[PATCH v2 0/2] Add mt6795 basic chip support

[PATCH v2 0/2] Add mt6795 basic chip support

[Mars Cheng]

This patch adds basic chip support for Mediatek 8-core chip, mt6795.
It is also named as Helio X10. It is based on:
1. 4.2-rc1
2. [PATCH v4 0/2] Add mt6580 basic chip support

The second one has added some device tree binding documentation for
mt6580. mt6795 has some device tree binding modifications too.
To cleanly apply this patch, please apply mt6580 patch set first.

Changes in v2
1. Remove clocks node & bootargs
2. Refine stdout-path setting
3. Use correct mask value in device tree for arm local timer

Hi all

Need anything to get this patch reviewed?
If there is anything to do, I will do my best to finish it.

Thanks a lot.

Your series is not based on v4.2-rc1, anyway I fixed it and applied to v4.2-
next/arm64

Thanks.
