Hello, Sascha, I have following 3 comments to this patch: 1) I think DISP1_DATx pins need not be set specially, as they keep the default register values.We do not want to depend on default register values in the Linux Kernel.
[LY] Ok. Please add disp1 related pins configuration, including
DISP1_HSYNC, DISP1_VSYNC and DISP1_CLK.
It will be fine to add disp2 related pins configuration also.quoted
2) Please define 'MX51_PAD_DI_GP4__IPU_DI2_PIN15' in arch/arm/plat-mxc/include/mach/iomux-mx51.h, and rename the pin to be 'MX51_PAD_DI_GP4__DI2_PIN15', as we name it according to the MX51 iomux reference manual.I'm not sure. Normally it's good practice to code the unit into the name. Otherwise we end up with names like MX51_PAD_xyz__TX which could be the tx pin of just about any unit.quoted
3) It is better to exchange the following two lines or just remove the first line: + gpio_set_value(GPIO_DVI_RESET, 0); + gpio_direction_output(GPIO_DVI_RESET, 0);ok.
