Subject: [PATCH v2 4/4] ARM: dts: bcm2837-rpi-3-b: add GPIO expander
Date: Thu, 11 Jan 2018 21:44:27 +0200 [thread overview]
Message-ID: <1cb81e3d7a1b1f7ccf374952fa7e8d2147c186fb.1515698418.git.baruch@tkos.co.il> (raw)
In-Reply-To: <cover.1515698418.git.baruch@tkos.co.il>
Add a description of the RPi3 GPIO expander that the VC4 firmware controls.
Signed-off-by: Baruch Siach <baruch@tkos.co.il>
