ARM: dts: am335x-bone*: add DT for BeagleBone Black
Browse files Browse the repository at this point in the history
The BeagleBone Black is basically a regular BeagleBone with eMMC and
HDMI added, so create a common dtsi both can use.

IMPORTANT: booting the existing am335x-bone.dts will blow up the HDMI
transceiver after a dozen boots with an uSD card inserted because LDO
will be at 3.3V instead of 1.8.

MMC support for AM335x still isn't in, so only the LDO change has been
added.
