No "qcom," in the node name.

I think we should follow Linus' lead and label this "pm8821".

Please spell out IRQ_TYPE_LEVEL_LOW.

And interrupts-extended = <&tlmm_pinmux 76 IRQ_TYPE_LEVEL_LOW> combines
the two lines nicely.

Extra newline.

I think these should be IRQ_TYPE_NONE per the discussion on how to share
interrupts between the gpio/mpp driver and other clients.

On the other hand, per the pm8821 driver we only support LEVEL_LOW
(high?).

Will fix it in next version,  I agree with rest of the comments too.
All of them will be fixed in next version.
