Oct. 24, 2022, 3:13 a.m. UTC
From: Peng Fan <peng.fan@nxp.com> Some SD Card controller and power circuitry has increased capacitance, so the usual toggling of regulator to power the card off and on is insufficient. According to SD spec, for sd card power reset operation, the sd card supply voltage needs 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. This patch add the off-on-delay-us, make sure the sd power reset behavior is align with the specification. Without this patch, when do quick system suspend/resume test, some sd card can't work at SD3.0 mode after system resume back.
