Pull ARM driver updates from Arnd Bergmann: "There are minor updates to SoC specific drivers for chips by Rockchip, Samsung, NVIDIA, TI, NXP, i.MX, Qualcomm, and Broadcom. Noteworthy driver changes include: - Several conversions of DT bindings to yaml format. - Renesas adds driver support for R-Car V4H, RZ/V2M and RZ/G2UL SoCs. - Qualcomm adds a bus driver for the SSC (Snapdragon Sensor Core), and support for more chips in the RPMh power domains and the soc-id. - NXP has a new driver for the HDMI blk-ctrl on i.MX8MP. - Apple M1 gains support for the on-chip NVMe controller, making it possible to finally use the internal disks. This also includes SoC drivers for their RTKit IPC and for the SART DMA address filter. For other subsystems that merge their drivers through the SoC tree, we have - Firmware drivers for the ARM firmware stack including TEE, OP-TEE, SCMI and FF-A get a number of smaller updates and cleanups. OP-TEE now has a cache for firmware argument structures as an optimization, and SCMI now supports the 3.1 version of the specification. - Reset controller updates to Amlogic, ASpeed, Renesas and ACPI drivers - Memory controller updates for Tegra, and a few updates for other platforms" * tag 'arm-drivers-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (159 commits) memory: tegra: Add MC error logging on Tegra186 onward memory: tegra: Add memory controller channels support memory: tegra: Add APE memory clients for Tegra234 memory: tegra: Add Tegra234 support nvme-apple: fix sparse endianess warnings soc/tegra: pmc: Document core domain fields soc: qcom: pdr: use static for servreg_* variables soc: imx: fix semicolon.cocci warnings soc: renesas: R-Car V3U is R-Car Gen4 soc: imx: add i.MX8MP HDMI blk-ctrl soc: imx: imx8m-blk-ctrl: Add i.MX8MP media blk-ctrl soc: imx: add i.MX8MP HSIO blk-ctrl soc: imx: imx8m-blk-ctrl: set power device name soc: qcom: llcc: Add sc8180x and sc8280xp configurations dt-bindings: arm: msm: Add sc8180x and sc8280xp LLCC compatibles soc/tegra: pmc: Select REGMAP dt-bindings: reset: st,sti-powerdown: Convert to yaml dt-bindings: reset: st,sti-picophyreset: Convert to yaml dt-bindings: reset: socfpga: Convert to yaml dt-bindings: reset: snps,axs10x-reset: Convert to yaml ...

memory: tegra: Add MC error logging on Tegra186 onward

2022-05-09T08:46:14Z

Add support for logging memory controller errors on Tegra186, Tegra194 and Tegra234. On these SoCs, interrupts can occur on multiple channels. Add support required to read the status of interrupts across multiple channels, log and clear them. Also add new interrupts supported on these SoCs.

memory: tegra: Add memory controller channels support

2022-05-09T08:46:11Z

From Tegra186 onwards, the memory controller supports multiple channels. Add support for mapping the address spaces of these channels and specify the number of channels supported by Tegra186, Tegra194 and Tegra234. In case of old bindings, channels won't be present. If channels are not present then print a warning and continue so that backward compatibility will be preserved in driver. During error interrupts from memory controller, appropriate registers from these channels need to be accessed for logging error info.

The memory controller and external memory controller found on Tegra234 is similar to the version found on earlier SoCs but supports a number of new memory clients. Add initial memory client definitions for the Tegra234 so that the SMMU stream ID override registers can be properly programmed at boot time.

memory: omap-gpmc: Allow building as a module

2022-04-29T06:57:36Z

Allow OMAP_GPMC to be built as a module. When building this driver as a module, the symbol 'of_default_bus_match_table' will not be found as it is not being exported. The of_match_node() call is redundant anyways as of_platform_default_populate() already takes care of matching with 'of_default_bus_match_table'. So get rid of that call. This will also resolve the module build failure. Move compatible match table to the end where it is usually expected.
