-Subject: [PATCH 110/114] BCM270x_DT: Add pwr_led, and the required "input"
- trigger
-
-The "input" trigger makes the associated GPIO an input. This is to support
-the Raspberry Pi PWR LED, which is driven by external hardware in normal use.
-
-N.B. pwr_led is not available on Model A or B boards.
