Merge tag 'devicetree-fixes-for-5.15-2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree fixes from Rob Herring:
- Revert fw_devlink tracking 'phy-handle' links. This broke at least a
few platforms. A better solution is being worked on.
- Add Samsung UFS binding which fell thru the cracks
- Doc reference fixes from Mauro
- Fix for restricted DMA error handling
