Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC fixes from Olof Johansson: "A slightly larger set of fixes have accrued in the last two weeks. Mostly a collection of the usual smaller fixes: - Marvell Armada: USB phy setup issues on Turris Mox - Broadcom: GPIO/pinmux DT mapping corrections for Stingray, MMC bus width fix for RPi Zero W, GPIO LED removal for RPI CM3. Also some maintainer updates. - OMAP: Fixlets for display config, interrupt settings for wifi, some clock/PM pieces. Also IOMMU regression fix and a ti-sysc no-watchdog regression fix. - i.MX: A few fixes around PM/settings, some devicetree fixlets and catching up with config option changes in DRM - Rockchip: RockRro64 misc DT fixups, Hugsun X99 USB-C, Kevin display panel settings ... and some smaller fixes for Davinci (backlight, McBSP DMA), Allwinner (phy regulators, PMU removal on A64, etc)" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (42 commits) ARM: dts: stm32: relax qspi pins slew-rate for stm32mp157 MAINTAINERS: Update the Spreadtrum SoC maintainer MAINTAINERS: Remove Gregory and Brian for ARCH_BRCMSTB ARM: dts: bcm2837-rpi-cm3: Avoid leds-gpio probing issue bus: ti-sysc: Fix watchdog quirk handling ARM: OMAP2+: Add pdata for OMAP3 ISP IOMMU ARM: OMAP2+: Plug in device_enable/idle ops for IOMMUs ARM: davinci_all_defconfig: enable GPIO backlight ARM: davinci: dm365: Fix McBSP dma_slave_map entry ARM: dts: bcm2835-rpi-zero-w: Fix bus-width of sdhci ARM: imx_v6_v7_defconfig: Enable CONFIG_DRM_MSM arm64: dts: imx8mn: Use correct clock for usdhc's ipg clk arm64: dts: imx8mm: Use correct clock for usdhc's ipg clk arm64: dts: imx8mq: Use correct clock for usdhc's ipg clk ARM: dts: imx7s: Correct GPT's ipg clock source ARM: dts: vf610-zii-scu4-aib: Specify 'i2c-mux-idle-disconnect' ARM: dts: imx6q-logicpd: Re-Enable SNVS power key arm64: dts: lx2160a: Correct CPU core idle state name mailmap: Add Simon Arlott (replacement for expired email address) arm64: dts: rockchip: Fix override mode for rk3399-kevin panel ...
