[PATCH v4 0/3] about data busy
From: Addy Ke
Date: Sat Feb 14 2015 - 01:18:36 EST
patch 1: This patch can fix bug that controller is still data busy after
reset all blocks. After this patch, I still get data busy in
patch 2: This patch fix bug 'Timeout sending command'. After patch1 and
patch2, there is no mmc errors after:
for i in $(seq 1 10000); do
echo "========================" $i
echo ff0c0000.dwmmc > unbind
echo ff0c0000.dwmmc > bind
patch3: This patch fix bug that there is data busy before sdio send CMD53.
But This patch is necessary for sd and mmc too.
Addy Ke (3):
mmc: dw_mmc: update clock after host reach a stable voltage
mmc: dw_mmc: fix bug that cause 'Timeout sending command'
mmc: dw_mmc: Don't start command while data busy
