Merge tag 'arm-drivers-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC driver updates from Arnd Bergmann: "Updates for SoC specific drivers include a few subsystems that have their own maintainers but send them through the soc tree: SCMI firmware: - add support for a completion interrupt Reset controllers: - new driver for BCM4908 - new devm_reset_control_get_optional_exclusive_released() function Memory controllers: - Renesas RZ/G2 support - Tegra124 interconnect support - Allow more drivers to be loadable modules TEE/optee firmware: - minor code cleanup The other half of this is SoC specific drivers that do not belong into any other subsystem, most of them living in drivers/soc: - Allwinner/sunxi power management work - Allwinner H616 support - ASpeed AST2600 system identification support - AT91 SAMA7G5 SoC ID driver - AT91 SoC driver cleanups - Broadcom BCM4908 power management bus support - Marvell mbus cleanups - Mediatek MT8167 power domain support - Qualcomm socinfo driver support for PMIC - Qualcomm SoC identification for many more products - TI Keystone driver cleanups for PRUSS and elsewhere" * tag 'arm-drivers-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (89 commits) soc: aspeed: socinfo: Add new systems soc: aspeed: snoop: Add clock control logic memory: tegra186-emc: Replace DEFINE_SIMPLE_ATTRIBUTE with DEFINE_DEBUGFS_ATTRIBUTE memory: samsung: exynos5422-dmc: Correct function names in kerneldoc memory: ti-emif-pm: Drop of_match_ptr from of_device_id table optee: simplify i2c access drivers: soc: atmel: fix type for same7 tee: optee: remove need_resched() before cond_resched() soc: qcom: ocmem: don't return NULL in of_get_ocmem optee: sync OP-TEE headers tee: optee: fix 'physical' typos drivers: optee: use flexible-array member instead of zero-length array tee: fix some comment typos in header files soc: ti: k3-ringacc: Use of_device_get_match_data() soc: ti: pruss: Refactor the CFG sub-module init soc: mediatek: pm-domains: Don't print an error if child domain is deferred soc: mediatek: pm-domains: Add domain regulator supply dt-bindings: power: Add domain regulator supply soc: mediatek: cmdq: Remove cmdq_pkt_flush() soc: mediatek: pm-domains: Add support for mt8167 ...
