tee: amdtee: Add return_origin to 'struct tee_cmd_load_ta'
After TEE has completed processing of TEE_CMD_ID_LOAD_TA, set proper
value in 'return_origin' argument passed by open_session() call. To do
so, add 'return_origin' field to the structure tee_cmd_load_ta. The
Trusted OS shall update return_origin as part of TEE processing.
This change to 'struct tee_cmd_load_ta' interface requires a similar update
in AMD-TEE Trusted OS's TEE_CMD_ID_LOAD_TA interface.
This patch has been verified on Phoenix Birman setup. On older APUs,
return_origin value will be 0.

Driver core changes for 6.4-rc1
Here is the large set of driver core changes for 6.4-rc1. Once again, a busy development cycle, with lots of changes happening in the driver core in the quest to be able to move "struct bus" and "struct class" into read-only memory, a task now complete with these changes. This will make the future rust interactions with the driver core more "provably correct" as well as providing more obvious lifetime rules for all busses and classes in the kernel. The changes required for this did touch many individual classes and busses as many callbacks were changed to take const * parameters instead. All of these changes have been submitted to the various subsystem maintainers, giving them plenty of time to review, and most of them actually did so. Other than those changes, included in here are a small set of other things: - kobject logging improvements - cacheinfo improvements and updates - obligatory fw_devlink updates and fixes - documentation updates - device property cleanups and const * changes - firwmare loader dependency fixes. All of these have been in linux-next for a while with no reported problems.

ARM: SoC drivers for v6.4
The most notable updates this time are for Qualcomm Snapdragon platforms.
The Inline-Crypto-Engine gets a new DT binding and driver. A number of
drivers now support additional Snapdragon variants, in particular the
rsc, scm, geni, bwm, glink and socinfo, while the llcc (edac) and rpm
drivers get notable functionality updates.
Updates on other platforms include:
- Various updates to the Mediatek mutex and mmsys drivers, including
support for the Helio X10 SoC
- Support for unidirectional mailbox channels in Arm SCMI firmware
- Support for per cpu asynchronous notification in OP-TEE firmware
- Minor updates for memory controller drivers.
- Minor updates for Renesas, TI, Amlogic, Apple, Broadcom, Tegra,
Allwinner, Versatile Express, Canaan, Microchip, Mediatek and i.MX
SoC drivers, mainly updating the use of MODULE_LICENSE() macros and
obsolete DT driver interfaces.

optee: fix uninited async notif value
Fixes an uninitialized variable in irq_handler() that could lead to
unpredictable behavior in case OP-TEE fails to handle SMC function ID
OPTEE_SMC_GET_ASYNC_NOTIF_VALUE. This change ensures that in that case
get_async_notif_value() properly reports there are no notification
event.

tee: optee: Add SMC for loading OP-TEE image
Adds an SMC call that will pass an OP-TEE binary image to EL3 and instruct it to load it as the BL32 payload. This works in conjunction with a feature added to Trusted Firmware for ARMv8 and above architectures that supports this. The main purpose of this change is to facilitate updating the OP-TEE component on devices via a rootfs change rather than having to do a firmware update. Further details are linked to in the Kconfig file.

tee: Pass a pointer to virt_to_page()
Like the other calls in this function virt_to_page() expects a pointer, not an integer. However since many architectures implement virt_to_pfn() as a macro, this function becomes polymorphic and accepts both a (unsigned long) and a (void *). Fix this up with an explicit cast.

optee: add per cpu asynchronous notification
Implements use of per-cpu irq for optee asynchronous notification. Existing optee async notif implementation allows OP-TEE world to raise an interrupt on which Linux optee driver will query some pending events. This change allows the signaling interrupt to be a per-cpu interrupt as with Arm GIC PPIs. Using a PPI instead of an SPI is useful when no GIC lines are provisioned in the chip design and there are spare PPI lines.

tee: amdtee: fix race condition in amdtee_open_session
There is a potential race condition in amdtee_open_session that may
lead to use-after-free. For instance, in amdtee_open_session() after
sess->sess_mask is set, and before setting:
sess->session_info[i] = session_info;
if amdtee_close_session() closes this same session, then 'sess' data
structure will be released, causing kernel panic when 'sess' is
accessed within amdtee_open_session().
The solution is to set the bit sess->sess_mask as the last step in
amdtee_open_session().

