I'd like to somehow keep the SoC-specific code out of this driver.
You've done a nice job separating it out, but I wonder if we can go a
bit further.

I'm thinking of perhaps having two vop drivers, one for rk3288 and one
for rk3399. They can share most of the operations (e.g. bind()) which
can stay in the existing rk_vop.c file. For probe() you can rename the
existing probe() function to something like rockchip_vop_probe(), and
pass it the device and a rkvop_driverdata *.

Does that make sense? Then when we add more chips we'll have a small
extra file with the SoC-specific functionality.

Also please put the plat->size change in its own patch.

Regards,
Simon
