  - Direct Rendering Manager (DRM)
  - DRM bridge registration and lookup framework
  - Parade ps8622/ps8625 eDP/LVDS bridge
  - NXP ptn3460 eDP/LVDS bridge
  - Exynos Fully Interactive Mobile Display controller (FIMD)

 This patch is needed to have display working on many Exynos boards.
 
OK, I'll apply this into samsung tree in this weekend.

Thanks for your gentle reminder.

- Kukjin

 $subject enables the config option for the ps8622/ps8625 eDP/LVDS
 bridge driver but this has not landed in mainline yet. Ajay will
 re-spin a new revision of his series that adds this driver though,
 after addressing some issues pointed out on a previous version.
 
 The Kconfig symbol name (DRM_PS8622) won't change though so maybe is
 not crazy to pick the patch as is since CONFIG_DRM_PS8622 will have to
 be enabled later when the bridge driver lands. Or do you want me to
 re-spin $subject removing that option?
 
 Best regards,
 Javier

 The option CONFIG_EXYNOS5420_MCPM is causing imprecise external aborts
 during boot testing, causing various userspace startup failures.
 
 Disable until it has gotten more testing.

 This has been reported by a few people[1], but not investigated or fixed, so 
 it's
 time to disable this feature until it can be fixed.
 
Hi Kevin,

Yeah I agree with your opinion.

But as you can see my tree, I've queued regarding mcpm patches for 3.19 will
be shown in -next in this weekend. Anyway let me apply this into -fixes and
then let's enable after test its functionality in -next in a couple of days.

Thanks,
Kukjin

  I think it is wrong. The released bootloader from Samsung is not u-boot.
  Instead, you have to update u-boot to support Exynos3250-basd Rinato board.
 
 The bootloader on device also was not a u-boot. So the fix is for native
 bootloader delivered on device.
 
 I do not insist that this is proper fix. It was just needed to boot the
 device with custom kernel.
 
 Anyway, thanks for comments!
 
Hi Krzysztof and Chanwoo,

So, we don’t need this to fix the problem Krzysztof said? OK.

[PATCH v2 0/6] exynos: Move pmu driver to driver/soc folder and add exynos7 support

2014-11-08 Thread Amit Daniel Kachhap 
This patch series[1 - 6] performs,

1) Moves pmu driver to driver/soc/samsung folder. Some discussion happened about
   this in the v1 version. Finally adding it in driver/soc folder as it too SoC
   specific and not a general driver. Entire discussion can be found here (A).
2) Registers this driver as MFD client driver. This will be used by clients 
like exynos pm
   sleep and pm domain driver.
3) Add exynos7 PMU support.

Changes from V1:
* Move pmu driver in driver/soc/samsung folder
* Removed the power domain features. They will posted as a separate series.
* Added exynos7 PMU support.
* Link to v1 can be found here (B)

This patch has dependency on following patches posted earlier by Pankaj (C),
which is accepted by maintainer.

Patch 6 was earlier posted by Abhilash (D) which has been reposted here with 
some
extra changes.

This complete patch series is rebased on linux-next.

[PATCH v2 5/6] driver: soc: exynos-pmu: Add an API to be called after wakeup

2014-11-08 Thread Amit Daniel Kachhap 
This patch adds an API exynos_sys_powerup_conf to be called
after system sleep wakeup. This is similar to currently existing API
exynos_sys_powerdown_conf.

[PATCH v2 2/6] drivers: soc: Add support for Exynos PMU driver

2014-11-08 Thread Amit Daniel Kachhap 
This patch moves Exynos PMU driver implementation from arm/mach-exynos
to drivers/soc/samsung. This driver is mainly used for setting misc bits of
register from PMU IP of Exynos SoC which will be required to configure
before Suspend/Resume. Currently all these settings are done in
arch/arm/mach-exynos/pmu.c but moving ahead for ARM64 based SoC
support,there is a need of DT based implementation of PMU driver.

This driver uses already existing DT binding information.

[PATCH v2 4/6] soc: samsung: exynos-pmu: Register exynos-pmu driver as a mfd driver

2014-11-08 Thread Amit Daniel Kachhap 
This can be used later to probe and configure PMU client drivers
like pm domain, pm sleep etc. A global structure pmu_dev_client_data is
created to pass exynos-pmu platform data to all the clients. Currently
the data passed is register base addresses.
Although the exynos-pmu driver also provides the sysreg interfaces to
provide register base addresses but this is costlier than readl/writel,
so both the interfaces are provided to mfd based exynos-pmu client
drivers.

 Hi,
 
   I'm sending new pull-request for tags/samsung-pm-v2 instead of

   pull.
  
