I tested the for-next branch of linux-omap to confirm that things worked with these patches applied. There was a NULL pointer dereference in ptp_clock_register() during boot. The fix appears to be https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=55eac20617ca84129273ab248f4d7bfe456967de which went into 5.14-rc2. Merging for-next with 5.14-rc4 resulted in things working as expected.

Yeah so it seems, too bad it was not there for -rc1 already. > Merging for-next with 5.14-rc4 resulted in things working as expected. OK thanks for checking. Regards, Tony
The Lite variant of the SanCloud BeagleBone Enhanced (BBE) removes the HDMI encoder, barometer and accelerometer chips and adds a Micron Authenta SPI flash chip. The device tree entries shared with the original BBE and the BegleBone Black are refactored to avoid unnecessary duplication and avoid having to override the status of nodes to "disabled" in any of the dts files. The final patch in this series adds myself and Marc from Sancloud as maintainers for the device trees for SanCloud hardware. We're happy to review any future patches to these files so that the SanCloud boards work well with the mainline kernel. We expect the patch volume to be pretty low and we expect that patches to these files will flow upstream via the existing OMAP device tree maintainers and linux-omap mailing list. If there's anything else we need to do to adopt these dts files as supported please let us know. Changes from v1: * Dropped symlink property from the spi channel node, this isn't needed outside of the BeagleBoard.org tree as pointed out by Robert Nelson.
