[PATCH] arm64: dts: qcom: msm8998-mtp: Increase load on l21 for sdcard

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



l21 is used as sdcard vmmc, and needs the load increased to prevent
voltage drop issues with some sdcards.  This addresses -84 errors seen
during sdcard init with SDR104 cards.
