[RFC PATCH 0/4] Add RGB ttl connection on rockchip phy

[Michael Trimarchi]

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 some register that are used to enable
the TTL, are in the same register area of the dsi controller.
In order to test I must add the following

dsi_dphy: phy at ff2e0000 {

	reg = <0x0 0xff2e0000 0x0 0x10000>,
		<0x0 0xff450000 0x0 0x10000>;
	...
}

The problem here is the second region I have added is the same of
dsi logic. Only one register is needed by the the phy driver
