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.
From what I understand pwm module and disp pwm in mt6589/mt8173 is
independent from the disp pwm. Actually the disp pwm in mt6589 is part
of the bls module, so this should me mediatek,mt2701-disp-pwm as well
Thanks,
Matthias

- reg: physical base address and length of the controller's registers.
- #pwm-cells: must be 2. See pwm.txt in this directory for a description of
the cell format.
