bc03f0d576 ASoC: sun4i-codec: Expand quirks to handle register offsets and card creation
The A31 has a similar codec to the A10/A20. The PCM parts are very
similar, with just different register offsets. The analog paths are
very different. There are more inputs and outputs.

The A31s, A23, and H3 have a similar PCM interface, again with register
offsets slightly rearranged. The analog path controls, while very
similar between them and the A31, have been moved a separate bus which
is accessed through a message box like interface in the PRCM address
range. This would be handled by a separate auxiliary device tied in
through the device tree in its supporting create_card function.

The quirks structure is expanded to include different register offsets
and separate callbacks for creating the ASoC card. The regmap_config,
quirks, and of_device_match tables have been moved to facilitate this.

2f2a3462bc ASoC: sun4i-codec: Move data structures to add create_card call to quirks
The audio codec on later Allwinner SoCs have a different layout and
audio path compared to the A10/A20. However the PCM parts are still
the same.

The different layout and audio paths mean we need a different
create_card function for different families, so they can create
DAPM endpoint widgets and routes.

This patch moves the regmap configs, quirks and of_device_id
structures to just before the probe function, so we can, among other
things, include a pointer for the create_card function. None of the
lines of code were changed.

3716a891d6 ASoC: sun4i-codec: Enable bus clock after getting GPIO
In the current probe function the GPIO is acquired after the codec's
bus clock is enabled. However if it fails to acquire the GPIO due to
a deferred probe, it does not disable the bus clock before bailing out.
This would result in the clock being enabled multiple times.

Move the code that enables the bus clock after the part that gets the
GPIO, maintaining a separation between resource acquisition and device
enablement in the probe function.

85915b63ad ASoC: sun4i-codec: return error code instead of NULL when create_card fails
When sun4i_codec_create_card fails, we do not assign a proper error
code to the return value. The return value would be 0 from the previous
function call, or we would have bailed out sooner. This would confuse
the driver core into thinking the device probe succeeded, when in fact
it didn't, leaving various devres based resources lingering.

Make the create_card function pass back a meaningful error code, and
assign it to the return value.

180f58fece ASoC: codec duplicated callback function goes to component on sun4i-codec
codec driver and component driver has duplicated callback functions,
and codec side functions are just copied to component side when
register timing. This was quick-hack, but no longer needed.
This patch moves these functions from codec driver to component driver.

474d147ad1 ASoC: sun4i-codec: use consistent names for PA controls
The power amplifier for the headphone output is called "the PA" and "the
headphone amplifier" in Allwinner's documentation for the A10 and A20.
sun4i-codec calls it "PA" in some places and "Pre-Amplifier" (which
isn't really accurate) in others, leading to user-visible controls with
different names referring to the same device.

When this driver implements audio input, it'll also need to expose
controls for the line and mic input preamps, so just referring to "the
Pre-Amplifier" will be ambiguous.

Change it to use "Power Amplifier" consistently for the power
amplifier's controls.

c570b82c5e ASoC: sun4i-codec: Remove the routing property
Most of the boards have their headphone jack directly connected to the
matching pins of the SoCs. Since most of the time we will have the same
routing path, it makes no sense to put that in the DTS, since it will only
be some useless duplication there.

It also fixes the following warning messages that were seen so far, on
boards where we were using the bindings in the documentation example.

45fb6b6f2a ASoC: sunxi: add support for the on-chip codec on early Allwinner SoCs
The sun4i, sun5i and sun7i SoC families have a built-in codec, capable
of both audio capture and playback.

While this is called a codec by Allwinner, it really is an in-SoC
combination of a codec and a DAI, with its own DAC/ADC and amplifiers
in a single memory-mapped controller.

The capture part has been left out for now, and will be added eventually.
