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 ...

bus: mhi: host: always print detected modem name

2022-09-16T08:08:25Z

This harmless print provides a very easy way of knowing if the modem is detected properly during probing. Promote it to an informational print so no hassle is required enabling kernel debugging info to obtain it. The rationale here is that: On a lot of low-storage embedded devices, extensive kernel debugging info is not always present as this would increase it's size to much causing partition size issues.

bus: hisi_lpc: Use platform_device_register_full()

The code to create the child platform device is essentially the same as what platform_device_register_full() does, so change over to use that same function to reduce duplication. Signed-off-by: John Garry Suggested-by: Andy Shevchenko Reviewed-by: Andy Shevchenko Signed-off-by: Wei Xu

bus: hisi_lpc: Don't guard ACPI IDs with ACPI_PTR()

The OF ID table is not guarded, and the ACPI table does not needs it either. The IDs do not depend on the configuration. Hence drop ACPI_PTR() from the code and move ID table closer to its user.
