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.

Thanks applying all for v5.15 merge window.

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

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.

OK thanks for checking.
