[PATCH v7 0/7] arm: Add basic support for Mediatek Cortex-A7 SoCs

[Matthias Brugger]

Seventh round for the Mediatek basic support patches.

Due to the discussion about the need of request the memory needed by a
device [0], I implemented the function of_io_request_and_map.
The clocksource drivers uses proper error handling and keep on booting
the device instead of calling panic.

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 torvalds/master tree.
