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. --- drivers/mmc/host/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/mmc/host/Kconfig b/drivers/mmc/host/Kconfig index fd9a58e216a5..4b5854759cfc 100644 --- a/drivers/mmc/host/Kconfig +++ b/drivers/mmc/host/Kconfig @@ -120,6 +120,7 @@ config MMC_SDHCI_PLTFM config MMC_SDHCI_OF_ARASAN tristate "SDHCI OF support for the Arasan SDHCI controllers" depends on MMC_SDHCI_PLTFM + depends on GPIOLIB depends on OF help This selects the Arasan Secure Digital Host Controller Interface -- 2.3.5 -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
