Subject: [PATCH 1/1] arm64: dts: renesas: eagle: add I2C0 support
Date: Thu, 16 Nov 2017 23:56:48 +0300 [thread overview]
Message-ID: <20171116210312.016087689@cogentembedded.com> (raw)
[-- Attachment #1: arm64-dts-renesas-eagle-add-I2C0-support.patch --]
[-- Type: text/plain, Size: 1554 bytes --]
Define the Eagle board dependent part of the I2C0 device node.
The I2C0 bus is populated by ON Semiconductor PCA9653 I/O expander and
Analog Devices ADV7511W HDMI transmitter (but we're only describing the
former chip now).
Based on the original (and large) patch by Vladimir Barinov.
