Subject: [PATCH v2 2/9] ARM: dts: lager: use demuxer for IIC3/I2C3
Date: Sun, 31 Dec 2017 12:23:13 +0100 [thread overview]
Message-ID: <20171231112320.3461-3-wsa+renesas@sang-engineering.com> (raw)
In-Reply-To: <20171231112320.3461-1-wsa+renesas@sang-engineering.com>
Create a separate bus for da9063 PMIC and da9210 regulator
related I2C slaves.
Based on similar work for HDMI by Wolfram Sang.
