Subject[PATCH v9 0/2] sun4i-codec: Add Line-In, FM-In, Mic 2, Capture Source, Differential Line-In
Message-ID<sbK5P-Fr-3@gated-at.bofh.it>
This patch adds support for some mixer controls:
 - Line-In
 - FM-In
 - Mic 2
 - Capture Source
 - Differential Line-In

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.

Danny Milosavljevic (2):
  ASoC: sun4i-codec: Distinguish sun4i from sun7i
  Add mixer controls: Line-In, FM-In, Mic 2, Capture Source,
    Differential Line-In.

In reply to#1472234
This distinguishes sun4i from sun7i. It is necessary because they use
different registers for the audio mixer.

This is slightly worrying. It will get messy as you add more widgets.

On sun4i the registers only go as far as SUN4I_CODEC_ADC_RXCNT.
Could you add a separate regmap_config as well?

This will get reworked into something like in

https://github.com/wens/linux/commit/54a58e3087fb67572ca416256bc000e08b163480

I haven't gotten around to posting this series yet though.

That will need at least some mention in the commit log.

You need a new line here.

It would be better to add a structure assiocated to the data field of
of_device_id. That way, you'll also be able to have any quirks without
adding more checks (such as a different regmap config, like Chen-Yu
suggested).

Thanks!

Hm? It's now called like it is called in the user manual.
Also, the macro SUN4I_CODEC_AC_SYS_VERI was unused before anyway.

What should I write in the commit log?

Yeah, I did that now; seems to work.

For example, that the current code was wrong and those registers are
not present on the A10.

That way, you justify both the renaming, and the max_register change
in the regmap.
