Hi Fabio,
Subject: [PATCH] ARM: dts: imx8mq-evk: Remove u-boot,off-on-delay-us property
Commit 247bbeb74c18 ("ARM: dts: imx8m: increase off-on delay on the SD Vcc regulator") caused the imx8mq-evk board to not be able to store the environment variables in the SD card.
Remove the u-boot,off-on-delay-us property to fix the regression.
It is board dependent, some board may has a big capacitance, the off-on-delay is to give enough time for the capacitance to leak its voltage.
Regards, Peng.
