[PATCH v5 1/5] ASoC: codecs: Add msm8916-wcd analog codec

Srinivas Kandagatla
2016-09-08T13:04:52Z

msm8916-wcd codec is found in Qualcomm msm8916 and apq8016 processors.
This codec IP is split in to two parts (Digital & Analog).
Analog part is integrated in to PMIC PM8916 and the digital part is
integrated into Application processor. Data transfer between Analog and
Digital Die is done via a internal bus called PDM.

This patch adds support to Analog part of the Codec which is integrated
into PMIC PM8916.

+Bindings for codec Analog IP which is integrated in pmic pm8916,
+
+## Bindings for codec core on pmic:
+
+Required properties
+ - compatible = "qcom,msm8916-wcd-analog-codec";
+ - reg: represents the slave base address provided to the peripheral.
+ - interrupt-parent : The parent interrupt controller.
+ - interrupts: List of interrupts in given SPMI peripheral.
+ - interrupt-names: Names specified to above list of interrupts in same
+ order. List of supported interrupt names are:
+ "cdc_spk_cnp_int" - Speaker click and pop interrupt.
+ "cdc_spk_clip_int" - Speaker clip interrupt.
+ "cdc_spk_ocp_int" - Speaker over current protect interrupt.
+ "mbhc_ins_rem_det1" - jack insert removal detect interrupt 1.
+ "mbhc_but_rel_det" - button release interrupt.
+ "mbhc_but_press_det" - button press event
+ "mbhc_ins_rem_det" - jack insert removal detect interrupt.
+ "mbhc_switch_int" - multi button headset interrupt.
+ "cdc_ear_ocp_int" - Earphone over current protect interrupt.
+ "cdc_hphr_ocp_int" - Headphone R over current protect interrupt.
+ "cdc_hphl_ocp_det" - Headphone L over current protect interrupt.
+ "cdc_ear_cnp_int" - earphone cnp interrupt.
+ "cdc_hphr_cnp_int" - hphr click and pop interrupt.
+ "cdc_hphl_cnp_int" - hphl click and pop interrupt.
+
+ - clocks: Handle to mclk.
+ - clock-names: should be "mclk".
+ - VDD-CDC-IO-supply: phandle to VDD_CDC_IO regulator device tree node.
+ - VDD-CDC-TX-RX-CX-supply: phandle to VDD_CDC_TX/RX/CX regulator device tree node.
+ - VDD-MICBIAS-supply: phandle of VDD_MICBIAS supply's regulator device tree node.
+
+Optional Properties:
+- qcom,micbias1-ext-cap: present if micbias1 has external capacitor connected.
+- qcom,micbias2-ext-cap: present if micbias2 has external capacitor connected.
