Merge tag 'soc-fixes-6.1-4' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC fixes from Arnd Bergmann:
"There are a bunch of late fixes that just came in, in particular a
longer series for Rockchips devicetree files, but most of those just
address cosmetic errors that were found during the binding validation.
There are a couple of code changes:
- A regression fix to the IXP42x PCI bus
- A fix for a memory leak on optee, and another one for mach-mxs
- Two fixes for the sunxi rsb bus driver, to address problems with
the shutdown logic
The rest are small but important devicetree fixes for a number of
individual boards, addressing issues across all platforms:
- arm global timer on older rockchip SoCs is unstable and needs to be
disabled in favor of a more reliable clocksource
- Corrections to fix bluetooth, mmc, and networking on a few Rockchip
boards
- at91/sam9g20ek UDC needs a pin controller config change
- an omap board runs into mmc probe errors because of regulator nodes
in the wrong place
- imx8mp-evk has a minor inaccuracy with its pin config, but without
user visible impact
- The Allwinner H6 Hantro G2 video decoder needs an IOMMU reference
to prevent the driver from crashing"
