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.

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.

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 a45ea4efa3. Lets drop these flags before
someone does try to use them for something and they become ABI.

Adds OPTEE_SMC_CALL_WITH_RPC_ARG and OPTEE_SMC_CALL_WITH_REGD_ARG where
the struct optee_msg_arg to be used for RPC is appended in the memory
following the normal argument struct optee_msg_arg. This is an
optimization to avoid caching the RPC argument struct while still
maintaining similar performance as if it was cached.
OPTEE_SMC_CALL_WITH_REGD_ARG optimized one step further by using a
registered shared memory object instead. It's in other aspects identical
to OPTEE_SMC_CALL_WITH_RPC_ARG.
The presence of OPTEE_SMC_CALL_WITH_RPC_ARG and
OPTEE_SMC_CALL_WITH_REGD_ARG is indicated by the new
OPTEE_SMC_SEC_CAP_RPC_ARG bit returned by
OPTEE_SMC_EXCHANGE_CAPABILITIES. OPTEE_SMC_EXCHANGE_CAPABILITIES also
reports the number of arguments that the RPC argument struct must have
room for.
OPTEE_SMC_CALL_WITH_RPC_ARG and OPTEE_SMC_CALL_WITH_ARG can be used
interleaved with difference that when OPTEE_SMC_CALL_WITH_RPC_ARG is
used the RPC argument struct to be used is the one appended to the
normal argument struct. The same is true for
OPTEE_SMC_CALL_WITH_REGD_ARG.

tee_shm_alloc() is replaced by three new functions,
tee_shm_alloc_user_buf() - for user mode allocations, replacing passing
the flags TEE_SHM_MAPPED | TEE_SHM_DMA_BUF
tee_shm_alloc_kernel_buf() - for kernel mode allocations, slightly
optimized compared to using the flags TEE_SHM_MAPPED | TEE_SHM_DMA_BUF.
tee_shm_alloc_priv_buf() - primarily for TEE driver internal use.
This also makes the interface easier to use as we can get rid of the
somewhat hard to use flags parameter.

Replaces the shared memory pool based on two pools with a single pool.
The alloc() function pointer in struct tee_shm_pool_ops gets another
parameter, align. This makes it possible to make less than page aligned
allocations from the optional reserved shared memory pool while still
making user space allocations page aligned. With in practice unchanged
behaviour using only a single pool for bookkeeping.
The allocation algorithm in the static OP-TEE shared memory pool is
changed from best-fit to first-fit since only the latter supports an
alignment parameter. The best-fit algorithm was previously the default
choice and not a conscious one.
The optee and amdtee drivers are updated as needed to work with this
changed pool handling.
This also removes OPTEE_SHM_NUM_PRIV_PAGES which becomes obsolete with
this change as the private pages can be mixed with the payload pages.
The OP-TEE driver changes minimum alignment for argument struct from 8
bytes to 512 bytes. A typical OP-TEE private shm allocation is 224 bytes
(argument struct with 6 parameters, needed for open session). So with an
alignment of 512 well waste a bit more than 50%. Before this we had a
single page reserved for this so worst case usage compared to that would
be 3 pages instead of 1 page. However, this worst case only occurs if
there is a high pressure from multiple threads on secure world. All in
all this should scale up and down better than fixed boundaries.

Adds a driver private tee_context by moving the tee_context in struct
optee_notif to struct optee. This tee_context was previously used when
doing internal calls to secure world to deliver notification.
The new driver internal tee_context is now also when allocating driver
private shared memory. This decouples the shared memory object from its
original tee_context. This is needed when the life time of such a memory
allocation outlives the client tee_context.
This patch fixes the problem described below:
The addition of a shutdown hook by commit f25889f931 ("optee: fix tee out
of memory failure seen during kexec reboot") introduced a kernel shutdown
regression that can be triggered after running the OP-TEE xtest suites.
Once the shutdown hook is called it is not possible to communicate any more
with the supplicant process because the system is not scheduling task any
longer. Thus if the optee driver shutdown path receives a supplicant RPC
request from the OP-TEE we will deadlock the kernel's shutdown.

Since the tee subsystem does not keep a strong reference to its idle
shared memory buffers, it races with other threads that try to destroy a
shared memory through a close of its dma-buf fd or by unmapping the
memory.
In tee_shm_get_from_id() when a lookup in teedev->idr has been
successful, it is possible that the tee_shm is in the dma-buf teardown
path, but that path is blocked by the teedev mutex. Since we don't have
an API to tell if the tee_shm is in the dma-buf teardown path or not we
must find another way of detecting this condition.
Fix this by doing the reference counting directly on the tee_shm using a
new refcount_t refcount field. dma-buf is replaced by using
anon_inode_getfd() instead, this separates the life-cycle of the
underlying file from the tee_shm. tee_shm_put() is updated to hold the
mutex when decreasing the refcount to 0 and then remove the tee_shm from
teedev->idr before releasing the mutex. This means that the tee_shm can
never be found unless it has a refcount larger than 0.

Adds support for asynchronous notifications from secure world to normal
world. This allows a design with a top half and bottom half type of
driver where the top half runs in secure interrupt context and a
notifications tells normal world to schedule a yielding call to do the
bottom half processing.
The protocol is defined in optee_msg.h optee_rpc_cmd.h and optee_smc.h.
A notification consists of a 32-bit value which normal world can
retrieve using a fastcall into secure world. The value
OPTEE_SMC_ASYNC_NOTIF_VALUE_DO_BOTTOM_HALF (0) has a special meaning.
When this value is sent it means that normal world is supposed to make a
yielding call OPTEE_MSG_CMD_DO_BOTTOM_HALF.
Notification capability is negotiated while the driver is initialized.
If both sides supports these notifications then they are enabled.
An interrupt is used to notify the driver that there are asynchronous
notifications pending. The maximum needed notification value is
communicated at this stage. This allows scaling up when needed.

Renames struct optee_wait_queue to struct optee_notif and all related
functions to optee_notif_*().
The implementation is changed to allow sending a notification from an
atomic state, that is from the top half of an interrupt handler.
Waiting for keys is currently only used when secure world is waiting for
a mutex or condition variable. The old implementation could handle any
32-bit key while this new implementation is restricted to only 8 bits or
the maximum value 255. A upper value is needed since a bitmap is
allocated to allow an interrupt handler to only set a bit in case the
waiter hasn't had the time yet to allocate and register a completion.
The keys are currently only representing secure world threads which
number usually are never even close to 255 so it should be safe for now.

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

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.

These functions a central to communicating with OP-TEE in secure world
by using the SMC Calling Convention directly.

Currently TEE_SHM_DMA_BUF flag has been inappropriately used to not

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

Clear the shared memory cache, while being careful to not translate the

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.

AMD-TEE driver bug fixes
AMD-TEE driver keeps track of shared memory buffers and their
corresponding buffer id's in a global linked list. These buffers are
used to share data between x86 and AMD Secure Processor. This pull
request fixes issues related to maintaining mapped buffers in a shared
linked list.

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.

Make use of cdev_device_add in tee_device_register to replace cdev_add

When the optee driver is compiled into the kernel while the i2c core
is configured as a module, the i2c symbols are not available.
This commit addresses the situation by disabling the i2c support for
this use case while allowing it in all other scenarios:
i2c=y, optee=y
i2c=m, optee=m
i2c=y, optee=m
i2c=m, optee=y (not supported)
