Add support for the Rockchip W552793DBA-V10 LCD+touchscreen assembly which
comes physically attached to Rockchip RK3576 EVB1 boards.
The display part is driven by the on-chip MIPI DSI controller, and the
touchscreen is connected over I2C.

Note that backlight support is left out for now, as it depends on PWM
support [0] which has not yet been merged.
A workaround is simply `gpioset -c 0 13=1` to set the respective GPIO
pin high and thus to light up the display unconditionally.

Hi Heiko,
Any thoughts about this one? Can we perhaps get it merged for -next?
Thanks a lot,

Does the gpio-backlight work on that device?
That would make the gpioset hack unnecessary.

I've got a local patch using pwm-gpio and pwm-backlight as a stop-gap
solution, but I don't think it's worth merging upstream, because the
backlight is supposed to be driven by the hardware PWM on the same pin
(not bit-banging the GPIO line). After all, Nicolas has been working on
adding a proper hardware PWM driver for RK3576.
The display itself works without PWM support, and so does the touchscreen.
My temp patch goes like this:

Right now, I don't think we have an actual timeline if/when Nicolas will
be able to work on the pwm again. So my idea was if we want to
integrate the baclight as you described below, to have an actual usable
display and then when the new pwm has landed switch over to that one?

Soon(TM), I've locally reworked the PWM output stuff and core driver
into an MFD. I just need to rework the counter driver now and set up
a proper way to test that the counter works.
I'm hoping to have something next week. If not, then the week after
that.

But Heikooooo, DTs should describe hardware, not the lack of Linux
drivers! ;)
For what it's worth, the implementation move to MFD didn't change the
bindings as we don't leak that into the DT at all. If it took any
longer for me to get it done I'd have suggested picking the bindings
and then adding a stub GPIO PWM driver that binds to it as an interim
solution, but it's not worth the ickyness when I'm basically just
a day's work away from having this done.
