[PATCH v10 0/7] arm: Add basic support for Mediatek Cortex-A7 SoCs

[Matthias Brugger]

Tenth round for the Mediatek basic support patches.

The main change is the return of IOMEM_ERR_PTR in case of error in
of_io_request_and_map.
The call follows the same logic as devm_ioremap_resource.

For the changes of the of_io_request_and_map patch I deleted the ack from Grant Likely, as the patch changes significantly.
In the case of the dt bindings for the timer I left the ack lines from Soeren and Rob. I hope there is no problem with that.

This patch set adds basic support for the Mediatek Cortex-A7 SoCs.
Support is quite basic, as the only component working up to now are the
timers.

The patch series is build against tag v3.16-rc1 from torvalds/master tree.
