Subject: [PATCH v3 0/4] leds: leds-pwm: Device tree support
Date: Mon, 10 Dec 2012 11:00:33 +0100 [thread overview]
Message-ID: <1355133637-2784-1-git-send-email-peter.ujfalusi@ti.com> (raw)
Hello,
Changes since v2:
- rebased on top of linux-next
- DT bindings now alligned with Grant's request
- exporting of_pwm_request() from PWM core to allow clean DT bindings
- DT binding documentation changed to reflect the changes
Changes since v1:
- As suggested by Bryan Wu: the legacy pwm_request() has been removed from
patch 1
- Device tree bindings added for leds-pwm driver.
When we boot with Device tree we handle one LED per device to be more aligned
with PWM core's DT implementation.
An example of the DT usage is provided in the new DT binding documentation for
leds-pwm.
Tested on OMAP4 Blaze (SDP) with legacy and DT boot.
Regards,
Peter
