Problems after recent changes to meson-gx-mmc driver

[hkallweit1@gmail.com (Heiner Kallweit)]

Hi Jerome,

the recent changes, most likely one of the changes affecting the clock phase setting
or tuning, break mmc on my system (Odroid C2 + Hardkernel 128GB eMMC card).
"Next" kernel from Aug 25th works fine here. Hadn't time yet to bisect the issue.

As additional info, that's what the eMMC DT config looks like here.
The issue remains when switching to HS200.

/* eMMC */
&sd_emmc_c {
        status = "okay";
        pinctrl-0 = <&emmc_pins>;
        pinctrl-names = "default";

        bus-width = <8>;
        cap-sd-highspeed;
        max-frequency = <200000000>;
        non-removable;
        disable-wp;
        cap-mmc-highspeed;
        mmc-ddr-1_8v;
        mmc-hs400-1_8v;

        mmc-pwrseq = <&emmc_pwrseq>;
        vmmc-supply = <&vcc3v3>;
        vqmmc-supply = <&vcc1v8>;
};

Kind regards,
Heiner
