Tested on my mickey board with chrome os on kernel 4.4 -rc3.
localhost / # cat /proc/version
Linux version 4.4.0-rc3+ (wxt at ubuntu) (gcc version 4.6.x-google 20120106
(prerelease) (GCC) ) #59 SMP Thu Dec 3 17:32:10 CST 2015
.....but,
reboot long long test, that's seem mmc tune has a issue.
2.630892] mmcblk0: error -84 transferring data, sector 0, nr 8, cmd
response 0x900, card status 0x0
[ 2.631006] mmcblk0: error -110 sending status command, retrying
[ 2.631018] mmcblk0: error -84 transferring data, sector 1, nr 7, cmd
response 0x900, card status 0x0
[ 2.631703] mmcblk0: unable to read partition table
...
Anyway, the dts is good to support mickey machine.
I think the mmc tune is not prefect in mainline.
