From: Haibo Chen <haibo.chen@xxxxxxx> V3: - involve init_card() callback instead of change the common code. V2: - drop the dts/dt-binding change, since this is one IC limitation, so handle this directlly in driver. - simply the auto tuning code logic. - To detect the SDIO device in host driver side, add some change in common code, move host->card = card a bit upper. Haibo Chen (2): mmc: sdhci-esdhc-imx: simplify the auto tuning logic mmc: sdhci-esdhc-imx: only enable DAT[0] and CMD line auto tuning for SDIO device drivers/mmc/host/sdhci-esdhc-imx.c | 66 ++++++++++++++++++++++++++---- 1 file changed, 57 insertions(+), 9 deletions(-) -- 2.34.1
