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" * tag 'arm-drivers-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (149 commits) ARM: remove check for CONFIG_DEBUG_LL_SER3 firmware/psci: Add debugfs support to ease debugging firmware/psci: Print a warning if PSCI doesn't accept PC mode dt-bindings: memory: snps,dw-umctl2-ddrc: Extend schema with IRQs/resets/clocks props dt-bindings: memory: snps,dw-umctl2-ddrc: Replace opencoded numbers with macros dt-bindings: memory: snps,dw-umctl2-ddrc: Use more descriptive device name dt-bindings: memory: synopsys,ddrc-ecc: Detach Zynq DDRC controller support soc: sunxi: sram: Add support for the D1 system control soc: sunxi: sram: Export the LDO control register soc: sunxi: sram: Save a pointer to the OF match data soc: sunxi: sram: Return void from the release function soc: apple: rtkit: Add apple_rtkit_poll soc: imx: add i.MX93 media blk ctrl driver soc: imx: add i.MX93 SRC power domain driver soc: imx: imx8m-blk-ctrl: Use genpd_xlate_onecell soc: imx: imx8mp-blk-ctrl: handle PCIe PHY resets soc: imx: imx8m-blk-ctrl: add i.MX8MP VPU blk ctrl soc: imx: add i.MX8MP HDMI blk ctrl HDCP/HRV_MWR soc: imx: add icc paths for i.MX8MP hsio/hdmi blk ctrl soc: imx: add icc paths for i.MX8MP media blk ctrl ...
