Merge tag 'soc-drivers-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull SoC driver updates from Arnd Bergmann:
"Lots of platform specific updates for Qualcomm SoCs, including a new
TEE subsystem driver for the Qualcomm QTEE firmware interface.

Added support for the Apple A11 SoC in drivers that are shared with
the M1/M2 series, among more updates for those.

Smaller platform specific driver updates for Renesas, ASpeed,
Broadcom, Nvidia, Mediatek, Amlogic, TI, Allwinner, and Freescale
SoCs.

Driver updates in the cache controller, memory controller and reset
controller subsystems.

SCMI firmware updates to add more features and improve robustness.
This includes support for having multiple SCMI providers in a single
system.

TEE subsystem support for protected DMA-bufs, allowing hardware to
access memory areas that managed by the kernel but remain inaccessible
from the CPU in EL1/EL0"

Add Qualcomm TEE driver (QTEE)

This introduces a Trusted Execution Environment (TEE) driver for
Qualcomm TEE (QTEE).

QTEE enables Trusted Applications (TAs) and services to run securely. It
uses an object-based interface, where each service is an object with
sets of operations.

Kernel and userspace services are also available to QTEE through a
similar approach. QTEE makes callback requests that are converted into
object invocations. These objects can represent services within the
kernel or userspace process.

We extend the TEE subsystem to understand object parameters and an ioctl
call so client can invoke objects in QTEE:
- TEE_IOCTL_PARAM_ATTR_TYPE_OBJREF_*
- TEE_IOC_OBJECT_INVOKE

The existing ioctl calls TEE_IOC_SUPPL_RECV and TEE_IOC_SUPPL_SEND are
used for invoking services in the userspace process by QTEE.

The TEE backend driver uses the QTEE Transport Message to communicate
with QTEE. Interactions through the object INVOKE interface are
translated into QTEE messages. Likewise, object invocations from QTEE
for userspace objects are converted into SEND/RECV ioctl calls to
supplicants.

tee: qcom: enable TEE_IOC_SHM_ALLOC ioctl

Enable userspace to allocate shared memory with QTEE. Since

tee: qcom: enable TEE_IOC_SHM_ALLOC ioctl

Enable userspace to allocate shared memory with QTEE. Since
QTEE handles shared memory as object, a wrapper is implemented
to represent tee_shm as an object. The shared memory identifier,
obtained through TEE_IOC_SHM_ALLOC, is transferred to the driver using
TEE_IOCTL_PARAM_ATTR_TYPE_OBJREF_INPUT/OUTPUT.
