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 Billy Tsai (2): dt-bindings: Add bindings for aspeed pwm-tach and pwm. pwm: Add Aspeed ast2600 PWM support .../bindings/mfd/aspeed,ast2600-pwm-tach.yaml | 60 ++++ .../bindings/pwm/aspeed,ast2600-pwm.yaml | 44 +++ drivers/pwm/Kconfig | 7 + drivers/pwm/Makefile | 1 + drivers/pwm/pwm-aspeed-g6.c | 324 ++++++++++++++++++ 5 files changed, 436 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/aspeed,ast2600-pwm-tach.yaml create mode 100644 Documentation/devicetree/bindings/pwm/aspeed,ast2600-pwm.yaml create mode 100644 drivers/pwm/pwm-aspeed-g6.c -- 2.25.1 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
