Subject: [PATCH v3 0/2] pwm: add support for NXPs high-side switch MC33XS2410
Date: Wed, 15 May 2024 13:20:32 +0200 [thread overview]
Message-ID: <20240515112034.298116-1-dima.fedrau@gmail.com> (raw)
The MC33XS2410 is a four channel high-side switch. Featuring advanced
monitoring and control function, the device is operational from 3.0 V to
60 V. The device is controlled by SPI port for configuration.
Changes in V2:
- fix title in devicetree binding
- fix commit message in devicetree binding patch
- remove external clock from pwms and create clocks property
- switch to unevaluatedProperties: false
- add missing properties for complete example:
- pwm-names
- pwms
- interrupts
- clocks
Changes in V3:
- Add description of the general behaviour of the device (limitations)
- Drop unused defines
- Add ranges comments for defines with parameters
- Drop MC33XS2410_PERIOD_MAX, MC33XS2410_PERIOD_MIN defines
- Drop mc33xs2410_period variable
- Round down when calculating period and duty cycle
- Use switch instead of loop when calculating frequency
- Removed ret variable in mc33xs2410_pwm_get_freq
- Handle all accesses in a single call to spi_sync_transfer
- Fix comments in function mc33xs2410_pwm_get_period
- Fix call pwm_set_relative_duty_cycle(state, ret, 255), instead
pwm_set_relative_duty_cycle(state, val[1] + 1, 256);
- Use devm_pwmchip_alloc
- Fix typo s/Transitition/Transition/
- Drop driver_data
- Removed patch for direct inputs from series
- Tested with PWM_DEBUG enabled, didn't before !
