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 <redacted> --- drivers/mmc/host/sdhci-iproc.c | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-)
