2017-01-04pwm: Remove .can_sleep from struct pwm_chipThierry Reding1-1/+0
All PWM devices have been marked as "might sleep" since v4.5, there is no longer a need to differentiate on a per-chip basis. Signed-off-by: Thierry Reding <[email protected]>
2016-03-23pwm: brcmstb: Fix check of devm_ioremap_resource() return codeVladimir Zapolskiy1-2/+2
The change fixes potential oops while accessing iomem on invalid address if devm_ioremap_resource() fails due to some reason. The devm_ioremap_resource() function returns ERR_PTR() and never returns NULL, which makes useless a following check for NULL.

2015-10-06pwm: Add Broadcom BCM7038 PWM controller supportFlorian Fainelli1-0/+343
Add support for the BCM7038-style PWM controller found in all BCM7xxx STB SoCs. This controller has a hardcoded 2 channels per controller, and cascades a variable frequency generator on top of a fixed frequency generator which offers a range of a 148ns period all the way to ~622ms periods.
