Subject: [PATCH] ARM: dts: ux500: Add Flash LEDs to Samsung phones
Date: Mon, 1 Feb 2021 10:13:08 +0100 [thread overview]
Message-ID: <20210201091308.284465-1-linus.walleij@linaro.org> (raw)
This adds the Richtek RT8515 Flash LED to the Golden,
Skomer and Janice device trees.
Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
---
SoC folks: please merge this on the appropriate branch for
v5.12, we got this driver and bindings merged so it's nice
to add this support in the next merge window.
