From: Ernest Van Hoecke <ernest.vanhoecke@xxxxxxxxxxx> Add two properties to select the IN1L/DMICDAT1 and IN2R/DMICDAT2 functionality: - wlf,in1l-as-dmicdat1 - wlf,in1r-as-dmicdat2 Add a property to describe the GPIO configuration registers, that can be used to set the four multifunction pins: - wlf,gpio-cfg Add a property to describe the mic bias control registers: - wlf,mic-cfg Add two properties to describe the Dynamic Range Controller (DRC), allowing multiple named configurations where each config sets the 4 DRC registers (R40-R43): - wlf,drc-cfg-regs - wlf,drc-cfg-names Add three properties to describe the equalizer (ReTune Mobile), allowing multiple named configurations (associated with a samplerate) that set the 24 (R134-R157) EQ registers: - wlf,retune-mobile-cfg-regs - wlf,retune-mobile-cfg-names - wlf,retune-mobile-cfg-rates Datasheet: https://statics.cirrus.com/pubs/proDatasheet/WM8904_Rev4.1.pdf Signed-off-by: Ernest Van Hoecke <ernest.vanhoecke@xxxxxxxxxxx> Signed-off-by: Francesco Dolcini <francesco.dolcini@xxxxxxxxxxx> --- .../devicetree/bindings/sound/wlf,wm8904.yaml | 88 +++++++++++++++++++ 1 file changed, 88 insertions(+) diff --git a/Documentation/devicetree/bindings/sound/wlf,wm8904.yaml b/Documentation/devicetree/bindings/sound/wlf,wm8904.yaml index 329260cf0fa0..b89d9db02848 100644 --- a/Documentation/devicetree/bindings/sound/wlf,wm8904.yaml +++ b/Documentation/devicetree/bindings/sound/wlf,wm8904.yaml @@ -38,6 +38,74 @@ properties: DCVDD-supply: true MICVDD-supply: true + wlf,in1l-as-dmicdat1: + type: boolean + description: + Use IN1L/DMICDAT1 as DMICDAT1, enabling the DMIC input path. + + wlf,in1r-as-dmicdat2: + type: boolean + description: + Use IN1R/DMICDAT2 as DMICDAT2, enabling the DMIC input path. + + wlf,gpio-cfg: + $ref: /schemas/types.yaml#/definitions/uint32-array + minItems: 4 + maxItems: 4 + description: + Default register values for R121/122/123/124 (GPIO Control). + If any entry has the value 0xFFFF, the related register won't be set. + default: [0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF] + + wlf,mic-cfg: + $ref: /schemas/types.yaml#/definitions/uint32-array + minItems: 2 + maxItems: 2 + description: + Default register values for R6/R7 (Mic Bias Control). + default: [0, 0] + + wlf,drc-cfg-names: + $ref: /schemas/types.yaml#/definitions/string-array + description: + List of strings for the available DRC modes. + If absent, DRC is disabled. + + wlf,drc-cfg-regs: + $ref: /schemas/types.yaml#/definitions/uint16-array + description: + Default register values for R40/41/42/43 (DRC). + The list must be 4 times the length of wlf,drc-cfg-names. + If absent, DRC is disabled. + + wlf,retune-mobile-cfg-names: + $ref: /schemas/types.yaml#/definitions/string-array + description: + List of strings for the available retune modes. + If absent, retune is disabled. + + wlf,retune-mobile-cfg-rates: + $ref: /schemas/types.yaml#/definitions/uint32-array + description: + List of rates for the available retune modes. + The list must be the same length as wlf,retune-mobile-cfg-names. + If absent, retune is disabled. + + wlf,retune-mobile-cfg-regs: + $ref: /schemas/types.yaml#/definitions/uint16-array + description: + Default register values for R134/.../157 (EQ). + The list must be 24 times the length of wlf,retune-mobile-cfg-names. + If absent, retune is disabled. + +dependencies: + wlf,drc-cfg-names: [ 'wlf,drc-cfg-regs' ] + wlf,drc-cfg-regs: [ 'wlf,drc-cfg-names' ] + + wlf,retune-mobile-cfg-names: [ 'wlf,retune-mobile-cfg-rates', 'wlf,retune-mobile-cfg-regs' ] + wlf,retune-mobile-cfg-regs: [ 'wlf,retune-mobile-cfg-names', 'wlf,retune-mobile-cfg-rates' ] + wlf,retune-mobile-cfg-rates: [ 'wlf,retune-mobile-cfg-names', 'wlf,retune-mobile-cfg-regs' ] + required: - compatible - reg @@ -70,5 +138,25 @@ examples: DBVDD-supply = <®_1p8v>; DCVDD-supply = <®_1p8v>; MICVDD-supply = <®_1p8v>; + + wlf,drc-cfg-names = "default", "peaklimiter", "tradition", "soft", "music"; + wlf,drc-cfg-regs = + /* coded default: KNEE_IP = KNEE_OP = 0, HI_COMP = LO_COMP = 1 */ + /bits/ 16 <0x01af 0x3248 0x0000 0x0000>, + /* coded default: KNEE_IP = -24, KNEE_OP = -6, HI_COMP = 1/4, LO_COMP = 1 */ + /bits/ 16 <0x04af 0x324b 0x0010 0x0408>, + /* coded default: KNEE_IP = -42, KNEE_OP = -3, HI_COMP = 0, LO_COMP = 1 */ + /bits/ 16 <0x04af 0x324b 0x0028 0x0704>, + /* coded default: KNEE_IP = -45, KNEE_OP = -9, HI_COMP = 1/8, LO_COMP = 1 */ + /bits/ 16 <0x04af 0x324b 0x0018 0x078c>, + /* coded default: KNEE_IP = -30, KNEE_OP = -10.5, HI_COMP = 1/4, LO_COMP = 1 */ + /bits/ 16 <0x04af 0x324b 0x0010 0x050e>; + + wlf,gpio-cfg = < + 0x0018 /* GPIO1 => DMIC_CLK */ + 0xffff /* GPIO2 => don't touch */ + 0xffff /* GPIO3 => don't touch */ + 0xffff /* GPIO4 => don't touch */ + >; }; }; -- 2.39.5
