Subject: [PATCH] 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.
|
||
|
|
|
||
|
|
Note:
|
||
|
|
This is slightly modified patch. Some boards could be placed in an
|
||
|
|
enclosure, so the LED18 is enabled by default, since that'll be the only
|
||
|
|
visible indicator that the board is operating.
