* | ARM: s3c: Use pwm_get() in favour of pwm_request() in RX1950Uwe Kleine-König2021-04-011-5/+6
|/ | | | | | | | | | | | | | | | | | pwm_request() is deprecated because (among others) it depends on a global numbering of PWM devices. So register a pwm_lookup to pick the right PWM device (identified by provider and its local id) and use pwm_get(). Before this patch the PWM #1 was used. This is provided by the samsung-pwm device which is the only PWM provider on this machine. The local offset is 1, see also commit c107fe904a10 ("ARM: S3C24XX: Use PWM lookup table for mach-rx1950") with a similar conversion for PWM #0. As a follow up specify the period only once and symmetrically use pwm_put() instead of pwm_free() to drop the reference.

* ARM: s3c: Avoid naming clash of S3C24xx and S3C64xx timer setupKrzysztof Kozlowski2020-08-2838-89/+89
| | | | | | | | | | | PWM timer initialization has two independent implementations - one for S3C24xx and one for S3C64xx. The naming however was always the same and before also the declaration was shared. This is confusing, error prone and might cause issues when trying to build multiplatform kernel.
