Hi Zhong,

Thanks for this. This driver is in the middle of cleanup and this
function is not doing all the DT parse
yet, so this patch looks good but after applying this series (if they
work and are good enough to be applied)
has no sense.

See: http://driverdev.linuxdriverproject.org/pipermail/driverdev-devel/2018-August/124890.html

Best regards,
Sergio Paracuellos
