It is necessary to set PLL CLK and other CLK when select the custom resolution HDMI output. I put the question to amlogic because I don’t understand the register of CLK, but need to wait for it.
I list the question in this post and hope some people can give me some advices.
##The question list:
##1. How to add the configuration for custom resolution ?
##2. How to set the P_HHI_HDMI_PLL_CNTL register ?
##3. Is it necessary to reset the P_HHI_HDMI_PLL_CNTL3 register for custom resolution ?