Driver core changes for 6.3-rc1
Here is the large set of driver core changes for 6.3-rc1.
There's a lot of changes this development cycle, most of the work falls
into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be moved
into read-only memory (i.e. const) The recent work with Rust has
pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only making
things safer overall. This is the contuation of that work (started
last release with kobject changes) in moving struct bus_type to be
constant. We didn't quite make it for this release, but the
remaining patches will be finished up for the release after this
one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems.

The kernel pages used by shm_get_kernel_pages() are allocated using GFP_KERNEL through the following call stack: trusted_instantiate() trusted_payload_alloc() -> GFP_KERNEL <trusted key op> tee_shm_register_kernel_buf() register_shm_helper() shm_get_kernel_pages() Where <trusted key op> is one of: trusted_key_unseal() trusted_key_get_random() trusted_key_seal() Because the pages can't be from highmem get_kernel_pages() boils down to a get_page() call. Remove the get_kernel_pages() call and open code the get_page(). In case a highmem page does slip through warn on once for a kmap'ed address.

SoC driver updates for 6.2
There are few major updates in the SoC specific drivers, mainly the usual
reworks and support for variants of the existing SoC. While this remains
Arm centric for the most part, the branch now also contains updates to
risc-v and loongarch specific code in drivers/soc/.
Notable changes include:
- Support for the newly added Qualcomm Snapdragon variants
(MSM8956, MSM8976, SM6115, SM4250, SM8150, SA8155 and SM8550) in the
soc ID, rpmh, rpm, spm and powerdomain drivers.
- Documentation for the somewhat controversial qcom,board-id
properties that are required for booting a number of machines
- A new SoC identification driver for the loongson-2 (loongarch)
platform
- memory controller updates for stm32, tegra, and renesas.
- a new DT binding to better describe LPDDR2/3/4/5 chips in
the memory controller subsystem
- Updates for Tegra specific drivers across multiple subsystems,
improving support for newer SoCs and better identification
- Minor fixes for Broadcom, Freescale, Apple, Renesas, Sifive,
TI, Mediatek and Marvell SoC drivers

tee: optee: fix possible memory leak in optee_register_device()
If device_register() returns error in optee_register_device(),
the name allocated by dev_set_name() need be freed. As comment
of device_register() says, it should use put_device() to give
up the reference in the error path. So fix this by calling
put_device(), then the name can be freed in kobject_cleanup(),
and optee_device is freed in optee_release_device().
Fixes:

ARM: driver updates for 6.1
The drivers branch for 6.1 is a bit larger than for most releases. Most
of the changes come from SoC maintainers for the drivers/soc subsystem:
- A new driver for error handling on the NVIDIA Tegra
'control backbone' bus.
- A new driver for Qualcomm LLCC/DDR bandwidth measurement
- New Rockchip rv1126 and rk3588 power domain drivers
- DT binding updates for memory controllers, older Rockchip
SoCs, various Mediatek devices, Qualcomm SCM firmware
- Minor updates to Hisilicon LPC bus, the Allwinner SRAM
driver, the Apple rtkit firmware driver, Tegra firmware
- Minor updates for SoC drivers (Samsung, Mediatek, Renesas,
Tegra, Qualcomm, Broadcom, NXP, ...)
There are also some separate subsystem with downstream maintainers that
merge updates this way:
- Various updates and new drivers in the memory controller
subsystem for Mediatek and Broadcom SoCs
- Small set of changes in preparation to add support for FF-A
v1.1 specification later, in the Arm FF-A firmware subsystem
- debugfs support in the PSCI firmware subsystem

