Do you mean I should create a new phy driver that place in "driver/phy"
directly ?
I have think about this idea, and it would make things much clean. But
INNO PHY
driver need the target pixel clock in drm_display_mode, I didn't find a
good way
to pass this variable to separate phy driver. Do you have some idea ?
Thanks,
