2022-12-06pwm: Make .get_state() callback return an error codeUwe Kleine-König
.get_state() might fail in some cases. To make it possible that a driver signals such a failure change the prototype of .get_state() to return an error code. This patch was created using coccinelle and the following semantic patch: @p1@ identifier getstatefunc; identifier driver; @@ struct pwm_ops driver = { ..., .get_state = getstatefunc ,... }; @p2@ identifier p1.getstatefunc; identifier chip, pwm, state; @@ -void +int getstatefunc(struct pwm_chip *chip, struct pwm_device *pwm, struct pwm_state *state) { ... - return; + return 0; ... } plus the actual change of the prototype in include/linux/pwm.h (plus some manual fixing of indentions and empty lines). So for now all drivers return success unconditionally. They are adapted in the following patches to make the changes easier reviewable.

2022-12-06pwm: pxa: Set duty cycle to 0 when disabling PWMDoug Brown
When disabling PWM, the duty cycle needs to be set to 0. This prevents the previous duty cycle from showing up momentarily when the clock is re-enabled next time. Because the clock has to be running in order to configure the duty cycle, unconditionally enable it early in pxa_pwm_apply and account for the correct enable count at the end.

According to MT7622 Reference Manual for Development Board v1.0 the PWM unit found in the MT7622 SoC also comes with the PWM_CK_26M_SEL register at offset 0x210 just like other modern MediaTek ARM64 SoCs. And also MT7622 sets that register to 0x00000001 on reset which is described as 'Select 26M fix CLK as BCLK' in the datasheet. Hence set has_ck_26m_sel to true also for MT7622 which results in the driver writing 0 to the PWM_CK_26M_SEL register which is described as 'Select bus CLK as BCLK'.
