There are still some drivers are different with kernel, eg. 
pinctrl&GPIO, and clock driver and etc, and kernel driver also changes.

Since the gpio bank support issue has been a period, I would like to 
take one version driver at least can fix it and make U-Boot work with 
new kernel dts

and new device. The U-Boot only use small set of the devices, so we want 
to have a small enough but enough for U-Boot version driver.

So I have take this patch set, and we can improve later when kernel have 
a version and we have a better solution for U-Boot.


Thanks,

- Kever
