Hi Thomas, Daniel,

Sure this driver should have a cleanup, but it still depends on old legacy vexpress calls.

The reason I submitted a change and a small cleanup over this driver is because the high
similarities of the HW and avoiding adding a brand new driver cloning much of its
functionalities.

I propose to study an eventual cleanup, but could this change be submitted for 4.7 since
it's part of a base platform support serie ?

Thanks,
Neil
