[PATCH v5 0/8] arch: arm64: Enable support for Samsung Exynos7 SoC

[PATCH v5 0/8] arch: arm64: Enable support for Samsung Exynos7 SoC

[Abhilash Kesavan]

Changes since v4:
- Fixed comments from Tomasz Figa:
	- Changed the namespace prefix from exynos to samsung
	- Defined bindings to take all input clocks
	- Sorted the Kconfig entries alphabetically in clock Makefile
	- Used consistent 1 tab line breaks across the clock file
	- Statically initialized the samsung_cmu_info struct
- Enabled exynos7 in the arm64 defconfig as per Catalin Marinas' comment.
- Added Kukjin Kim's ack along with Thomas Abraham's tested and reviewed tags.

Changes since v3:
- Removed aliases for serial controllers from dtsi file and moved it
  into board specific dts file as suggested by Arnd.
- Based this series on Robert Richter's patches for adding vendor
  device tree sub-directories for arm64.
  http://comments.gmane.org/gmane.linux.kbuild.devel/12131

This patchset supports the new Exynos7 Samsung SoC based on Cortex-A57.
Exynos7 is a System-On-Chip (SoC) that is based on 64-bit ARMv8 RISC
processor.

The following patches are tested based on linux-next tree (20140919).
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/

Following patches are required for this series:
1- "tty/serial: fix config dependencies for samsung serial"
   https://www.mail-archive.com/linux-samsung-soc <at> vger.kernel.org/msg36208.html
2- "dts, kbuild: Implement support for dtb vendor subdirs" patchset 
   http://comments.gmane.org/gmane.linux.kbuild.devel/12131

Alim Akhtar (2):
  arm64: exynos7: Enable ARMv8 based Exynos7 (SoC) support

I've picked up patches from the $subject series.  But please see my
comment the the second series you've pointed out with the link above.
If you decide to rearrange changes to exynos7-clk.h header file among
those two series I will drop that 4 patches.  Perhaps you could gather
all pending exynos7 clk patches, fix any issues and send to me in one
series ?
I'd like to avoid modifying indices assigned to specific clocks in
subsequent patches, DT binding should be defined in advance and ideally
be specifying exact indices for each possible clock.

Sylwester, you mentioned in another thread that Tomasz might not be
available for the next few days. Could you please consider applying
the clock changes in this series to samsung clk-next if they look OK ?

Please take a look at clock changes at

I'd like to do so. Kukjin, since clock changes are a part of this
series, might I have your Ack for them to be applied separately?

The arch changes look fine to me (not much in there, just Kconfig,
defconfig, Makefile). Regarding the dts, I'd like to see some acks from
the DT or arm-soc maintainers.

BTW, the arch/arm64/ patches in your series should be merged via the
arm-soc tree (Arnd/Olof, cc'ing them now).

Maybe you make this patch on top of the Robert's patch.
As I know, Robert's patch is not yet merged in mainline.
You should specify this dependency in mail thread.

The clock patches look good to me, but since they are doing quite a lot
of code moving I'd prefer to take them through clk tree. Based on the
fact that there are no code dependencies between clock patches and
remaining ones and Exynos7 is a new material for 3.18, I'm inclined to
apply them to my tree if nobody minds.

Best regards,
Tomasz

[PATCH v5 0/8] arch: arm64: Enable support for Samsung Exynos7 SoC

[Abhilash Kesavan]

Changes since v4:
- Fixed comments from Tomasz Figa:
	- Changed the namespace prefix from exynos to samsung
	- Defined bindings to take all input clocks
	- Sorted the Kconfig entries alphabetically in clock Makefile
	- Used consistent 1 tab line breaks across the clock file
	- Statically initialized the samsung_cmu_info struct
- Enabled exynos7 in the arm64 defconfig as per Catalin Marinas' comment.
- Added Kukjin Kim's ack along with Thomas Abraham's tested and reviewed tags.

Changes since v3:
- Removed aliases for serial controllers from dtsi file and moved it
  into board specific dts file as suggested by Arnd.
- Based this series on Robert Richter's patches for adding vendor
  device tree sub-directories for arm64.

This patchset supports the new Exynos7 Samsung SoC based on Cortex-A57.
Exynos7 is a System-On-Chip (SoC) that is based on 64-bit ARMv8 RISC
processor.

The following patches are tested based on linux-next tree (20140919).
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/

Following patches are required for this series:
1- "tty/serial: fix config dependencies for samsung serial"
   https://www.mail-archive.com/linux-samsung-soc <at> vger.kernel.org/msg36208.html
2- "dts, kbuild: Implement support for dtb vendor subdirs" patchset
