*	drivers/pwm: don't check resource with devm_ioremap_resource	Wolfram Sang	2013-05-18	1	-5/+0
\| \| \| \| \| \| \| \|	devm_ioremap_resource does sanity checks on the given resource. No need to duplicate this in the driver. Signed-off-by: Wolfram Sang <wsa@the-dreams.de> Acked-by: Stephen Warren <swarren@nvidia.com>
*	pwm: pwm-tipwmss: add CONFIG_PM_SLEEP to suspend/resume functions	Jingoo Han	2013-03-11	1	-0/+2
\| \| \| \| \| \| \| \| \| \| \|	This patch adds CONFIG_PM_SLEEP to suspend/resume functions to fix the following build warning when CONFIG_PM_SLEEP is not selected. drivers/pwm/pwm-tipwmss.c:104:12: warning: 'pwmss_suspend' defined but not used [-Wunused-function] drivers/pwm/pwm-tipwmss.c:113:12: warning: 'pwmss_resume' defined but not used [-Wunused-function] Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
*	pwm: Convert to devm_ioremap_resource()	Thierry Reding	2013-01-22	1	-3/+3
\| \| \| \| \| \| \| \| \|	Convert all uses of devm_request_and_ioremap() to the newly introduced devm_ioremap_resource() which provides more consistent error handling.

*	pwm: Add TI PWM subsystem driver	Philip, Avinash	2012-11-28	1	-0/+139
	In some platforms (like am33xx), PWM sub modules (ECAP, EHRPWM, EQEP) are integrated to PWM subsystem. These PWM submodules has resources shared and only one register bit-field is provided to control module/clock enable/disable, makes it difficult to handle common resources from independent PWMSS submodule drivers. So the solution here implemented in this patch is, to create driver for PWMSS and take the role of parent driver for PWM submodules. PWMSS parent driver enumerates all the child nodes under PWMSS module. Also symbol "pwmss_submodule_state_change" exported to enable clock gating for individual PWMSS submodules, and submodule drivers has to enable clock gating from their drivers. As this is only supported during DT boot, the parent/child relationship is created and populated in DT execution flow. The only required change is inside DTS file, making EHRPWM & ECAP as a child to PWMSS node.
