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.
