Here is the big set of char and misc and other tiny driver subsystem
updates for 5.16-rc1.
Loads of things in here, all of which have been in linux-next for a
while with no reported problems (except for one called out below.)
Included are:
- habanana labs driver updates, including dma_buf usage,
reviewed and acked by the dma_buf maintainers
- iio driver update (going through this tree not staging as they
really do not belong going through that tree anymore)
- counter driver updates
- hwmon driver updates that the counter drivers needed, acked by
the hwmon maintainer
- xillybus driver updates
- binder driver updates
- extcon driver updates
- dma_buf module namespaces added (will cause a build error in
arm64 for allmodconfig, but that change is on its way through
the drm tree)
- lkdtm driver updates
- pvpanic driver updates
- phy driver updates
- virt acrn and nitr_enclaves driver updates

In order to better track where in the kernel the dma-buf code is used,
put the symbols in the namespace DMA_BUF and modify all users of the
symbols to properly import the namespace to not break the build at the
same time.
Now the output of modinfo shows the use of these symbols, making it
easier to watch for users over time:

Adds support for using FF-A [1] as transport to the OP-TEE driver.
Introduces struct optee_msg_param_fmem which carries all information
needed when OP-TEE is calling FFA_MEM_RETRIEVE_REQ to get the shared
memory reference mapped by the hypervisor in S-EL2. Register usage is
also updated to include the information needed.
The FF-A part of this driver is enabled if CONFIG_ARM_FFA_TRANSPORT is
enabled.

Isolate the ABI based on raw SMCs. Code specific to the raw SMC ABI is
moved into smc_abi.c. This makes room for other ABIs with a clear
separation.
The driver changes to use module_init()/module_exit() instead of
module_platform_driver(). The platform_driver_register() and
platform_driver_unregister() functions called directly to keep the same
behavior. This is needed because module_platform_driver() is based on
module_driver() which can only be used once in a module.
A function optee_rpc_cmd() is factored out from the function
handle_rpc_func_cmd() to handle the ABI independent part of RPC
processing.
This patch is not supposed to change the driver behavior, it's only a
matter of reorganizing the code.

The OP-TEE driver is refactored with three internal callbacks replacing
direct calls to optee_from_msg_param(), optee_to_msg_param() and
optee_do_call_with_arg().
These functions a central to communicating with OP-TEE in secure world
by using the SMC Calling Convention directly.
This refactoring makes room for using other primitives to communicate
with OP-TEE in secure world while being able to reuse as much as
possible from the present driver.

Currently TEE_SHM_DMA_BUF flag has been inappropriately used to not
register shared memory allocated for private usage by underlying TEE
driver: OP-TEE in this case. So rather add a new flag as TEE_SHM_PRIV
that can be utilized by underlying TEE drivers for private allocation
and usage of shared memory.
With this corrected, allow tee_shm_alloc_kernel_buf() to allocate a
shared memory region without the backing of dma-buf.

The shm cache could contain invalid addresses if
optee_disable_shm_cache() was not called from the .shutdown hook of the
previous kernel before a kexec. These addresses could be unmapped or
they could point to mapped but unintended locations in memory.
Clear the shared memory cache, while being careful to not translate the
addresses returned from OPTEE_SMC_DISABLE_SHM_CACHE, during driver
initialization. Once all pre-cache shm objects are removed, proceed with
enabling the cache so that we know that we can handle cached shm objects
with confidence later in the .shutdown hook.

OP-TEE skip check of returned memref size
* tag 'optee-memref-size-for-v5.13' of git://git.linaro.org/people/jens.wiklander/linux-tee:
tee: optee: do not check memref size on return from Secure World

When Secure World returns, it may have changed the size attribute of the
memory references passed as [in/out] parameters. The GlobalPlatform TEE
Internal Core API specification does not restrict the values that this
size can take. In particular, Secure World may increase the value to be
larger than the size of the input buffer to indicate that it needs more.
Therefore, the size check in optee_from_msg_param() is incorrect and
needs to be removed. This fixes a number of failed test cases in the
GlobalPlatform TEE Initial Configuratiom Test Suite v2_0_0_0-2017_06_09
when OP-TEE is compiled without dynamic shared memory support
(CFG_CORE_DYN_SHM=n).

There are a couple of subsystems maintained by other people that
merge their drivers through the SoC tree, those changes include:
- The SCMI firmware framework gains support for sensor notifications
and for controlling voltage domains.
- A large update for the Tegra memory controller driver, integrating
it better with the interconnect framework
- The memory controller subsystem gains support for Mediatek MT8192
- The reset controller framework gains support for sharing pulsed
resets
For Soc specific drivers in drivers/soc, the main changes are
- The Allwinner/sunxi MBUS gets a rework for the way it handles
dma_map_ops and offsets between physical and dma address spaces.
- An errata fix plus some cleanups for Freescale Layerscape SoCs
- A cleanup for renesas drivers regarding MMIO accesses.
- New SoC specific drivers for Mediatek MT8192 and MT8183 power domains
- New SoC specific drivers for Aspeed AST2600 LPC bus control
and SoC identification.
- Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660
and SDX55.
- A rework of the TI AM33xx 'genpd' power domain support to use
information from DT instead of platform data
- Support for TI AM64x SoCs
- Allow building some Amlogic drivers as modules instead of built-in
Finally, there are numerous cleanups and smaller bug fixes for
Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
Renesas, and Xilinx SoCs.

Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2,
and <crypto/sha3.h> contains declarations for SHA-3.
This organization is inconsistent, but more importantly SHA-1 is no
longer considered to be cryptographically secure. So to the extent
possible, SHA-1 shouldn't be grouped together with any of the other SHA
versions, and usage of it should be phased out.
Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and
<crypto/sha2.h>, and make everyone explicitly specify whether they want
the declarations for SHA-1, SHA-2, or both.
This avoids making the SHA-1 declarations visible to files that don't
want anything to do with SHA-1. It also prepares for potentially moving
sha1.h into a new insecure/ or dangerous/ directory.

Synchronize access to shm or shared memory buffer list to prevent
race conditions due to concurrent updates to shared shm list by
multiple threads.

The driver maintains a list of shared memory buffers along with their
mapped buffer id's in a global linked list. These buffers need to be
unmapped after use by the user-space client.
The global shared memory list is initialized to zero entries in the
function amdtee_open(). This clearing of list entries can be a source
for memory leak on secure side if the global linked list previously
held some mapped buffer entries allocated from another TEE context.
Fix potential memory leak issue by moving global shared memory list
to AMD-TEE driver context data structure.

There is export_uuid() function which exports uuid_t to the u8 array.
Use it instead of open coding variant.
This allows to hide the uuid_t internals.
