CS35L33 Speaker Amplifier
Required properties:
- compatible : "cirrus,cs35l33"
- 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.
Optional properties:
- reset-gpios : gpio used to reset the amplifier
- interrupt-parent : Specifies the phandle of the interrupt controller to
which the IRQs from CS35L33 are delivered to.
- interrupts : IRQ line info CS35L33.
(See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
for further information relating to interrupt properties)
- cirrus,boost-ctl : Booster voltage use to supply the amp. If the value is
0, then VBST = VP. If greater than 0, the boost voltage will be 3300mV with
a value of 1 and will increase at a step size of 100mV until a maximum of
8000mV.
- cirrus,ramp-rate : On power up, it affects the time from when the power
up sequence begins to the time the audio reaches a full-scale output.
On power down, it affects the time from when the power-down sequence
begins to when the amplifier disables the PWM outputs. If this property
is not set then soft ramping will be disabled and ramp time would be
20ms. If this property is set to 0,1,2,3 then ramp times would be 40ms,
60ms,100ms,175ms respectively for 48KHz sample rate.
- cirrus,boost-ipk : The maximum current allowed for the boost converter.
The range starts at 1850000uA and goes to a maximum of 3600000uA
with a step size of 15625uA. The default is 2500000uA.
- cirrus,imon-adc-scale : Configures the scaling of data bits from the IMON
ADC data word. This property can be set as a value of 0 for bits 15 down
to 0, 6 for 21 down to 6, 7, for 22 down to 7, 8 for 23 down to 8.
Optional H/G Algorithm sub-node:
The cs35l33 node can have a single "cirrus,hg-algo" sub-node that will enable
the internal H/G Algorithm.
- cirrus,hg-algo : Sub-node for internal Class H/G algorithm that
controls the amplifier supplies.
Optional properties for the "cirrus,hg-algo" sub-node:
- cirrus,mem-depth : Memory depth for the Class H/G algorithm measured in
LRCLK cycles. If this property is set to 0, 1, 2, or 3 then the memory
depths will be 1, 4, 8, 16 LRCLK cycles. The default is 16 LRCLK cycles.
cirrus,release-rate : The number of consecutive LRCLK periods before
allowing release condition tracking updates. The number of LRCLK periods
start at 3 to a maximum of 255.
- cirrus,ldo-thld : Configures the signal threshold at which the PWM output
stage enters LDO operation. Starts as a default value of 50mV for a value
of 1 and increases with a step size of 50mV to a maximum of 750mV (value of
0xF).
- cirrus,ldo-path-disable : This is a boolean property. If present, the H/G
algorithm uses the max detection path. If not present, the LDO
detection path is used.
- cirrus,ldo-entry-delay : The LDO entry delay in milliseconds before the H/G
algorithm switches to the LDO voltage. This property can be set to values
from 0 to 7 for delays of 5ms, 10ms, 50ms, 100ms, 200ms, 500ms, 1000ms.
The default is 100ms.
- cirrus,vp-hg-auto : This is a boolean property. When set, class H/G VPhg
automatic updating is enabled.
- cirrus,vp-hg : Class H/G algorithm VPhg. Controls the H/G algorithm's
reference to the VP voltage for when to start generating a boosted VBST.
The reference voltage starts at 3000mV with a value of 0x3 and is increased
by 100mV per step to a maximum of 5500mV.
- cirrus,vp-hg-rate : The rate (number of LRCLK periods) at which the VPhg is
allowed to increase to a higher voltage when using VPhg automatic
tracking. This property can be set to values from 0 to 3 with rates of 128
periods, 2048 periods, 32768 periods, and 524288 periods.
The default is 32768 periods.
- cirrus,vp-hg-va : VA calculation reference for automatic VPhg tracking
using VPMON. This property can be set to values from 0 to 6 starting at
1800mV with a step size of 50mV up to a maximum value of 1750mV.
Default is 1800mV.
Example:
cs35l33: cs35l33@40 {
compatible = "cirrus,cs35l33";
reg = <0x40>;
VA-supply = <&ldo5_reg>;
VP-supply = <&ldo5_reg>;
interrupt-parent = <&gpio8>;
interrupts = <3 IRQ_TYPE_LEVEL_LOW>;
reset-gpios = <&cs47l91 34 0>;
cirrus,ramp-rate = <0x0>;
cirrus,boost-ctl = <0x30>; /* VBST = 8000mV */
cirrus,boost-ipk = <0xE0>; /* 3600mA */
cirrus,imon-adc-scale = <0> /* Bits 15 down to 0 */
cirrus,hg-algo {
