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