This patch add DT support for mxc gpio driver.
There are one place using CONFIG_OF_CONTROL macro.
- The U_BOOT_DEVICES and mxc_plat array are complied out. To DT, platdata is alloced using calloc, so there is no need to use mxc_plat.
The following situations are tested, and all work fine:
- with DM, without DT
- with DM and DT
- without DM
Since device tree has not been upstreamed, if want to test this patch. The followings need to be done.
- pieces of code does not gpio_request when using gpio_direction_xxx and etc, need to request gpio.
- move the gpio settings from board_early_init_f to board_init
- define CONFIG_DM ,CONFIG_DM_GPIO and CONFIG_OF_CONTROL
- Add device tree file and do related configuration in `make ARCH=arm menuconfig`
These will be done in future patches by step.
