bridge is not powered off until atomic_post_disable is called. This

Hi all,
Are there any thoughts or comments about this proposal?

Dispite the commit 1f0f015151727, the rgb output has an option
to allow to sent the output pin using the dsi/lvds/ttl logic.
The only way to do and stay on the same design is let the
rockchip_rgb block to grab the handle if it is present and
enable it. The present of this handle depends on dts
The function is used to avoid to enable clock on the hardware
if the mode requested is invalid

The rockchip phy can be programmed in 3 modes:
- dsi
- lvds
- ttl
For instance in px30 there are two sets of rgb interface pins m0 and m1.
The logic can go outside from the VOP using m0 set or go outside using
the m1 set and the ttl logic enable. There are combination where a set
of pin can be
There are combo phys out there that can be switched between doing
dsi, lvds, and ttl. So add a mode definition for it.

The rockchip phy can be convigured in ttl mode. The phy is shared
between lvds, dsi, ttl. The configuration that now I'm able to support
has the display output on some set of pins on standard vop output
and a set of pins using the ttl phy. The solution is not clean as I
would like to have because