Arm FF-A firmware driver updates for v6.1
Small set of changes in preparation to add support for FF-A v1.1
specification later. It mainly contains:
1. Splitting up ffa_ops into different categories namely information,
message and memory. It helps to make info and memory operations
independent from ffa_device so thata generic memory management
module can use it without specific ffa_dev.
2. Adds support for querying FF-A features and use the same to detect
the support for 64-bit operations.
3. Adds v1.1 get_partition_info support and use the same to set up

Merge tag 'ffa-updates-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/drivers
Arm FF-A firmware driver updates for v6.1
Small set of changes in preparation to add support for FF-A v1.1
specification later. It mainly contains:
1. Splitting up ffa_ops into different categories namely information,
message and memory. It helps to make info and memory operations
independent from ffa_device so thata generic memory management
module can use it without specific ffa_dev.
2. Adds support for querying FF-A features and use the same to detect
the support for 64-bit operations.
3. Adds v1.1 get_partition_info support and use the same to set up
32-bit execution mode flag automatically.
4. Adds pointer to the ffa_dev_ops in struct ffa_dev and drop
ffa_dev_ops_get() which enables to drop ffa_ops in optee_ffa
structure using ffa_dev->ops directly. Additionally ffa_dev_ops is
renamed as ffa_ops.

firmware: arm_ffa: Split up ffa_ops into info, message and memory operations
In preparation to make memory operations accessible for a non ffa_driver/device, it is better to split the ffa_ops into different categories of operations: info, message and memory. The info and memory are ffa_device independent and can be used without any associated ffa_device from a non ffa_driver. However, we don't export these info and memory APIs yet without the user. The first users of these APIs can export them.

firmware: arm_ffa: Rename ffa_dev_ops as ffa_ops
Except the message APIs, all other APIs are ffa_device independent and can be used without any associated ffa_device from a non ffa_driver. In order to reflect the same, just rename ffa_dev_ops as ffa_ops to avoid any confusion or to keep it simple.

firmware: arm_ffa: Make memory apis ffa_device independent
There is a requirement to make memory APIs independent of the ffa_device. One of the use-case is to have a common memory driver that manages the memory for all the ffa_devices. That common memory driver won't be a ffa_driver or won't have any ffa_device associated with it. So having these memory APIs accessible without a ffa_device is needed and should be possible as most of these are handled by the partition manager(SPM or hypervisor). Drop the ffa_device argument to the memory APIs and make them ffa_device independent.

tee: optee: Drop ffa_ops in optee_ffa structure using ffa_dev->ops directly
Now that the ffa_device structure holds the pointer to ffa_dev_ops, there is no need to obtain the same through ffa_dev_ops_get(). Just use the ffa_dev->ops directly. Since the ffa_device itself carries ffa_dev_ops now, there is no need to keep a copy in optee_ffa structure. Drop ffa_ops in the optee_ffa structure as it is not needed anymore.

tee: add overflow check in register_shm_helper()
With special lengths supplied by user space, register_shm_helper() has
an integer overflow when calculating the number of pages covered by a

This causes internal_get_user_pages_fast() a helper function of

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.

Couple of fixes to handle fragmented memory descriptors and incorrect UUID parameter passed to ffa_partition_probe.

tee: optee: Use ffa_dev_get_drvdata to fetch driver_data
Due to lack of an helper like ffa_dev_get_drvdata, this driver was fetching driver_data directly accessing the structure member. Now that we have added an helper, just use the same instead.

tee: remove flags TEE_IOCTL_SHM_MAPPED and TEE_IOCTL_SHM_DMA_BUF
These look to be leftover from an early edition of this driver. Userspace
does not need this information. Checking all users of this that I have
access to I have verified no one is using them.
They leak internal use flags out to userspace. Even more they are not
correct anymore after
