i tried to connect 88W8787 to sd2 of imx6q.
static const struct esdhc_platform_data mx6q_sabresd_sd2_data __initconst = {
//.cd_gpio = SABRESD_SD2_CD,
//.wp_gpio = SABRESD_SD2_WP,
.keep_power_at_suspend = 1,
.support_8bit = 0,
.delay_line = 0,
.cd_type = ESDHC_CD_PERMANENT,
.runtime_pm = 1,
};
after insmod wifi-sdio,ko:

looks like firmware download was succeed after loading my wifi-sdio.ko,
but waht's that meaning 'read mp_regs failed'?
