Hans de Goede 6b803c611c ASoC: sun4i-codec: Use proper output for external amp routes
An external amp (if any) is connected to the external outputs of the SoC
of course, rather then directly to the internal amp.

Hans de Goede e6415b4850 ASoC: sun4i-codec: Rename codec dapm widgets and routes
Rename the codec dapm widgets and routes with a _codec prefix. This is
a preparation patch for adding card dapm widgets and routes.

Maxime Ripard 8400ddf4ac ASoC: sun4i-codec: pass through clk_set_rate error
Commit 1fb34b4836 ('ASoC: sun4i: Implement MIC1 capture') added back some
code that disregards the clk_set_rate error code and always returns
-EINVAL. Fix that and return the code in order to have more clue about
what's going on.

Maxime Ripard 0837d8780c ASoC: sunxi: Remove useless comments and variable
The comment is misleading on how we should support external power amps, and
the variable is not used and generates a warning.

One of the input path used in the Allwinner codec is the MIC1. Add support

Adam Sampson 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.

Maxime Ripard 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.

sun4i-codec 1c22c00.codec: ASoC: no sink widget found for Headphone Jack
sun4i-codec 1c22c00.codec: ASoC: Failed to add route HP Left -> direct -> Headphone Jack
sun4i-codec 1c22c00.codec: ASoC: no sink widget found for Headphone Jack

Emilio López 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.
