Hi all:

This patchset introduce a generic PWM framework driver for Loongson family.
Each PWM has one pulse width output signal and one pulse input signal to be measured.

It can be found on Loongson-2K series cpus and Loongson LS7A bridge chips.

Thanks.

-------
V3:
patch (1/2):
 - Add Reviewed-by tag from Krzysztof, thanks.
patch (2/2):
 - Several code stlye adjustments, such as line breaks.

Link to V2:
https://lore.kernel.org/all/cover.1712732719.git.zhoubinbin@loongson.cn/

v2:
- Remove the dts-related patches and update dts at once after all
relevant drivers are complete.
patch (1/2):
 - The dt-binding filename should match compatible, rename it as
   loongson,ls7a-pwm.yaml;
 - Update binding description;
 - Add description for each pwm cell;
 - Drop '#pwm-cells' from required, for pwm.yaml makes it required already.

Link to v1:
https://lore.kernel.org/linux-pwm/cover.1711953223.git.zhoubinbin@loongson.cn/

  dt-bindings: pwm: Add Loongson PWM controller
  pwm: Add Loongson PWM controller support

Hi Uwe:

Gentle ping.
The dt-binding part of the patchset looks good now, do you have any
comments on the driver part?

Thanks.
