Merge tag 'soc-fixes-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC DT and driver fixes from Arnd Bergmann: "Lots of dts fixes for Qualcomm Snapdragon and NXP i.MX platforms, including: - A regression fix for SDHCI controllers on Inforce 6540, and another SDHCI fix on SM8350 - Reenable cluster idle on sm8250 after the the code fix is upstream - multiple fixes for the QMP PHY binding, needing an incompatible dt change - The reserved memory map is updated on Xiaomi Mi 4C and Huawei Nexus 6P, to avoid instabilities caused by use of protected memory regions - Fix i.MX8MP DT for missing GPC Interrupt, power-domain typo and USB clock error - A couple of verdin-imx8mm DT fixes for audio playback support - Fix pca9547 i2c-mux node name for i.MX and Vybrid device trees - Fix an imx93-11x11-evk uSDHC pad setting problem that causes Micron eMMC CMD8 CRC error in HS400ES/HS400 mode The remaining ARM and RISC-V platforms only have very few smaller dts bugfixes this time: - A fix for the SiFive unmatched board's PCI memory space - A revert to fix a regression with GPIO on Marvell Armada - A fix for the UART address on Marvell AC5 - Missing chip-select phandles for stm32 boards - Selecting the correct clock for the sam9x60 memory controller - Amlogic based Odroid-HC4 needs a revert to restore USB functionality. And finally, there are some minor code fixes: - Build fixes for OMAP1, pxa, riscpc, raspberry pi firmware, and zynq firmware - memory controller driver fixes for an OMAP regression and older bugs on tegra, atmel and mvebu - reset controller fixes for ti-sci and uniphier platforms - ARM SCMI firmware fixes for a couple of rare corner cases - Qualcomm platform driver fixes for incorrect error handling and a backwards compatibility fix for the apr driver using older dtb - NXP i.MX SoC driver fixes for HDMI output, error handling in the imx8 soc-id and missing reference counting on older cpuid code" * tag 'soc-fixes-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (60 commits) firmware: zynqmp: fix declarations for gcc-13 ARM: dts: stm32: Fix qspi pinctrl phandle for stm32mp151a-prtt1l ARM: dts: stm32: Fix qspi pinctrl phandle for stm32mp157c-emstamp-argon ARM: dts: stm32: Fix qspi pinctrl phandle for stm32mp15xx-dhcom-som ARM: dts: stm32: Fix qspi pinctrl phandle for stm32mp15xx-dhcor-som ARM: dts: at91: sam9x60: fix the ddr clock for sam9x60 ARM: omap1: fix building gpio15xx ARM: omap1: fix !ARCH_OMAP1_ANY link failures firmware: raspberrypi: Fix type assignment arm64: dts: qcom: msm8992-libra: Fix the memory map arm64: dts: qcom: msm8992: Don't use sfpb mutex PM: AVS: qcom-cpr: Fix an error handling path in cpr_probe() arm64: dts: msm8994-angler: fix the memory map arm64: dts: marvell: AC5/AC5X: Fix address for UART1 ARM: footbridge: drop unnecessary inclusion Revert "ARM: dts: armada-39x: Fix compatible string for gpios" Revert "ARM: dts: armada-38x: Fix compatible string for gpios" ARM: pxa: enable PXA310/PXA320 for DT-only build riscv: dts: sifive: fu740: fix size of pcie 32bit memory soc: qcom: apr: Make qcom,protection-domain optional again ...
