I can remove it when applying the patch, just want to make sure all review comments are addressed - only the suspend thing it seems. Thanks Heiko

That is correct, but let me send a v2 of this instead. I'll remove this verbiage among other fixes. End users wanted me to see if I could get this panel to run at precisely 60hz, which I believe I am able to do with the addition of a new PLL clock in clk_rk3568. I believe I have taken every constraint detailed in the datasheet to heart for the new frequency I'll be requesting. By using the frequency of 292500000 for the VPLL I can get the panel running at 59.969hz which in my view is close enough to the ideal 59.98hz. I also accidentally left the UART2 active even though this device has no exposed UART port, so I need to fix that too by disabling it. Lastly I'll add my tested by to the dri-devel patches as well.
