Parameters for imx8mp HDMI pixel clock

TeroLP — Thu, 20 Jul 2023 08:33:27 GMT

linux-imx has samsung_phy_pll_cfg defined in drivers/phy/freescale/phy-fsl-samsung-hdmi.c . To support HDMI display with certain pixel clock, config struct has to have parameters for that frequency.

I'm using evalutation kit, and would need parameters for two clocks:
238760000 (2560x1440) and 150000000 (1920x1200).

I would appreciate a ready made table or a tool to generate that table.
