Subject: [v2 0/2] Support pwm driver for aspeed ast26xx
Date: Wed, 14 Apr 2021 18:49:37 +0800 [thread overview]
Message-ID: <20210414104939.1093-1-billy_tsai@aspeedtech.com> (raw)
The legacy driver of aspeed pwm is binding with tach controller and it
doesn't follow the pwm framworks usage. In addition, the pwm register
usage of the 6th generation of ast26xx has drastic change. So these
patch serials add the new aspeed pwm driver to fix up the problem above.
Changes since v1:
- Fix the dt_binding_check fail suggested by Rob Herring
- Add depends to PWM_ASPEED_G6 configure suggested by Uwe Kleine-Konig
- pwm-aspeed-g6.c suggested by Uwe Kleine-König
- Fix license header
- Use bitfiled.h macro to define register fields
- Implement .remove device function
- Implement .get_state pwm api
