If anyone has any objections, please let me know. ------------------ From: Haibo Chen [ Upstream commit ca643894a37a25713029b36cfe7d1bae515cac08 ] For SD card, according to the spec requirement, for sd card power reset operation, it need sd card supply voltage to be lower than 0.5v and keep over 1ms, otherwise, next time power back the sd card supply voltage to 3.3v, sd card can't support SD3.0 mode again. To match such requirement on imx8qm-mek board, add 4.8ms delay between sd power off and power on.
