2021-10-22soc: aspeed: Add UART routing supportChia-Wei Wang4-4/+645
Add driver support for the UART routing control. Users can perform runtime configuration of the RX muxes among the UART controllers and the UART IO pins. The sysfs interface is also exported for the convenience of routing paths check and update.

2021-10-18optee: isolate smc abiJens Wiklander8-1388/+1506
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.

Support for releasing secondary CPUs on MSM8226 is introduced. The Asynchronous Packet Router (APR) driver is extended to support the new Generic Packet Router (GPR) variant, which is used to communicate with the firmware in the new AudioReach audio driver. Lastly it transitions a number of drivers to safer string functions, as well as switching things to use devm_platform_ioremap_resource(). * tag 'qcom-drivers-for-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (40 commits) soc: qcom: apr: Add GPR support soc: dt-bindings: qcom: add gpr bindings soc: qcom: apr: make code more reuseable soc: dt-bindings: qcom: apr: deprecate qcom,apr-domain property soc: dt-bindings: qcom: apr: convert to yaml dt-bindings: soc: qcom: aoss: Delete unused power-domain definitions dt-bindings: msm/dp: Remove aoss-qmp header soc: qcom: aoss: Drop power domain support dt-bindings: soc: qcom: aoss: Drop the load state power-domain soc: qcom: smp2p: Add wakeup capability to SMP2P IRQ dt-bindings: power: rpmpd: Add SM6350 to rpmpd binding dt-bindings: soc: qcom: aoss: Add SM6350 compatible soc: qcom: llcc: Disable MMUHWT retention soc: qcom: smd-rpm: Add QCM2290 compatible dt-bindings: soc: qcom: smd-rpm: Add QCM2290 compatible firmware: qcom_scm: Add compatible for MSM8953 SoC dt-bindings: firmware: qcom-scm: Document msm8953 bindings soc: qcom: pdr: Prefer strscpy over strcpy soc: qcom: rpmh-rsc: Make use of the helper function devm_platform_ioremap_resource_byname() soc: qcom: gsbi: Make use of the helper function devm_platform_ioremap_resource() ...

2021-10-13bus: sun50i-de2: Adjust printing error messageJernej Skrabec1-4/+3
SRAM driver often returns -EPROBE_DEFER and thus this bus driver often prints error message, even if it probes successfully later. This is confusing for users and they often think that something is wrong. Use dev_err_probe() helper for printing error message. It handles -EPROBE_DEFER automatically.
