Re: Dual lvds with different frequencies

Hi,
we can reproduce the blank/unblank behavior on latest Rocko BSP.
We suspect we inherited this behaviour from original NXP kernel.
Can you please consider switching to our customer portal

Thanks

Re: Dual lvds with different frequencies

Hi,
is this behavior reproducible also with Yocto Morty (after patching the device tree)?

Re: Dual lvds with different frequencies

Sorry, but I did not understand the test sequence.
Do you mean that the 2 LVDS start with different clocks and than change to use the same frequency?
If yes, what is triggering the change?
Can you please elaborate?

Re: Dual lvds with different frequencies

So, even if you connect only the 51MHz LCD, the debug messages always say that the rounded clock is 40MHz, correct?

Re: Dual lvds with different frequencies

Hi,
thanks for the logs.
What happens to the logs if you only declare the bigger LCD?
Always 40 MHz?

Re: Dual lvds with different frequencies

Hi, from your debug output, I can see that the clock setting is correctly received by the ipu driver, but somehow the clock is "rounded" to 39999999 in both the cases. It looks that the problem is not relates to the dts, but to the clock tree: most likely, if you swap the display order, yo...
