Hi!

Quoted 6 lines

We have used leds-pwm driver to control led in some mediatek IC, but
we have some further requirement, and want to add some common functions for this driver, could you give us some suggestions?
For dts, we want to add led-bits and trans-bits, led-bits represents
the led bits(8->255, 10->1023) from user space, trans-bits represents the led hardware IC bits.

First, please make sure there is no existing functionality that can be used. If not, please use something like "max brightness", not bits.

Quoted 4 lines

For function, we want to add led event notify, one event is for led
brightness change, the other one is for led shutdown.
We also want to add setMaxBrightness function and setLedBrightness
function for other module to call.

Umm. No?

Best regards,

Pavel
