pwm: atmel: Remove useless symbolic definitions

2019-03-04T11:52:49+00:00

The values that these symbols define are only assigned to the per-SoC structure where the context is clear, so there's no need for the extra symbolic name. Acked-by: Claudiu Beznea Signed-off-by: Thierry Reding

pwm: bcm-kona: Update macros to remove braces around numbers

2019-03-04T11:52:49+00:00

Parentheses are not needed around integer literals in macros. Remove them. Signed-off-by: Sheetal Tigadoli Acked-by: Uwe Kleine-König Signed-off-by: Thierry Reding

pwm: imx27: Only enable the clocks once in .get_state()

2019-03-04T11:52:48+00:00

Currently the function pwm_imx27_get_state() of enables the clocks once unconditionally at the start, a second time if the PWM is enabled and disables unconditionally at the end. Simplify that to enable once at the start and disable conditionally at the end. Signed-off-by: Uwe Kleine-König Signed-off-by: Thierry Reding

pwm: rcar: Improve calculation of divider

2019-03-04T11:14:21+00:00

The rcar_pwm_get_clock_division() has a loop to calculate the divider, but the value of div should be calculatable without a loop. So, this patch improves it. This algorithm is suggested by Uwe Kleine-König and Laurent Pinchart. Signed-off-by: Yoshihiro Shimoda Acked-by: Uwe Kleine-König Signed-off-by: Thierry Reding

pwm: rcar: Remove legacy APIs

2019-03-04T11:14:07+00:00

This patch removes legacy APIs. Since rcar_pwm_{en,dis}able() functions are reused on "atomic" API, this patch changes the arguments of these functions. No change in behavior. Signed-off-by: Yoshihiro Shimoda Acked-by: Uwe Kleine-König Signed-off-by: Thierry Reding

pwm: rcar: Use "atomic" API on rcar_pwm_resume()

2019-03-04T11:14:06+00:00

To remove legacy API related functions in the future, this patch uses "atomic" related function instead. No change in behavior. Signed-off-by: Yoshihiro Shimoda Acked-by: Uwe Kleine-König Signed-off-by: Thierry Reding

pwm: rcar: Add support "atomic" API

2019-03-04T11:14:05+00:00

This patch adds support for "atomic" API. This behavior differs with legacy APIs a little. Legacy APIs: The PWMCNT register will be updated in rcar_pwm_config() even if the PWM state is disabled. Atomic API: The PWMCNT register will be updated in rcar_pwm_apply() only if the PWM state is enabled. Otherwize, if a PWM runs with 30% duty cycles and the pwm_apply_state() is called with state->enabled = 0, ->duty_cycle = 60 and ->period = 100, this is possible to output a 60% duty cycle.

pwm: atmel: Add support for SAM9X60's PWM controller

2019-03-04T10:57:44+00:00

Add support for SAM9X60's PWM controller. Signed-off-by: Claudiu Beznea Signed-off-by: Thierry Reding

pwm: atmel: Rename objects of type atmel_pwm_data

2019-03-04T10:56:48+00:00

Rename objects of type atmel_pwm_data to contain chip name instead of version number. Signed-off-by: Claudiu Beznea Signed-off-by: Thierry Reding

pwm: atmel: Add support for controllers with 32 bit counters

2019-03-04T10:56:08+00:00

SAM9X60's PWM controller uses 32 bits counters thus it could generate signals with higher period and duty cycles than the old ones. Prepare the current driver to be able to work with old controllers (that uses 16 bits counters) and with the new SAM9X60's controller, by providing counters information based on compatible string.
