy9rP CBRXYrz2gJLV/MGkB1piAwkm =/Dqp -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmJ5hB4ACgkQmmx57+YA GNksBxAAj09+d2U1sFSJl3HiHTrXyg3MYoG0dA1QK2CRKucdwMf6KBGpEHTQyL6a Iqan6URrTqEM3WP4suBsZh8vbv1C8u7KGWwDAMqJ18BkigoGHEV1PyvmHYRvPoT2 6DSHAkGbYfDglxXZ4JcxNaQk3+t6rZpe5LcRRgQ7JpoKfzlqKxfSJfPFLzYAvhSV qThiyd3GvfcgkVHL9noh4BrBrnNRj7wMzUwQnhW5aWebN+DqgG8zlzmmZEQx61uR sjMogRZNpGXVAR+4yvPZNoxTGM0plssxlkDQGS4b0XLP1t7ohr22eFPTrWqcsYCi h4fa3nXxUIoTDJXQ7nmU04VXp5xVUtQKKe+zXIvQBT98OkM1f6ep5i7rrEh5DZxJ TWVdRLuIVpHVsVARqq+qpEnwyDeiF3Hgmope3xPYhEIs1WcIOQzWBjHbNTNeiFdy fQMrmAQjirXJBV18ImRSMcAXW+Shc72vnj6fViQcrL5Pzj1HJFMjh/bpPzAhIUYJ w9to8mpNgHUpMwnkfMUqQDV6FANVbYPqancK/z4rEPd8mj6bq1z2GEQq2e9+cAfM imyD30+g7fm7e4mxp53mv/oxqf4NJExE0eIjXAQY53at0TCk+ngsxJd96Wz3aIpB eL9YN5x+y6vXkFC+hsnX2/QdUiVCmfpbrez2QqzoZncSkJ4mjdI= =rjVH -----END PGP SIGNATURE----- Merge tag 'qcom-drivers-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers Qualcomm driver updates for v5.19 This converts a wide range of Qualcomm-related DeviceTree bindings to YAML, in order to improve our ability to validate the DeviceTree source.

bus: platform,amba,fsl-mc,PCI: Add device DMA ownership management
The devices on platform/amba/fsl-mc/PCI buses could be bound to drivers
with the device DMA managed by kernel drivers or user-space applications.
Unfortunately, multiple devices may be placed in the same IOMMU group
because they cannot be isolated from each other. The DMA on these devices
must either be entirely under kernel control or userspace control, never
a mixture. Otherwise the driver integrity is not guaranteed because they
could access each other through the peer-to-peer accesses which by-pass
the IOMMU protection.
This checks and sets the default DMA mode during driver binding, and
cleanups during driver unbinding. In the default mode, the device DMA is
managed by the device driver which handles DMA operations through the
kernel DMA APIs (see Documentation/core-api/dma-api.rst).
For cases where the devices are assigned for userspace control through the
userspace driver framework(i.e. VFIO), the drivers(for example, vfio_pci/
vfio_platfrom etc.) may set a new flag (driver_managed_dma) to skip this
default setting in the assumption that the drivers know what they are
doing with the device DMA.
Calling iommu_device_use_default_domain() before {of,acpi}_dma_configure
is currently a problem. As things stand, the IOMMU driver ignored the
initial iommu_probe_device() call when the device was added, since at
that point it had no fwspec yet. In this situation,
{of,acpi}_iommu_configure() are retriggering iommu_probe_device() after
the IOMMU driver has seen the firmware data via .of_xlate to learn that
it actually responsible for the given device. As the result, before
that gets fixed, iommu_use_default_domain() goes at the end, and calls
arch_teardown_dma_ops() if it fails.

bus: sunxi-rsb: Fix the return value of sunxi_rsb_device_create()
This code is really spurious.
It always returns an ERR_PTR, even when err is known to be 0 and calls
put_device() after a successful device_register() call.
It is likely that the return statement in the normal path is missing.
Add 'return rdev;' to fix it.

bus: add driver for initializing the SSC bus on (some) qcom SoCs
Add bindings for the AHB bus which exposes the SSC (Snapdragon Sensor Core) block in the global address space. This bus (and the SSC block itself) is present on certain qcom SoCs. In typical configuration, this bus (as some of the clocks and registers that we need to manipulate) is not accessible to Linux, and the resources on this bus are indirectly accessed by communicating with a hexagon CPU core residing in the SSC block. In this configuration, the hypervisor is the one performing the bus initialization for the purposes of bringing the hexagon CPU core out of reset. However, it is possible to change the configuration, in which case this driver will initialize the bus. In combination with drivers for resources on the SSC bus, this driver can aid in debugging, and for example with a TLMM driver can be used to directly access SSC-dedicated GPIO pins, removing the need to commit to a particular usecase during hw design. Finally, until open firmware for the hexagon core is available, this approach allows for using sensors hooked up to SSC-dedicated GPIO pins on mainline Linux simply by utilizing the existing in-tree drivers for these sensors.

bus: mhi: host: pci_generic: Flush recovery worker during freeze
It is possible that the recovery work might be running while the freeze
gets executed (during hibernation etc.,). Currently, we don't powerdown
the stack if it is not up but if the recovery work completes after freeze,
then the device will be up afterwards. This will not be a sane situation.
So let's flush the recovery worker before trying to powerdown the device.

