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@xxxxxxxxxxxxxx> Cc: stable@xxxxxxxxxxxxxxx Link: https://lore.kernel.org/r/20200416183513.993763-2-martin.blumenstingl@xxxxxxxxxxxxxx Signed-off-by: Ulf Hansson <ulf.hansson@xxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/mmc/host/meson-mx-sdio.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/drivers/mmc/host/meson-mx-sdio.c +++ b/drivers/mmc/host/meson-mx-sdio.c @@ -570,7 +570,7 @@ static int meson_mx_mmc_add_host(struct mmc->f_max = clk_round_rate(host->cfg_div_clk, clk_get_rate(host->parent_clk)); - mmc->caps |= MMC_CAP_ERASE | MMC_CAP_CMD23; + mmc->caps |= MMC_CAP_ERASE | MMC_CAP_CMD23 | MMC_CAP_WAIT_WHILE_BUSY; mmc->ops = &meson_mx_mmc_ops; ret = mmc_of_parse(mmc); Patches currently in stable-queue which might be from martin.blumenstingl@xxxxxxxxxxxxxx are queue-5.4/mmc-meson-mx-sdio-set-mmc_cap_wait_while_busy.patch queue-5.4/mmc-meson-mx-sdio-remove-the-broken-card_busy-op.patch
