Subject: [PATCH 05/11] ARM: DTS: dra7-evm: Enable pcf8575 (0x26 address) on i2c2 bus
Date: Mon, 24 Aug 2015 10:20:01 +0300	[thread overview]
Message-ID: <1440400807-32274-6-git-send-email-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <1440400807-32274-1-git-send-email-peter.ujfalusi@ti.com>

This GPIO expander is used for controlling various muxes on the board.
By default select audio functionality over VIN6 by setting the P1
(vin6_sel_s0) pin to low.
