Note: Gustavo Padovan try to remove the controller and phy power on function in bind time at bellow commit: drm/exynos: do not start enabling DP at bind() phase But for now the connector status don't hardcode to connected, need to operate dp phy in .detect function, so we need to revert parts if Gustavo Padovan's changes, add phy poweron function in bind time. Signed-off-by: Yakir Yang Tested-by: Javier Martinez Canillas --- Changes in v13: None Changes in v12: None Changes in v11: - Revert parts of Gustavo Padovan's changes in commit: drm/exynos: do not start enabling DP at bind() phase Add dp phy poweron function in bind time. - Move the panel prepare from get_modes time to bind time, and move the panel unprepare from bridge->disable to unbind time.
