Subject: ARM: dts: sun5i: q8-common: Enable audio codec
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=dddc8e0b4c6b865c259fd012818f2212af8721dc;p=openwrt%2Fstaging%2Fblogic.git

ARM: dts: sun5i: q8-common: Enable audio codec

The Q8 tablets use the audio codec to provide audio output via a
headphone jack or a small mono speaker. A GPIO output is used to
control speaker amp.

The tablets may or may not have an internal microphone.
