Our customer have a question about i.MX6DQ HDMI.
They want to know how to use HDMI RGB limited range (level 16 to 235) to MHL output.
(MHL requires RGB limited range)
I checked MCIMX6DQRM (Rev.3), and understood HDMI module supports limited range.
But did not understand how to set the registers to use RGB limited range.
Should we use the equation written in chapter 33.4.5 in IMX6DQRM Rev.3?
Or is it possible by YQ1_YQ0_YCC field in HDMI_FC_AVICONF3 register(Chapter 33.5.70)?
