[PATCH v15 0/8] ASoC: sun4i-codec: Add Line-In, FM-In, Mic 2

[Danny Milosavljevic]

This patchset adds some mixer controls to sun4i-codec for the Allwinner A10
and the Allwinner A20.

It also adds 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.

v15 changes compared to v14 are:
 - Instead of adding controls dynamically, add an extra sun7i_codec_controls
   structure and duplicate the sun4i_codec_controls there, with small changes.
 - Split Mic Playback Volume into extra patch.
 - LEFT OFF adding Capture Selects since it's unclear how we want to structure
   it.
 - LEFT OFF adding Differential Line Source since it might also change if the
   Capture Select implementation is different.

v14 changes compared to v13 are:
 - Merged some of the patches together if it made sense to test them together.
 - Use snd_soc_component_driver.
 - Moved SUN4I_CODEC_DAC_ACTL_LFMS, SUN4I_CODEC_DAC_ACTL_RFMS to the correct
   patch in the series.
 - Kept "Left Mixer Left DAC Playback Switch", "Right Mixer Left DAC
   Playback Switch" and "Right Mixer Right DAC Playback Switch" unchanged
   compared to the released version - for backward compatibility.

v13 changes compared to v12 are:
 - Added my "Signed-off-by".
 - Clarified some commit message text.

v12 changes compared to v11 are:
 - Split up patchset in another way.
 - Renamed "Mic1 Capture Volume" to "Mic1 Boost Volume".
 - Renamed "Mic2 Capture Volume" to "Mic2 Boost Volume".
 - Renamed "Line Capture Volume" to "Line Boost Volume".
 - Renamed "Differential Line Capture Switch" to "Differential Line Source".

v11 changes compared to v10 are:
 - Split up patchset.
 - Fixed typo in Differential Line Capture Switch.
 - Renamed "Non-Differential" value to "Stereo".
 - Removed duplicate PA Volume mixer control.

v10 changes compared to v9 are:
 - Use SOC_DAPM_DOUBLE where possible and it makes sense in order to cut
   down on the number of controls.

v9 changes compared to v8 are:
 - added Line Differential Capture Switch.
 - split Capture Source into Left Capture Select, Right Capture Select.
 - added Line Capture Volume.
 - rename "sun4i_codec_widgets" to "sun4i_codec_controls" for
   consistency with the struct field it's used in.
 - rename "Line-In" to "Line".
 - rename "Power Amplifier Playback Volume" to "Headphone Playback Volume".

v8 changes compared to v7 are:
 - fixed the routes for line and mic capturing.

v7 changes compared to v6 are:
 - preparation for different A20, A10 controls is now in an extra patch.
 - all register definitions are now at the top.
 - sun7i-specific things (A20-specific things) are now less
   grouped-together.
 - rename "Power Amplifier Volume" to "Power Amplifier Playback Volume".

v6 changes compared to v5 are:
 - Mic preamplifier special cases for A20 and A10 now are now not
   icky: There are two different _widget arrays and the probe() function
   now selects the right one to pass to snd_soc_register_codec() unmodified.
 - sun7i-specific things (A20-specific things) are now grouped together.

v5 changes compared to v4 are:
 - Mic preamplifier controls have more common names now.
 - Mic preamplifier scale has a 0 dB entry as well now, as documented in the
   A20 user manual.
 - Mic preamplifier has special cases for A20 and A10 now.
 - Gain controls have "Gain" in the name now.

v4 changes compared to v3 are:
 - names of the input are not uppercase anymore.
 - bit index constants are now named as in the A20 user manual v1.4.
 - added Mic1-In, Mac2-In.
 - added Mic1 and Mic2 Pre-Amplifiers.

v3 changes compared to v2 are:
 - added DAPM routes.

v2 changes compared to v1 are:
 - moved Line-In and FM-In playback switches to their respective
   sun4i_codec_*_mixer_controls.

v1 changes:
 - added linein, fmin output volumes and switches.
