Hi Anatolij,
I noticed that after mxsfb has been converted to DM the lcdif_power_down() function is no longer called.
This causes issues in the kernel, where the Linux logo sometimes appears in the incorrect position, for example. I see this issue on a imx6ul-evk board.
If I do the same steps of U-Boot lcdif_power_down() inside the mxsfb driverl I can make the logo to always appear in the correct position, but in order to avoid regressions when booting existing kernels I think that lcdif_power_down() still needs to be called when DM_VIDEO is selected.
Not sure how to do this cleanly though.
Or in other words:
How do we make the .remove hook from the mxs_video driver to be invoked prior to booting the kernel?
Thanks
