Fabio Estevam b82fe6ddd7 video: fbdev: imxfb: Provide a reset mechanism ... Currently when we boot the kernel on a mx25pdk the LCDC controller does not show the Linux logo on boot. This problem is well explained by Sascha Hauer: "Unfortunately this LCD controller does not have an enable bit. The controller starts directly when the clocks are enabled. If the clocks are enabled when the controller is not yet programmed with proper register values then it just goes into some undefined state. What I suspect is that the clocks already were enabled before driver probe, presumably by the bootloader, so the controller is already in undefined state when entering Linux. Now by dis/enabling the ipg clock you effectively reset the controller. Since you have programmed it with valid register values in the mean time it starts working after this reset." So do as suggested and force a reset of the LCDC hardware by enabling and disabling the IPG clock. With this change the Linux logo can be seen on boot on a mx25pdk.
