Subject: [PATCH] ARM: dts: rockchip: Make rk3288-veyron-minnie run at hs200
Date: Fri, 3 May 2019 16:41:42 -0700 [thread overview]
Message-ID: <20190503234142.228982-1-dianders@chromium.org> (raw)
As some point hs200 was failing on rk3288-veyron-minnie. See commit
984926781122 ("ARM: dts: rockchip: temporarily remove emmc hs200 speed
from rk3288 minnie"). Although I didn't track down exactly when it
started working, it seems to work OK now, so let's turn it back on.
To test this, I booted from SD card and then used this script to
stress the enumeration process after fixing a memory leak [1]:
cd /sys/bus/platform/drivers/dwmmc_rockchip
for i in $(seq 1 3000); do
echo "========================" $i
echo ff0f0000.dwmmc > unbind
sleep .5
echo ff0f0000.dwmmc > bind
while true; do
if [ -e /dev/mmcblk2 ]; then
break;
fi
sleep .1
done
done
It worked fine.
