Subject: i.MX pwm patches
Date: Tue, 28 Aug 2012 13:48:15 +0200 [thread overview]
Message-ID: <1346154504-5623-1-git-send-email-s.hauer@pengutronix.de> (raw)
Hi All,
The following patches are an overdue work on the i.MX pwm driver.
- introduce SoC specific functions to make the driver easier to maintain
- use peripheral clock for pwm output unconditionally
- separate the two clocks this module has
- enable ipg clock for register accesses, peripheral clock for enabling
the pwm
- make the driver safe for calling pwm_config before pwm_enable
- Add devicetree support for i.MX53
The platform device support is still implemented using cpu_is_*, I think
this can be dropped completely soon as this driver has no in kernel users
currently, so there should be no need to keep compatibility for platform
based boards.
Hopefully this series fixes the issues mentioned by Benoît. It has been
tested on an i.MX53 only.
Sascha
