From: sergei.shtylyov@cogentembedded.com (Sergei Shtylyov) Date: Fri, 17 Nov 2017 00:06:31 +0300 Subject: [PATCH 2/2] arm64: dts: renesas: eagle: add I2C0 support Message-ID: <20171116210801.215014557@cogentembedded.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
