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"
