i.MX7D SDHC SDR-140 Tuning

[daweichen]

Hi NXP,

Does i.MX7D support manual tuning (ESDHC_FLAG_MAN_TUNING)?

linux-imx source shows i.MX7D SoC is setup to use standard tuning.

i.MX7D

static struct esdhc_soc_data usdhc_imx7d_data = {

        .flags = ESDHC_FLAG_USDHC | ESDHC_FLAG_STD_TUNING

                        | ESDHC_FLAG_HAVE_CAP1 | ESDHC_FLAG_HS200

                        | ESDHC_FLAG_HS400 | ESDHC_FLAG_STATE_LOST_IN_LPMODE

                        | ESDHC_FLAG_BUSFREQ,

};

Reference source:

sdhci-esdhc-imx.c

Thanks,

Hello,

   Only the standard tuning is used and has been tested for i.MX7.
