Subject: Re: [PATCH RFC 0/6] Add QCOM pwm-lpg and tri-led drivers

Hi,

Dalsi cech co hackuje LEDky?

Nie. Slovak.

Bindings should go first, they may need to be converted to yml
(devicetree people will know).

OK

Can generic pwm driver be used here?

I have not tried to do that. But considering it's custom chip from
Qualcomm then it's unlikely.

This is for RGB modules, right? It will need to use multicolor
framework.

This is for RGB LEDs in phones that are connected via pmic.

Is this for phone, btw? If so, which one?

Yes it is. And it's for many many phones actually. I have done this
mainly for SONY phones (Xperia 10, 10 Plus, XA2, XA2 Plus, XA2 Ultra).
All of them use these drivers for generating the PWM and controlling the LEDs.

P.S resending because i sent it as HTML apparently.
Best Regards,
Martin
