Hello,
we are in the process of porting software from Android 9 to Android 11, which has been necessary due to a hardware change in the carrier board we are supplied with for a Variscite iMX8M (which apparently is based on imx8mq evk)
For Android 9 we had a solution working on 1280x800 32bpp 70.875MHz pixel clock based on the "HDMI calculation tool" xlsx file. However Android 11 now uses Kernel 5.x.y instead of Kernel 4.x.y, which has means a lot of chances to the gpu and drm subsystem.
Therefore we cannot take the old values anymore. Is there an updated spread sheet available for calculating the new values to be put into cdns-mhdp-hdmi-phy.c?
What would we need to change in order to get the pll tuning correct to output 70.875MHz which we know the hardware is capable of or better 71.000MHz, which is what the edid for our screen says we should supply?
