Without this commit the SD card (auto-)detection fails when booted from this sd-card: mmc1: Query interface conditions failed: -110 mmc1: SD operation condition set timed out The commit is ported from U-Boot: | commit 247bbeb74c186963d9365db3136d0285618bd9a7 | Author: Andrey Zhizhikin | Date: Sat Dec 5 17:29:17 2020 +0000 | | ARM: dts: imx8m: increase off-on delay on the SD Vcc regulator | | Some SD Card controller and power circuitry has increased capacitance, | which keeps the internal logic remains powered after regulator is switch | off. This is generally the case when card is switched to SD104 mode, | where a power cycle should be performed. In case if the card internal | logic remains powered, it causes a subsequent failure of mode | transition, effectively leading to failed enumeration. | | Introduce a delay of 20 msec in order to provide a possibility for | internal card circuitry to drain voltages and perform a power cycle | correctly. | | Similar fix is done in commit c49d0ac38a76 ("ARM: dts: rmobile: Increase | off-on delay on the SD Vcc regulator") targeted Renesas SOCs. | | Signed-off-by: Andrey Zhizhikin | Cc: Stefano Babic Signed-off-by: Marco Felsch --- arch/arm/dts/imx8mp-evk.dts | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/arch/arm/dts/imx8mp-evk.dts b/arch/arm/dts/imx8mp-evk.dts index 3264ade4b8..77b438287c 100644 --- a/arch/arm/dts/imx8mp-evk.dts +++ b/arch/arm/dts/imx8mp-evk.dts @@ -35,6 +35,10 @@ reset-deassert-us = <100000>; }; +®_usdhc2_vmmc { + off-on-delay-us = <20000>; +}; + &usdhc2 { #address-cells = <1>; #size-cells = <1>; -- 2.30.2
