 MediaTek display PWM controller
 
 Required properties:
- - compatible: should be "mediatek,<name>-disp-pwm":
-   - "mediatek,mt8173-disp-pwm": found on mt8173 SoC.
+ - compatible: should be like these:
+   - "mediatek,mt2701-disp-bls": found on mt2701 SoC.

Why bls instead of pwm?

In mt6595/mt8173, we have a hardware module named pwm.
In mt2701, we have bls hardware module which includes disp pwm function,
so we named it mt2701-disp-bls rather than mt2701-disp-pwm in order to
match with hardware spec.
thanks.
