Subject: [PATCH][v2] ARM: dts: exynos: add flash support to galaxy-s3 boards
Date: Tue, 18 Jun 2019 02:17:42 +0200 [thread overview]
Message-ID: <20190618001742.2828-1-GNUtoo@cyberdimension.org> (raw)
In-Reply-To: <20190615170428.GA3447@kozik-lap>
From: Simon Shields <simon@lineageos.org>
The galaxy s3 boards use an aat1290 to control the flash LED.
This patch adds the relevant device tree configuration to use it.
