'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.

CS35L34 Speaker Amplifier
|
|
|
|
Required properties:
|
|
|
|
- compatible : "cirrus,cs35l34"
|
|
|
|
- reg : the I2C address of the device for I2C.
|
|
|
|
- VA-supply, VP-supply : power supplies for the device,
|
|
as covered in
|
|
Documentation/devicetree/bindings/regulator/regulator.txt.
|
|
|
|
- cirrus,boost-vtge-millivolt : Boost Voltage Value. Configures the boost
|
|
converter's output voltage in mV. The range is from VP to 8V with
|
|
increments of 100mV.
|
|
|
|
- cirrus,boost-nanohenry: Inductor value for boost converter. The value is
|
|
in nH and they can be values of 1000nH, 1100nH, 1200nH, 1500nH, and 2200nH.
|
|
|
|
Optional properties:
|
|
|
|
- reset-gpios: GPIO used to reset the amplifier.
|
|
|
|
- interrupts : IRQ line info CS35L34.
|
|
(See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
|
|
for further information relating to interrupt properties)
|
|
|
|
- cirrus,boost-peak-milliamp : Boost converter peak current limit in mA. The
|
|
range starts at 1200mA and goes to a maximum of 3840mA with increments of
|
|
80mA. The default value is 2480mA.
|
|
|
|
- cirrus,i2s-sdinloc : ADSP SDIN I2S channel location. Indicates whether the
|
|
received mono data is in the left or right portion of the I2S frame
|
|
according to the AD0 pin or directly via this configuration.
|
|
0x0 (Default) = Selected by AD0 input (if AD0 = LOW, use left channel),
|
|
0x2 = Left,
|
|
0x1 = Selected by the inversion of the AD0 input (if AD0 = LOW, use right
|
|
channel),
|
|
0x3 = Right.
|
|
|
|
- cirrus,gain-zc-disable: Boolean property. If set, the gain change will take
|
|
effect without waiting for a zero cross.
|
|
|
|
- cirrus,tdm-rising-edge: Boolean property. If set, data is on the rising edge of
|
|
SCLK. Otherwise, data is on the falling edge of SCLK.
|
|
|
|
|
|
Example:
|
|
|
|
cs35l34: cs35l34@40 {
|
|
compatible = "cirrus,cs35l34";
|
|
reg = <0x40>;
|
|
|
|
interrupt-parent = <&gpio8>;
|
|
interrupts = <3 IRQ_TYPE_LEVEL_LOW>;
|
|
|
|
reset-gpios = <&gpio 10 0>;
|
|
|
|
cirrus,boost-vtge-milltvolt = <8000>; /* 8V */
|
|
cirrus,boost-ind-nanohenry = <1000>; /* 1uH */
|
|
cirrus,boost-peak-milliamp = <3000>; /* 3A */
|
|
};
