Qualcomm driver updates for v5.16 This drops the use of power-domains for exposing the load_state from the QMP driver to clients, to avoid issues related to system suspend. SMP2P becomes wakeup capable, to allow dying remoteprocs to wake up Linux from suspend to perform recovery. It adds RPM power-domain support for SM6350 and MSM8953 and base RPM support for MSM8953 and QCM2290. It adds support for MSM8996, SDM630 and SDM660 in the SPM driver, which will enable the introduction of proper voltage scaling of the CPU subsystem. 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() ...
