Subject: [PATCH v2] arm64: dts: renesas: falcon-cpu: Add GP LEDs
Date: Mon, 22 Mar 2021 17:20:13 +0000	[thread overview]
Message-ID: <20210322172013.1152121-1-kieran.bingham+renesas@ideasonboard.com> (raw)

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.

Signed-off-by: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com>

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