Subject: arm64: dts: mcbin-singleshot: add heartbeat LED
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=da57203dc7fd556fbb3f0ec7d7d7c0b0e893b386;p=linux.git

arm64: dts: mcbin-singleshot: add heartbeat LED

With board revision 1.3, SolidRun moved the power LED to the middle of
the board. In old place of power LED a GPIO controllable heartbeat LED
was added. This commit only touches Single Shot variant, since only this
variant is all revision 1.3.
