How to configure ipu1 and ipu2 with different clocks

[amir_e]

Hello

On imx6q, I need to configure two IPU units.

ipu1 is connected to HDMI (full HD) (148500000 hz pixel clock)

ipu2 is connected to mipi_dsi (480x800) (28278000 hz pixel clock) (taking porch+sync values into consideration)

The problem is that in the default device tree, both ipu units use the same pixel clock and divider, so when I configure a screen, the 2nd one gets misconfigured.

currently both IPUs point to the same clock, I need to configure alternative clocks for one of the IPUs.

Any suggestions on how to approach this?

Thanks,

Amir
