very strange. Only in the case CONFIG_MMC_SDHCI_IPROC=m the power sequence seems to be active: [ 2.244705] sdhci-iproc 3f300000.sdhci: allocated mmc-pwrseq So after fixing the polarity of the wifi-reset everything works as expected. - reset-gpios = <&expgpio 1 GPIO_ACTIVE_HIGH>; + reset-gpios = <&expgpio 1 GPIO_ACTIVE_LOW>; I think this should be acceptable as a stable fix for 4.19 LTS.
