Merge tag 'asoc-v3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: Updates for v3.16 Lots of cleanup work going on in the core this release but very little visible to external users except for the new drivers that have been added. - Support for specifying aux CODECs in DT. - Removal of the deprecated mux and enum macros. - More moves towards full componentisation. - Removal of some unused I/O code. - Lots of cleanups, fixes and enhancements to the davinci, Freescale, Haswell and Realtek drivers. - Several drivers exposed directly in Kconfig for use with simple-card. - New drivers for Cirrus CS42L56, Realtek RT5639, RT5642 and RT5651 and ST STA350.

+- dai-tdm-slot-num : Please refer to tdm-slot.txt.
+- dai-tdm-slot-width : Please refer to tdm-slot.txt.
- clocks / system-clock-frequency : specify subnode's clock if needed.
it can be specified via "clocks" if system has
clock node (= common clock), or "system-clock-frequency"
(if system doens't support common clock)
-Note:
- * For 'format', 'frame-master', 'bitclock-master', 'bitclock-inversion' and
- 'frame-inversion', the simple card will use the settings of CODEC for both
- CPU and CODEC sides as we need to keep the settings identical for both ends
- of the link.

+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.
+ This property has to be specified as '/bits/ 8' value.
+
+ - 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.
+ This properties have to be specified as '/bits/ 8' values.
+
+ - 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 present, automatic invalid input detect mute is enabled.
+
+ - st,activate-mute-output:

+ reach a value lower than -76 dBFS.
+
+ - st,bridge-immediate-off:
+ If present, the bridge will be switched off immediately after the
+ power-down-gpio goes low. Otherwise, the bridge will wait for 13
+ million clock cycles to pass before shutting down.
+
+ - st,noise-shape-dc-cut:
+ If present, the noise-shaping technique on the DC cutoff filter are
+ enabled.
+
+ - st,powerdown-master-volume:
+ If present, the power-down pin and I2C power-down functions will
+ act on the master volume. Otherwise, the functions will act on the
+ mute commands.
+
+ - st,powerdown-delay-divider:
+ If present, the bridge power-down time will be divided by the provided
+ value. If not specified, a divider of 1 will be used. Allowed values
+ are 1, 2, 4, 8, 16, 32, 64 and 128.
+ This property has to be specified as '/bits/ 8' value.

+ // (full-bridge) power,
+ // 2-channel data-out
+ st,ch1-output-mapping = /bits/ 8 <0>; // set channel 1 output ch 1
+ st,ch2-output-mapping = /bits/ 8 <0>; // set channel 2 output ch 1
