Pull ARM SoC fixes from Arnd Bergmann: "Another set of patches for devicetree files and Arm SoC specific drivers: - A fix for OP-TEE shared memory on non-SMP systems - multiple code fixes for the OMAP platform, including one regression for the CPSW network driver and a few runtime warning fixes - Some DT patches for the Rockchip RK3399 platform, in particular fixing the MMC device ordering that recently became nondeterministic with async probe. - Multiple DT fixes for the Tegra platform, including a regression fix for suspend/resume on TX2 - A regression fix for a user-triggered fault in the NXP dpio driver - A regression fix for a bug caused by an earlier bug fix in the xilinx firmware driver - Two more DTC warning fixes - Sylvain Lemieux steps down as maintainer for the NXP LPC32xx platform" * tag 'arm-soc-fixes-v5.10-3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (24 commits) arm64: tegra: Fix Tegra234 VDK node names arm64: tegra: Wrong AON HSP reg property size arm64: tegra: Fix USB_VBUS_EN0 regulator on Jetson TX1 arm64: tegra: Correct the UART for Jetson Xavier NX arm64: tegra: Disable the ACONNECT for Jetson TX2 optee: add writeback to valid memory type firmware: xilinx: Use hash-table for api feature check firmware: xilinx: Fix SD DLL node reset issue soc: fsl: dpio: Get the cpumask through cpumask_of(cpu) ARM: dts: dra76x: m_can: fix order of clocks bus: ti-sysc: suppress err msg for timers used as clockevent/source MAINTAINERS: Remove myself as LPC32xx maintainers arm64: dts: qcom: clear the warnings caused by empty dma-ranges arm64: dts: broadcom: clear the warnings caused by empty dma-ranges ARM: dts: am437x-l4: fix compatible for cpsw switch dt node arm64: dts: rockchip: Reorder LED triggers from mmc devices on rk3399-roc-pc. arm64: dts: rockchip: Assign a fixed index to mmc devices on rk3399 boards. arm64: dts: rockchip: Remove system-power-controller from pmic on Odroid Go Advance arm64: dts: rockchip: fix NanoPi R2S GMAC clock name ARM: OMAP2+: Manage MPU state properly for omap_enter_idle_coupled() ...

optee: add writeback to valid memory type

2020-11-25T11:51:52Z

Only in smp systems the cache policy is setup as write alloc, in single cpu systems the cache policy is set as writeback and it is normal memory, so, it should pass the is_normal_memory check in the share memory registration. Add the right condition to make it work in no smp systems. Fixes: cdbcf83d29c1 ("tee: optee: check type of registered shared memory") Signed-off-by: Rui Miguel Silva Signed-off-by: Jens Wiklander

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. * tag 'amdtee-fixes-for-5.10' of git://git.linaro.org:/people/jens.wiklander/linux-tee: tee: amdtee: synchronize access to shm list tee: amdtee: fix memory leak due to reset of global shm list Link: https://lore.kernel.org/r/20201109080809.GA3862873@jade Signed-off-by: Arnd Bergmann

tee: amdtee: synchronize access to shm list

Synchronize access to shm or shared memory buffer list to prevent race conditions due to concurrent updates to shared shm list by multiple threads. Fixes: 757cc3e9ff1d ("tee: add AMD-TEE driver") Reviewed-by: Devaraj Rangasamy Signed-off-by: Rijo Thomas Signed-off-by: Jens Wiklander

tee: amdtee: fix memory leak due to reset of global shm list

2020-11-09T07:58:54Z

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.

tee: client UUID: Skip REE kernel login method as well

2020-10-13T06:42:11Z

Since the addition of session's client UUID generation via commit [1], login via REE kernel method was disallowed. So fix that via passing nill UUID in case of TEE_IOCTL_LOGIN_REE_KERNEL method as well.

tee: avoid explicit sysfs_create/delete_group by initialising dev->groups

2020-09-18T08:44:45Z

If the dev->groups is initialised, the sysfs group is created as part of device_add call. There is no need to call sysfs_create/delete_group explicitly. Signed-off-by: Sudeep Holla Signed-off-by: Jens Wiklander

tee: replace cdev_add + device_add with cdev_device_add

2020-09-18T08:44:40Z

Commit 233ed09d7fda ("chardev: add helper function to register char devs with a struct device") added a helper function 'cdev_device_add'. Make use of cdev_device_add in tee_device_register to replace cdev_add and device_add. Since cdev_device_add takes care of setting the kobj->parent, drop explicit initialisation in tee_device_alloc.
