pwm: rk_pwm: Make PWM driver to support all Rockchip Socs

2019-12-05T16:06:23Z

This PWM driver can be used to support pwm functions for on all Rockchip Socs. The previous chips than RK3288 did not support polarity, and register layout was different from the RK3288 PWM. The RK3288 keep the current functions. RK3328 and the chips after it, which can support hardware lock, configure duty, period and polarity at next same period, to prevent the intermediate temporary state.

rockchip: use 'arch-rockchip' as header file path

2019-04-30T22:00:05Z

Rockchip use 'arch-rockchip' instead of arch-$(SOC) as common header file path, so that we can get the correct path directly. Signed-off-by: Kever Yang Reviewed-by: Philipp Tomsich

pwm: sunxi: choose best prescaler to improve PWM resolution

2018-10-24T16:27:16Z

Choose best prescaler to improve PWM resolution. Without this change driver chooses first prescaler that gives us period value within range, but it could be not the best one. Signed-off-by: Vasily Khoruzhick Tested-by: Vagrant Cascadian Acked-by: Maxime Ripard Reviewed-by: Jagan Teki

pwm: sunxi: use new prescaler when configuring PWM

Looks like old prescaler was used when configuring PWM, fix it. Signed-off-by: Vasily Khoruzhick Acked-by: Maxime Ripard Reviewed-by: Jagan Teki

pwm: sunxi: fix off-by-one that prevented PWM to use prescaler bypass

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini
