[PATCH 0/3] Minor exynos7 device tree/config patches

[Abhilash Kesavan]

Patch 1 specifies the fifo sizes for UART channels on exnyos7. Without
this the 4210 compatible defaults will be picked up which are different
from that on exynos7.
Patch 2 is based on a patch from Liviu Dudau fixing a similar issue
for arm boards.
Patch 3 is needed to enable support for arm64 based exynos7 platform.

Abhilash Kesavan (2):
  arm64: dts: add fifo size property for uart channels on exynos7
  arm64: dts: Fix interrupt active level for the generic timer on
    exynos7

Alim Akhtar (1):
  arm64: Enable Exynos7 SOC in the defconfig

[PATCH 2/3] arm64: dts: Fix interrupt active level for the generic timer on exynos7

[Abhilash Kesavan]

Fix the exynos7 device tree to indicate that the arm generic timers
provide an active low interrupt output. Also, update the CPU mask to
match the number of CPUs on the SoC.
