Phytium PWM controller
|
|
|
|
Required properties:
|
|
- compatible: should be "phytium,pwm"
|
|
- reg: physical base address and length of the controller's registers
|
|
- interrupts: interrupt for the pwm controller
|
|
- clocks : clock specifiers for both ipg and per clocks.
|
|
- phytium,db: One or two <cntmod dutymod div updbcly dbpolarity> to describe dead-band configurations.
|
|
"cntmod" indicates the counter mode (0 for modulo, 1 for up-and-down).
|
|
"dutymod" indicdates which duty to compare with (0 for PMW_CCR, 1 for FIFO).
|
|
"div" selects the clock divider value, from 0 to 1023.
|
|
"updbcly" selects the rising edge delay cycles.
|
|
"dbpolarity" selects the polarity for dead-band.
|
|
|
|
Example:
|
|
|
|
pwm0: pwm@2804a000 {
|
|
compatible = "phytium,pwm";
|
|
reg= <0x0 0x2804a000 0x0 0x1000>;
|
|
interrupts = <GIC_SPI 173 IRQ_TYPE_LEVEL_HIGH>;
|
|
clocks = <&sysclk_48mhz>;
|
|
phytium,db = <0 0 0 1000 0>;
|
|
};
