Subject: [PATCH] arm64: dts: sun50i-pinephone: add led flash
Date: Sat, 25 Jul 2020 13:08:12 +0200	[thread overview]
Message-ID: <20200725110812.199529-1-luca@z3ntu.xyz> (raw)

All revisions of the PinePhone have an SGM3140 LED flash. The gpios were
swapped on v1.0 of the board but this was fixed in later revisions.
