Subject: [PATCH v2 5/5] arm64: dts: mt7986: add overlay for SATA power socket on BPI-R3
Date: Wed, 25 Oct 2023 19:08:32 +0200	[thread overview]
Message-ID: <20231025170832.78727-6-linux@fw-web.de> (raw)
In-Reply-To: <20231025170832.78727-1-linux@fw-web.de>

From: Frank Wunderlich <frank-w@public-files.de>

Bananapi R3 has a Power socket entended for using external SATA drives.
This Socket is off by default but can be switched with gpio 8.

Add an overlay to activate it.

Signed-off-by: Frank Wunderlich <frank-w@public-files.de>

v2:
- rebase on the patch "add dtbs with applied overlays for bpi-r3"
- add sata-overlay to the full dtbs
