The patches are mostly based on Wesley's patch. v4 - Rename the property sifive,approx-period-ns to sifive,period-ns - Rename macros with appropriate names - Remove unused macros - Rename struct sifive_pwm_device to struct pwm_sifive_ddata - Rename function prefix as per driver name - Set deglitch bit before changing output waveform. - Other minor fixes based upon feedback on v3 v3 - Add a link to the reference manaul - Use appropriate apis for division operation - Add check for polarity - Enable clk before calling clk_get_rate - Other minor fixes based upon feedback on v2 V2 changed from V1: - Remove inclusion of dt-bindings/pwm/pwm.h - Remove artificial alignments - Replace ioread32/iowrite32 with readl/writel - Remove camelcase - Change dev_info to dev_dbg for unnecessary log - Correct typo in driver name - Remove use of of_match_ptr macro - Update the DT compatible strings and Add reference to a common versioning document Yash Shah (2): pwm: sifive: Add DT documentation for SiFive PWM Controller pwm: sifive: Add a driver for SiFive SoC PWM .../devicetree/bindings/pwm/pwm-sifive.txt | 37 +++ drivers/pwm/Kconfig | 11 + drivers/pwm/Makefile | 1 + drivers/pwm/pwm-sifive.c | 262 +++++++++++++++++++++ 4 files changed, 311 insertions(+) create mode 100644 Documentation/devicetree/bindings/pwm/pwm-sifive.txt create mode 100644 drivers/pwm/pwm-sifive.c -- 1.9.1
