Merge tag 'soc-fixes-5.14-3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC fixes from Arnd Bergmann: "Not much to see here. Half the fixes this time are for Qualcomm dts files, fixing small mistakes on certain machines. The other fixes are: - A 5.13 regression fix for freescale QE interrupt controller\ - A fix for TI OMAP gpt12 timer error handling - A randconfig build regression fix for ixp4xx - Another defconfig fix following the CONFIG_FB dependency rework" * tag 'soc-fixes-5.14-3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: soc: fsl: qe: fix static checker warning ARM: ixp4xx: fix building both pci drivers ARM: configs: Update the nhk8815_defconfig bus: ti-sysc: Fix error handling for sysc_check_active_timer() soc: fsl: qe: convert QE interrupt controller to platform_device arm64: dts: qcom: sdm845-oneplus: fix reserved-mem arm64: dts: qcom: msm8994-angler: Disable cont_splash_mem arm64: dts: qcom: sc7280: Fixup cpufreq domain info for cpu7 arm64: dts: qcom: msm8992-bullhead: Fix cont_splash_mem mapping arm64: dts: qcom: msm8992-bullhead: Remove PSCI arm64: dts: qcom: c630: fix correct powerdown pin for WSA881x
