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" * tag 'arm-drivers-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (70 commits) soc: fsl: qe: fix sparse warnings for ucc_slow.c soc: fsl: qe: ucc_slow: remove 0 assignment for kzalloc'ed structure soc: fsl: qe: fix sparse warnings for ucc_fast.c soc: fsl: qe: fix sparse warnings for qe_ic.c soc: fsl: qe: fix sparse warnings for ucc.c soc: fsl: qe: fix sparse warning for qe_common.c soc: fsl: qe: fix sparse warnings for qe.c soc: qcom: Fix QCOM_APR dependencies soc: qcom: pdr: Avoid uninitialized use of found in pdr_indication_cb soc: imx: drop COMPILE_TEST for IMX_SCU_SOC firmware: imx: add COMPILE_TEST for IMX_SCU driver soc: imx: gpc: fix power up sequencing soc: imx: increase build coverage for imx8m soc driver soc: qcom: apr: Add avs/audio tracking functionality dt-bindings: soc: qcom: apr: Add protection domain bindings soc: qcom: Introduce Protection Domain Restart helpers devicetree: bindings: firmware: add ipq806x to qcom_scm memory: tegra: Correct debugfs clk rate-range on Tegra124 memory: tegra: Correct debugfs clk rate-range on Tegra30 memory: tegra: Correct debugfs clk rate-range on Tegra20 ...

tee: amdtee: out of bounds read in find_session()

2020-03-10T07:12:04Z

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).

tee: tee_shm_op_mmap(): use TEE_SHM_USER_MAPPED

2020-02-28T12:37:42Z

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. Signed-off-by: Jens Wiklander

tee: remove redundant teedev in struct tee_shm

2020-02-28T12:37:42Z

The ctx element in struct tee_shm is always valid. So remove the now redundant teedev element. Signed-off-by: Jens Wiklander

tee: don't assign shm id for private shms

2020-02-28T12:37:42Z

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. Signed-off-by: Jens Wiklander

tee: remove unused tee_shm_priv_alloc()

2020-02-28T12:37:42Z

tee_shm_priv_alloc() isn't useful in the current state and it's also not not used so remove it. Signed-off-by: Jens Wiklander

tee: remove linked list of struct tee_shm

2020-02-28T12:37:42Z

Removes list_shm from struct tee_context since the linked list isn't used any longer. Signed-off-by: Jens Wiklander
