Since the mmc module on bcm2835 neither provide a capabilities register nor free documentation we must rely on the downstream implementation [1]. So enable the following capabilities for bcm2835: MMC_CAP_MMC_HIGHSPEED MMC_CAP_SD_HIGHSPEED MMC_CAP_DRIVER_TYPE_A MMC_CAP_DRIVER_TYPE_C [1] - https://github.com/raspberrypi/linux/blob/rpi-4.4.y/drivers/mmc/host/bcm2835-mmc.c Signed-off-by: Stefan Wahren <stefan.wahren@xxxxxxxx> --- drivers/mmc/host/sdhci-iproc.c | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) diff --git a/drivers/mmc/host/sdhci-iproc.c b/drivers/mmc/host/sdhci-iproc.c index d7046d6..30b3fdf 100644 --- a/drivers/mmc/host/sdhci-iproc.c +++ b/drivers/mmc/host/sdhci-iproc.c @@ -211,14 +211,17 @@ static void sdhci_iproc_writeb(struct sdhci_host *host, u8 val, int reg) static const struct sdhci_pltfm_data sdhci_bcm2835_pltfm_data = { .quirks = SDHCI_QUIRK_BROKEN_CARD_DETECTION | SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK | - SDHCI_QUIRK_MISSING_CAPS, + SDHCI_QUIRK_MISSING_CAPS | + SDHCI_QUIRK_NO_HISPD_BIT, .ops = &sdhci_iproc_32only_ops, }; static const struct sdhci_iproc_data bcm2835_data = { .pdata = &sdhci_bcm2835_pltfm_data, - .caps = SDHCI_CAN_VDD_330, - .caps1 = 0x00000000, + .caps = SDHCI_CAN_VDD_330 | + SDHCI_CAN_DO_HISPD, + .caps1 = SDHCI_DRIVER_TYPE_A | + SDHCI_DRIVER_TYPE_C, .mmc_caps = 0x00000000, }; -- 1.7.9.5 -- 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
