wandboard: Fix hang when going into low frequency A kernel hang is observed when running wandboard 3.14 kernel and going to the lowest operational point of cpufreq: # ifconfig eth0 down # echo 1 > /sys/class/graphics/fb0/blank The problem is caused by incorrect setting of the REFR field of register MDREF. Setting it to 4 refresh commands per refresh cycle fixes the hang. Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com>
