It appears there is gpio code in sdhci.c as well. This uses slot-gpio.

Anyway I am happy to send v2 with GPIOLIB dependency for the whole MMC subsystem.

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.
