Add more n/cts values, in that case we can support audio for more display resolutions (128 * SampleRate = PixelClock * N / CTS).
Where do these come from? The iMX6 manuals give the set which are already in the driver, and says that others are not supported - to quote...
"Table below shows the CTS and N values for the supported standard. All other TMDS clocks are not supported, the TMDS clocks divided or multiplied by 1,001 coefficients are not supported."
and the table lists values for TMDS clocks of 25.2, 27, 54, 74.25, 148.5 and 297MHz.
This will need to be tested on iMX6 to validate whether it works. If it doesn't work, we need to conditionalise the new TMDS clocks with the IP version.
I just want to add audio support for some No-CEA display resolutions, and actually it can works on rk3288 platform. If it can not work on iMX6 platform, i will add IP verison select in next version v3.
Thanks. : )
