Subject: [PATCH v5 0/2] PWM support for HiFive Unleashed
Date: Tue, 29 Jan 2019 17:13:17 +0530	[thread overview]
Message-ID: <1548762199-7065-1-git-send-email-yash.shah@sifive.com> (raw)

This patch series adds a PWM driver and DT documentation
for HiFive Unleashed board. The patches are mostly based on
Wesley's patch.

v5
- Correct the order of compatible string properties
- PWM state correction to be done always
- Other minor fixes based upon feedback on v4

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
