[PATCH v7 0/7] Enable support for Samsung Exynos7 SoC

[PATCH v7 0/7] Enable support for Samsung Exynos7 SoC

[Abhilash Kesavan]

These were originally part of 2 patchsets[1][2] adding support for Exynos7.
 The clock and pinctrl patches are going through the respective maintainer's
tree; hence the remaining dt related patches have been consolidated and are
being posted here as a separate series.

This patchset has build dependencies on the following patches:
a] "[GIT PULL] Samsung clock changes for 3.19" - specifically the clock dt
   bindings header.
   http://comments.gmane.org/gmane.linux.kernel.samsung-soc/39142
b] "tty: serial: samsung: Clean-up selection of number of available UARTs"
   http://www.spinics.net/lists/linux-samsung-soc/msg37418.html
c] "dts, kbuild: Implement support for dtb vendor subdirs"(merged in linux-next)
   https://lkml.org/lkml/2014/10/21/654

[1] arch: arm64: Enable support for Samsung Exynos7 SoC
http://www.spinics.net/lists/linux-samsung-soc/msg37047.html
[2] Add clock and DT support for a few IPs on Exynos7
http://www.spinics.net/lists/linux-samsung-soc/msg37973.html

Changes since v6:
	- Fixed the platform ordering (exynos before thunder) in Kconfig file.
	- Fixed the ordering of reg and enable-method properties in cpu node
	as per Lorenzo Pieralisi's comment.

Abhilash Kesavan (2):
  arm64: dts: Add PMU DT node for exynos7 SoC
  arm64: dts: Add nodes for mmc, i2c, rtc, watchdog, adc on Exynos7

Alim Akhtar (2):
  arm64: exynos7: Enable ARMv8 based Exynos7 (SoC) support
  arm64: Enable Exynos7 SOC in the defconfig

Naveen Krishna Ch (2):
  arm64: dts: Add initial device tree support for EXYNOS7
  arm64: dts: Add initial pinctrl support to EXYNOS7

Pankaj Dubey (1):
  arm64: dts: add <dt-bindings/> symlink

[PATCH v7 1/7] arm64: dts: add <dt-bindings/> symlink

[Abhilash Kesavan]

From: Pankaj Dubey <pankaj.dubey@samsung.com>

Add symlink to include/dt-bindings from arch/arm64/boot/dts/include/ to
match the ones in ARM architectures so that preprocessed device
tree files can include various useful constant definitions.

See commit c58299aa8754 ("kbuild: create an "include chroot" for DT bindings")
merged in v3.10-rc1 for details.
