Pull ARM driver updates from Arnd Bergmann:
"These are the usual updates for SoC specific device drivers and
related subsystems that don't have their own top-level maintainers:
- ARM SCMI/SCPI updates to allow pluggable transport layers
- TEE subsystem cleanups
- A new driver for the Amlogic secure power domain controller
- Various driver updates for the NXP Layerscape DPAA2, NXP i.MX SCU
and TI OMAP2+ sysc drivers.
- Qualcomm SoC driver updates, including a new library module for
"protection domain" notifications
- Lots of smaller bugfixes and cleanups in other drivers"

Cleanup shared memory handing in TEE subsystem
The highlights are:
- Removing redundant or unused fields in struct tee_shm
- Only assign userspace shm IDs for shared memory objects originating from
user space
* tag 'tee-cleanup-for-5.7' of https://git.linaro.org/people/jens.wiklander/linux-tee:
tee: tee_shm_op_mmap(): use TEE_SHM_USER_MAPPED
tee: remove redundant teedev in struct tee_shm

tee: remove unused tee_shm_priv_alloc()
tee: remove linked list of struct tee_shm

tee_shm_op_mmap() uses the TEE_SHM_USER_MAPPED flag instead of the
TEE_SHM_REGISTER flag to tell if a shared memory object is originating
from registered user space memory.

The ctx element in struct tee_shm is always valid. So remove the now
redundant teedev element.

Private shared memory object must not be referenced from user space. To
guarantee that, don't assign an id to shared memory objects which are
driver private.

The "index" is a user provided value from 0-USHRT_MAX. If it's over
TEE_NUM_SESSIONS (31) then it results in an out of bounds read when we
call test_bit(index, sess->sess_mask).

On these error paths the "sess" variable isn't freed. It's a refcounted
pointer so we need to call kref_put(). I re-arranged the code a bit so
the error case is always handled before the success case and the error
paths are indented two tabs.

To simplify adding ACPI support to the OP-TEE driver, model it as
a platform driver. This will permit us to use the generic device
property layer for parsing additional properties, regardless of
whether DT or ACPI is being used.
Note that this change will result in the OP-TEE driver to be loaded
automatically on systems that advertise the presence of OP-TEE via
the device tree.

The AMD-TEE driver should check if TEE is available before
registering itself with TEE subsystem. This ensures that
there is a TEE which the driver can talk to before proceeding
with tee device node allocation.

* defines tee_driver_ops function callbacks
* kernel allocated memory is used as shared memory between normal

The optee driver uses specific page table types to verify if a memory
region is normal. These types are not defined in nommu systems. Trying
to compile the driver in these systems results in a build error:

The .ioctl and .compat_ioctl file operations have the same prototype so
they can both point to the same function, which works great almost all
the time when all the commands are compatible.
One exception is the s390 architecture, where a compat pointer is only
31 bit wide, and converting it into a 64-bit pointer requires calling
compat_ptr(). Most drivers here will never run in s390, but since we now
have a generic helper for it, it's easy enough to use it consistently.
I double-checked all these drivers to ensure that all ioctl arguments
are used as pointers or are ignored, but are not interpreted as integer
values.

Prior to this patch in optee_probe() when optee_enumerate_devices() was
called the struct optee was fully initialized. If
optee_enumerate_devices() returns an error optee_probe() is supposed to
clean up and free the struct optee completely, but will at this late
stage need to call optee_remove() instead. This isn't done and thus
freeing the struct optee prematurely.
With this patch the call to optee_enumerate_devices() is done after
optee_probe() has returned successfully and in case
optee_enumerate_devices() fails everything is cleaned up with a call to
optee_remove().

In case of dynamic shared memory pool, kernel memory allocated using
dmabuf_mgr pool needs to be registered with OP-TEE prior to its usage
during optee_open_session() or optee_invoke_func().
So fix dmabuf_mgr pool allocations via an additional call to
optee_shm_register().
Also, allow kernel pages to be registered as shared memory with OP-TEE.

This patch is a part of a series that extends kernel ABI to allow to pass
tagged user pointers (with the top byte set to something else other than
0x00) as syscall arguments.
tee_shm_register()->optee_shm_unregister()->check_mem_type() uses provided
user pointers for vma lookups (via __check_mem_type()), which can only by
done with untagged pointers.
Untag user pointers in this function.

If the kernel is compiled with CONFIG_PREEMPT_VOLUNTARY and OP-TEE is
executing a long running workload, the following errors are raised:

While OP-TEE is returning regularly to the kernel due to timer
interrupts, the OPTEE_SMC_FUNC_FOREIGN_INTR case does not contain an
explicit rescheduling point. Add a might_sleep() to the RPC request case
to ensure that the kernel can reschedule another task if OP-TEE requests
RPC handling.

On virtualized systems it is possible that OP-TEE will provide
only dynamic shared memory support. So it is fine to boot
without static SHM enabled if dymanic one is supported.

To facilitate additional options to get_user_pages_fast() change the
singular write parameter to be gup_flags.
This patch does not change any functionality. New functionality will
follow in subsequent patches.
Some of the get_user_pages_fast() call sites were unchanged because they
already passed FOLL_WRITE or 0 for the write parameter.
NOTE: It was suggested to change the ordering of the get_user_pages_fast()
arguments to ensure that callers were converted. This breaks the current
GUP call site convention of having the returned pages be the final
parameter. So the suggestion was rejected.

Pull ARM SoC driver updates from Arnd Bergmann:
"As usual, the drivers/tee and drivers/reset subsystems get merged
here, with the expected set of smaller updates and some new hardware
support. The tee subsystem now supports device drivers to be attached
to a tee, the first example here is a random number driver with its
implementation in the secure world.
Three new power domain drivers get added for specific chip families:
- Broadcom BCM283x chips (used in Raspberry Pi)
- Qualcomm Snapdragon phone chips
- Xilinx ZynqMP FPGA SoCs
One new driver is added to talk to the BPMP firmware on NVIDIA
Tegra210
Existing drivers are extended for new SoC variants from NXP, NVIDIA,
Amlogic and Qualcomm"

Add support of cancellation request to the TEE kernel internal
client interface. Can be used by software TPM drivers, that leverage
TEE under the hood (for instance TPM2.0 mobile profile), for requesting

The return from the call to tee_client_invoke_func can be a
negative error code however this is being assigned to an
unsigned variable 'ret' hence the check is always false.
Fix this by making 'ret' an int.
