Stephen / Michael, would it be possible to schedule these patches for 4.16? My
T20 and T30 devices aren't working without the 'critical clocks' patch. Things
happen to work with the opensource u-boot, but not with the proprietary
bootloader. It's probably not a big deal that out-of-tree devices are broken,
although would be nice to have one problem less.
