Subject: [PATCH v3 4/4] ARM: dts: bcm2837-rpi-3-b: add GPIO expander
Date: Tue, 16 Jan 2018 14:45:10 +0200 [thread overview]
Message-ID: <8ba2147dc08bb50a65b49ca2142f7710e1635d20.1516105893.git.baruch@tkos.co.il> (raw)
In-Reply-To: <cover.1516105893.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>
---
v3:
* List GPIO names one per line.
v2:
* Move GPIO expander node out of the soc container
* Rename compatible string
* Add gpio-line-names property
