Subject: [PATCH] ARM: dts: aspeed: cmm: enable iio-hwmon-adc
Date:   Tue, 5 Feb 2019 14:46:19 -0800
Message-ID: <20190205224619.2102873-1-taoren@fb.com>
MIME-Version: 1.0
Content-Type: text/plain
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Bind aspeed ADC channels 0-7 to "iio-hwmon" driver so the data of these
voltage sensing channels can be accessed by "lm_sensors". Channels 8-15
are not used on CMM BMC.
