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"
