Merge tag 'arm-drivers-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM driver updates from Arnd Bergmann:
"The drivers branch for 6.1 is a bit larger than for most releases.
Most of the changes come from SoC maintainers for the drivers/soc
subsystem:
- A new driver for error handling on the NVIDIA Tegra 'control
backbone' bus.
- A new driver for Qualcomm LLCC/DDR bandwidth measurement
- New Rockchip rv1126 and rk3588 power domain drivers
- DT binding updates for memory controllers, older Rockchip SoCs,
various Mediatek devices, Qualcomm SCM firmware
- Minor updates to Hisilicon LPC bus, the Allwinner SRAM driver, the
Apple rtkit firmware driver, Tegra firmware
- Minor updates for SoC drivers (Samsung, Mediatek, Renesas, Tegra,
Qualcomm, Broadcom, NXP, ...)
There are also some separate subsystem with downstream maintainers
that merge updates this way:
- Various updates and new drivers in the memory controller subsystem
for Mediatek and Broadcom SoCs
- Small set of changes in preparation to add support for FF-A v1.1
specification later, in the Arm FF-A firmware subsystem
- debugfs support in the PSCI firmware subsystem"
