Merge tag 'devicetree-fixes-for-5.16-2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull devicetree fixes from Rob Herring:

 - Revert schema checks on %.dtb targets. This was problematic for some
   external build tools.

 - A few DT binding example fixes

 - Add back dropped 'enet-phy-lane-no-swap' Ethernet PHY property

 - Drop erroneous if/then schema in nxp,imx7-mipi-csi2

 - Add a quirk to fix some interrupt controllers use of 'interrupt-map'
