[PATCH v2] arm64: dts: renesas: falcon-cpu: Add GP LEDs

From: Kieran Bingham
Date: Mon Mar 22 2021 - 13:21:11 EST


Three general purpose LEDs are provided on the Falcon CPU board.

Connect GP_LED1, GP_LED2, and GP_LED3 to the gpio-leds frameworks as
indicator LEDs.

These LEDs are arranged in a block of four LEDs on the board itself, but
the fourth LED is as yet unidentified.

v2:
- Move to r8a779a0-falcon-cpu.dtsi
- Define the colour, and function.
