Subject: [PATCH v10] sun4i-codec: Add mixer controls: Line-In, FM-In, Mic 2, Capture Source, Differential Line-In.
Adds support for some mixer controls to sun4i-codec:
- Line-In
- FM-In
- Mic 2
- Capture Source
- Differential Line-In
It also adds a mux for the capture source and the PGA for the MIC2 preamp.
Where possible, it uses SOC_DAPM_DOUBLE in order to cut down on the number
of distinct controls in alsamixer.
