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.

-------
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.
