Subject: ASoC: core: Move the default regmap I/O setting to
snd_soc_register_codec()
Add the default regmap I/O setting to snd_soc_register_codec() while
the CODEC is initialising, which will be called by CODEC driver device
probe(), and then we can make XXX_set_cache_io() go away entirely from each
CODEC ASoC probe.

Subject: ASoC: sta350: Add codec driver
The TI STA350 is an integrated 2.1-channel power amplifier that is
controllable over I2C. This patch adds an ASoC driver for it.
At a glance, this chip is very similar to the STA320 for which a driver
already exists. In details, however, the register maps contain subtle
differences which made a whole new driver easier to write and maintain.

+STA350 audio CODEC
+
+The driver for this device only supports I2C.
+
+Required properties:
+
+ - compatible: "st,sta350"
+ - reg: the I2C address of the device for I2C
+ - reset-gpios: a GPIO spec for the reset pin. If specified, it will be
+ deasserted before communication to the codec starts.
+
+ - power-down-gpios: a GPIO spec for the power down pin. If specified,
+ it will be deasserted before communication to the codec
+ starts.
+
+ - vdd-dig-supply: regulator spec, providing 3.3V
+ - vdd-pll-supply: regulator spec, providing 3.3V
+ - vcc-supply: regulator spec, providing 5V - 26V
+
+Optional properties:
+
+ - st,output-conf: number, Selects the output configuration:
+ 0: 2-channel (full-bridge) power, 2-channel data-out
+ 1: 2 (half-bridge). 1 (full-bridge) on-board power
+ 2: 2 Channel (Full-Bridge) Power, 1 Channel FFX
+ 3: 1 Channel Mono-Parallel
+ If parameter is missing, mode 0 will be enabled.
+
+ - st,ch1-output-mapping: Channel 1 output mapping
+ - st,ch2-output-mapping: Channel 2 output mapping
+ - st,ch3-output-mapping: Channel 3 output mapping
+ 0: Channel 1
+ 1: Channel 2
+ 2: Channel 3
+ If parameter is missing, channel 1 is choosen.
+
+ - st,thermal-warning-recover:
+ If present, thermal warning recovery is enabled.
+
+ - st,thermal-warning-adjustment:
+ If present, thermal warning adjustment is enabled.
+
+ - st,fault-detect-recovery:
+ If present, then fault recovery will be enabled.
+
+ - st,ffx-power-output-mode: string
+ The FFX power output mode selects how the FFX output timing is
+ configured. Must be one of these values:
+ - "drop-compensation"
+ - "tapered-compensation"
+ - "full-power-mode"
+ - "variable-drop-compensation" (default)
+
+ - st,drop-compensation-ns: number
+ Only required for "st,ffx-power-output-mode" ==
+ "variable-drop-compensation".
+ Specifies the drop compensation in nanoseconds.
+ The value must be in the range of 0..300, and only
+ multiples of 20 are allowed. Default is 140ns.
+
+ - st,overcurrent-warning-adjustment:
+ If present, overcurrent warning adjustment is enabled.
+
+ - st,max-power-use-mpcc:
+ If present, then MPCC bits are used for MPC coefficients,
+ otherwise standard MPC coefficients are used.
+
+ - st,max-power-corr:
+ If present, power bridge correction for THD reduction near maximum
+ power output is enabled.
+
+ - st,am-reduction-mode:
+ If present, FFX mode runs in AM reduction mode, otherwise normal
+ FFX mode is used.
+
+ - st,odd-pwm-speed-mode:
+ If present, PWM speed mode run on odd speed mode (341.3 kHz) on all
+ channels. If not present, normal PWM spped mode (384 kHz) will be used.
+
+ - st,distortion-compensation:
+ If present, distortion compensation variable uses DCC coefficient.
+ If not present, preset DC coefficient is used.
+
+ - st,invalid-input-detect-mute:
+ If not present, automatic invalid input detect mute is enabled.
+
+
+
+Example:
+
+codec: sta350@38 {
+ compatible = "st,sta350";
+ reg = <0x1c>;
+ reset-gpios = <&gpio1 19 0>;
+ power-down-gpios = <&gpio1 16 0>;
+ st,output-conf = <0x3>; // set output to 2-channel
+ // (full-bridge) power,
+ // 2-channel data-out
+ st,ch1-output-mapping = <0>; // set channel 1 output ch 1
+ st,ch2-output-mapping = <0>; // set channel 2 output ch 1
+ st,ch3-output-mapping = <0>; // set channel 3 output ch 1
+ st,max-power-correction; // enables power bridge
+ // correction for THD reduction
+ // near maximum power output
+ st,invalid-input-detect-mute; // mute if no valid digital
+ // audio signal is provided.
+};

Subject: ASoC: Move IO abstraction to the component level
We currently have two very similar IO abstractions in ASoC, one for CODECs, the
other for platforms. Moving this to the component level will allow us to unify
those two. It will also enable us to move the standard kcontrol helpers as well
as DAPM support to the component level.
The new component level abstraction layer is primarily build around regmap.
There is a per component pointer for the regmap instance for the underlying
device. There are four new function snd_soc_component_read(),
snd_soc_component_write(), snd_soc_component_update_bits() and
snd_soc_component_update_bits_async(). They have the same signature as their
regmap counter-part and will internally forward the call one-to-one to regmap.
If the component it not using regmap it will fallback to using the custom IO
callbacks. This is done to be able to support drivers that haven't been
converted to regmap yet, but it is expected that this will eventually be removed
in the future once all component drivers have been converted to regmap.

From 907fe36a2cd572fe58d98be01457b945c47b996e Mon Sep 17 00:00:00 2001
From: Lars-Peter Clausen
Date: Tue, 22 Apr 2014 13:23:14 +0200
Subject: ASoC: Move standard kcontrol helpers to the component level
After moving the IO layer inside ASoC to the component level we can now easily
move the standard control helpers also to the component level. This allows to
reuse the same standard helper control implementations for other components.
