Subject: [PATCH v5 5/5] ARM: dts: bcm2837-rpi-3-b: add GPIO expander
Date: Tue, 20 Feb 2018 14:19:35 +0200	[thread overview]
Message-ID: <a6d59692dc4847e0b1639a26542e28c95ad5240f.1519128054.git.baruch@tkos.co.il> (raw)
In-Reply-To: <cover.1519128054.git.baruch@tkos.co.il>

Add a description of the RPi3 GPIO expander that the VC4 firmware controls.

Acked-by: Stefan Wahren <stefan.wahren@i2se.com>
Signed-off-by: Baruch Siach <baruch@tkos.co.il>

v5:
  * Drop the 'firmware' property

v4:
  * Move the gpio node under the firmware node
  * Rename the gpio node to plain 'gpio'
  * Add Stefan's ack

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
