Switch to DM_GPIO and add gpio_request where necessary. This is needed for DM_VIDEO and fixes an issue with sd card detection which was introduced by the combination of these commits: commit7a0425dd96("mmc: fsl_esdhc: make get_cd work well in dm_mmc_ops") commit7e04b4c751("dm: arm: imx: migrate cx9020 to CONFIG_DM_MMC") Acked-by: Patrick Bruenn <p.bruenn@beckhoff.com> Signed-off-by: Steffen Dirkwinkel <s.dirkwinkel@beckhoff.com>