bus: mhi: host: pci_generic: Add missing poweroff() PM callback
During hibernation process, once thaw() stage completes, the MHI endpoint
devices will be in M0 state post recovery. After that, the devices will be
powered down so that the system can enter the target sleep state. During
this stage, the PCI core will put the devices in D3hot. But this transition
is allowed by the MHI spec. The devices can only enter D3hot when it is in
M3 state.
So for fixing this issue, let's add the poweroff() callback that will get
executed before putting the system in target sleep state during
hibernation. This callback will power down the device properly so that it
could be restored during restore() or thaw() stage.

bus: ti-sysc: Make omap3 gpt12 quirk handling SoC specific
On beagleboard revisions A to B4 we need to use gpt12 as the system timer.
However, the quirk handling added for gpt12 caused a regression for system
suspend for am335x as the PM coprocessor needs the timers idled for
suspend.
Let's make the gpt12 quirk specific to omap34xx, other SoCs don't need
it. Beagleboard revisions C and later no longer need to use the gpt12
related quirk. Then at some point, if we decide to drop support for the old
beagleboard revisions A to B4, we can also drop the gpt12 related quirks
completely.

ARM driver updates for 5.18
There are a few separately maintained driver subsystems that we merge through
the SoC tree, notable changes are:
- Memory controller updates, mainly for Tegra and Mediatek SoCs,
and clarifications for the memory controller DT bindings
- SCMI firmware interface updates, in particular a new transport based
on OPTEE and support for atomic operations.
- Cleanups to the TEE subsystem, refactoring its memory management
For SoC specific drivers without a separate subsystem, changes include
- Smaller updates and fixes for TI, AT91/SAMA5, Qualcomm and NXP
Layerscape SoCs.
- Driver support for Microchip SAMA5D29, Tesla FSD, Renesas RZ/G2L,
and Qualcomm SM8450.
- Better power management on Mediatek MT81xx, NXP i.MX8MQ
and older NVIDIA Tegra chips

spi: Updates for v5.18
The overwhelming bulk of this pull request is a change from Uwe
Kleine-König which changes the return type of the remove() function to
void as part of some wider work he's doing to do this for all bus types,
causing updates to most SPI device drivers. The branch with that on has
been cross merged with a couple of other trees which added new SPI
drivers this cycle, I'm not expecting any build issues resulting from
the change.
Otherwise it's been a relatively quiet release with some new device
support, a few minor features and the welcome completion of the
conversion of the subsystem to use GPIO descriptors rather than numbers:
- Change return type of remove() to void.
- Completion of the conversion of SPI controller drivers to use GPIO
descriptors rather than numbers.
- Quite a few DT schema conversions.
- Support for multiple SPI devices on a bus in ACPI systems.
- Big overhaul of the PXA2xx SPI driver.
- Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and
Sunplus SP7021.

bus: mhi: Use bitfield operations for register read and write
Functions like mhi_read_reg_field(), mhi_poll_reg_field() and mhi_write_reg_field() could be modified to not depend on the shift value passed as an argument. Instead, the bitfield operation could be used to extract the shift value from the mask itself. This eliminates the need to define _SHIFT (and _SHFT) macros and simplifies the code a bit. For shift values those cannot be determined during build time, "__ffs()" helper is used find the shift value during runtime. While at it, let's also get rid of 32-bit masks like CHDBOFF_CHDBOFF_MASK by doing the full 32-bit register read.

bus: mhi: Fix MHI DMA structure endianness
The MHI driver does not work on big endian architectures. The controller never transitions into mission mode. This appears to be due to the modem device expecting the various contexts and transfer rings to have fields in little endian order in memory, but the driver constructs them in native endianness. Fix MHI event, channel and command contexts and TRE handling macros to use explicit conversion to little endian. Mark fields in relevant structures as little endian to document this requirement.

bus: mhi: Fix pm_state conversion to string
On big endian architectures the mhi debugfs files which report pm state
give "Invalid State" for all states. This is caused by using
find_last_bit which takes an unsigned long* while the state is passed in
as an enum mhi_pm_state which will be of int size.
Fix by using __fls to pass the value of state instead of find_last_bit.
Also the current API expects "mhi_pm_state" enumerator as the function
argument but the function only works with bitmasks. So as Alex suggested,
let's change the argument to u32 to avoid confusion.

spi: make remove callback a void function
The value returned by an spi driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

bus: mhi: core: Use correctly sized arguments for bit field
The find.h APIs are designed to be used only on unsigned long arguments.
This can technically result in a over-read, but it is harmless in this
case. Regardless, fix it to avoid the warning seen under -Warray-bounds,
which we'd like to enable globally:

bus: mhi: core: Add an API for auto queueing buffers for DL channel
Add a new API "mhi_prepare_for_transfer_autoqueue" for using with client drivers like QRTR to request MHI core to autoqueue buffers for the DL channel along with starting both UL and DL channels. So far, the "auto_queue" flag specified by the controller drivers in channel definition served this purpose but this will be removed at some point in future.