   Thanks,

  Kukjin,
  
  The history here is somewhat odd. You've merged in cleanup and dt,
  and two merges of pm (one with just the extra fix from Arnd). Are the
  merges needed just to avoid merge conflicts? If so, we can resolve that
  when we merge here, that's not a problem.
  
 Oops, probably I did 'checkout for-next' in my tree when I tagged
 tags/samsung-pm-v2 :(
 
  If it's needed because pm doesn't work without the dt branch also being
  merged in, then this is not sufficient since when bisecting, you might get
  only the pm branch contents and not the dt contents in some circumstances.
  
  So, please confirm which of the cases it is, and resubmit just the bare
  pm branch if there are no dependencies.
  
 Can you please merge branch v3.19-next/pm-samsung-2 instead?
 If you don't want to merge just branch, I'll re-send with new tag.
 
 Sorry for the inconvenience.

Hi,

I've merged the branch into next/soc now.

 Well, as you know the number of uart ports are different on each Samsung 
 SoCs
 so I don't think just using maximum number of uart ports are possible for 
 new
 exynos7 SoC at this moment.

 Thanks for the review.
 The main reason for me sending this patch was so that we may be able
 to re-use the serial driver on arm64 based Exynos7 too. The two
 symbols mentioned above which depend on PLAT_SAMSUNG prevent this. I
 initially sent a patch which changed the dependency to SERIAL_SAMSUNG
 for these 2 symbols. However, Tomasz suggested that a clean-up of
 these two symbols would be a better option.

 Please see the discussion of the previous version here:
 https://lkml.org/lkml/2014/9/29/702

 Can you please let me know if the previous version is acceptable ?

 Kukjin, can you please indicate the approach you would like me to
 take. Without this serial support is blocked on Exynos7.

 Gentle reminder on this.

Hi Kukjin,

I don't mean to nag, but this another reminder to review this.
Please let me know if you are too busy to have a look at this or
require some more inputs from me.

 UART ports possible. Removal of these symbols also helps in Exynos7
 serial enablement.

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

2014-11-08 Thread Abhilash Kesavan 
From: Pankaj Dubey pankaj.du...@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.

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

2014-11-08 Thread 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.

  Hi,
 
  Sorry for late response.

  Well, as you know the number of uart ports are different on each Samsung 
  SoCs
  so I don't think just using maximum number of uart ports are possible 
  for new
  exynos7 SoC at this moment.
 
  Thanks for the review.
  The main reason for me sending this patch was so that we may be able
  to re-use the serial driver on arm64 based Exynos7 too. The two
  symbols mentioned above which depend on PLAT_SAMSUNG prevent this. I
  initially sent a patch which changed the dependency to SERIAL_SAMSUNG
  for these 2 symbols. However, Tomasz suggested that a clean-up of
  these two symbols would be a better option.
 
  Please see the discussion of the previous version here:
  https://lkml.org/lkml/2014/9/29/702
 
  Can you please let me know if the previous version is acceptable ?
 
  Kukjin, can you please indicate the approach you would like me to
  take. Without this serial support is blocked on Exynos7.
 
  Gentle reminder on this.
 
 Hi Kukjin,
 
Hi Abhilash,

 I don't mean to nag, but this another reminder to review this.

Yeah, it's no problem for me ;)

 Please let me know if you are too busy to have a look at this or
 require some more inputs from me.
 
Since I'm still having some objection on 2nd version, how about keeping current
config options for serial for now and changing the dependency to SERIAL_SAMSUNG?
And if required later, we can look into removal these config options later.

Thanks,
Kukjin

please pull.
   
Thanks,

   Kukjin,
  
   The history here is somewhat odd. You've merged in cleanup and dt,
   and two merges of pm (one with just the extra fix from Arnd). Are the
   merges needed just to avoid merge conflicts? If so, we can resolve that
   when we merge here, that's not a problem.
  
  Oops, probably I did 'checkout for-next' in my tree when I tagged
  tags/samsung-pm-v2 :(
 
   If it's needed because pm doesn't work without the dt branch also being
   merged in, then this is not sufficient since when bisecting, you might get
   only the pm branch contents and not the dt contents in some circumstances.
  
   So, please confirm which of the cases it is, and resubmit just the bare
   pm branch if there are no dependencies.
  
  Can you please merge branch v3.19-next/pm-samsung-2 instead?
  If you don't want to merge just branch, I'll re-send with new tag.
 
  Sorry for the inconvenience.
 
 Hi,
 
 I've merged the branch into next/soc now.
 
Thank you so much :)
