2013-10-08pwm: mxs: Remove redundant of_match_ptrGravatar Sachin Kamat 1-1/+1
The data structure of_match_ptr() protects is always compiled in. Hence of_match_ptr() is not needed. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Acked-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
2013-09-03pwm: mxs: Check the return value from stmp_reset_block()Gravatar Fabio Estevam 1-1/+7
stmp_reset_block() may fail, so let's check its return value and propagate it in the case of error. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
2013-06-12pwm: Fill in missing .owner fieldsGravatar Thierry Reding 1-0/+1
Some drivers don't set the .owner fields of the struct device_driver or struct pwm_ops, which causes the module usage count to become wrong. Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
2013-05-27pwm: mxs: Let device core handle pinctrlGravatar Fabio Estevam 1-6/+0
Since commit ab78029 (drivers/pinctrl: grab default handles from device core), we can rely on device core for handling pinctrl. So remove devm_pinctrl_get_select_default() from the driver.

2013-04-23pwm: Constify OF match tablesGravatar Thierry Reding 1-1/+1
A few drivers already annotate this properly. Make the same change for all other OF supporting drivers.

2013-01-22pwm: Convert to devm_ioremap_resource()Gravatar Thierry Reding 1-3/+3
Convert all uses of devm_request_and_ioremap() to the newly introduced devm_ioremap_resource() which provides more consistent error handling.

2012-11-28pwm: remove use of __devexitGravatar Bill Pemberton 1-1/+1
CONFIG_HOTPLUG is going away as an option so __devexit is no longer needed. Signed-off-by: Bill Pemberton <wfp5p@virginia.edu> Acked-by: Thierry Reding <thierry.reding@avionic-design.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-07-23pwm: pwm-mxs: use global reset function stmp_reset_blockGravatar Shawn Guo 1-2/+2
Use global reset function stmp_reset_block instead of mxs_reset_block to remove <mach/common.h> inclusion. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2012-07-23pwm: pwm-mxs: encode soc name in compatible stringGravatar Shawn Guo 1-1/+1
Encode soc name in the compatible string to know the specific version hardware block. This is the general approach adopted for most bindings. Change mxs-pwm binding to use the approach. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
