Merge tag 'arm-soc-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC updates from Arnd Bergmann:
"The majority of the changes are for the OMAP2 platform, mostly
removing some dead code that got left behind from previous cleanups.
Aside from that, there are very minor updates and correctness fixes
for Zynq, i.MX, Samsung, Broadcom, AT91, ep93xx, and OMAP1"
