mmc: meson-mx-sdio: Set MMC_CAP_WAIT_WHILE_BUSY
The Meson SDIO controller uses the DAT0 lane for hardware busy detection. Set MMC_CAP_WAIT_WHILE_BUSY accordingly. This fixes the following error observed with Linux 5.7 (pre-rc-1): mmc1: Card stuck being busy! __mmc_poll_for_busy blk_update_request: I/O error, dev mmcblk1, sector 17111080 op 0x3:(DISCARD) flags 0x0 phys_seg 1 prio class 0 Fixes: ed80a13bb4c4c9 ("mmc: meson-mx-sdio: Add a driver for the Amlogic Meson8 and Meson8b SoCs") Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20200416183513.993763-2-martin.blumenstingl@googlemail.com Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
