The patch "mmc: sdhci-of-arasan: Call OF parsing for MMC" (sha1: 16b23787fc709fe60c5d2bd05927b1a3da33d4e9) introduce new dependency on GPIOLIB which calls mmc_of_parse() -> mmc_gpiod_request_cd() (slot-gpio.c) which calls devm_gpiod_get_index() which returns -ENOSYS. Error log: sdhci-arasan ff160000.sdhci: parsing dt failed (4294967258) sdhci-arasan: probe of ff160000.sdhci failed with error -38 Signed-off-by: Michal Simek <michal.simek@xxxxxxxxxx> --- This problem is probably in all others drivers. This is one way how this can be solved. Maybe better way is to block return value for cd and wp.
It appears there is gpio code in sdhci.c as well. This uses slot-gpio. Perhaps a depends on needs to be added to MMC_SDHCI instead?
