[PATCH v3 0/7] arm: mediatek: Add more basic features

[Matthias Brugger]

This patch set adds some minor changes to the Mediatek mt6589 support.

Features are low-level debugging on the mt6589, the addition to the
"make dtbs" and multi_v7_defconfig, earlyprintk suppport, as well as a small
changes in the DTS files.

The patch set is based on v3.17-rc1

Changes for v3:
- drop quirk to enable ARM arch timer

Changes for v2:
- rebased on v3.17-rc1
- add patch for the compatible property of aquaris5
- add patch setting GIC compatible string to new "arm,cortex-a7-gic"
- set ARM arch timer frequency in DTS
