Bhumika Goyal 92ff5d085e ASoC: sunxi: make snd_soc_codec_driver structures as const
Declare snd_soc_codec_driver structures as const as they are either
passed as an argument to the function snd_soc_register_codec or stored as
reference in field codec of type sun4i_codec_quirks. Both the fucntion
argument and the codec field are of type const, so declare the
structures with this property as const.

Philipp Zabel 72bfa2117b ASoC: sun4i: explicitly request exclusive reset control
Commit a53e35db70 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.

Icenowy Zheng 8b2840b6da ASoC: sun4i-codec: Add support for V3s codec
The codec in the V3s is similar to the one found on the A31. One key
difference is the analog path controls are routed through the PRCM
block. This is supported by the sun8i-codec-analog driver, and tied
into this codec driver with the audio card's aux_dev.

In addition, the V3s does not have LINEIN, LINEOUT, MBIAS and MIC2,
MIC3, and the FIFO related registers are like H3.

Mylène Josserand bf14da7e55 ASoC: sun8i-codec-analog: Add amplifier event to fix first delay
When playing a sound for the first time, a short delay, where the audio
file is not played, can be noticed.
On a second play (right after), the sound is played correctly.
If we wait a short time (~5 sec which corresponds to the aplay
timeout), the delay is back.

This patch fixes it by using an event on headphone amplifier.
It allows to keep the amplifier enable while playing a sound.
A delay of 700ms allows to wait that the amplifier is powered-up
before playing the sound.

Chen-Yu Tsai 730e2dd0cb ASoC: sun4i-codec: Increase DMA max burst to 8
According to the DMA engine API documentation, maxburst denotes the
largest possible size of a single transfer, so as not to overflow
destination FIFOs as explained in this excerpt from dmaengine.h

 * @src_maxburst: the maximum number of words (note: words, as in
 * units of the src_addr_width member, not bytes) that can be sent
 * in one burst to the device. Typically something like half the
 * FIFO depth on I/O peripherals so you don't overflow it. This
 * may or may not be applicable on memory sources.
 * @dst_maxburst: same as src_maxburst but for destination target
 * mutatis mutandis.

The TX FIFO is 64 samples deep for stereo, and the RX FIFO is 16
samples deep. So maxburst could be 32 and 8 for TX and RX respectively.

Unfortunately the sunxi DMA controller driver takes maxburst as
the requested burst size, rather than a limit, and returns an error
for unsupported values. The original value was 4, but some later
SoCs do not officially support this burst size.

This patch increases maxburst on the TX side to 8, which is supported
by all variants of the sunxi DMA controller.

Chen-Yu Tsai 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.

Chen-Yu Tsai 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.

Chen-Yu Tsai 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.

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.

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.
