Hello,

Please post the documentation for the bindings.

Thanks,
Leela Krishna Amudala.

 This patch enables device tree based discovery support for DP driver.
 The driver is modified to handle platform data in both the cases:
 with DT and non-DT.

 DP-PHY should be regarded as a seperate device node while
 being passed from device tree list, and device node for
 DP should contain DP-PHY as child node with property name dp-phy
 associated with it.

[PATCH 0/3] Add device tree based discovery support for drm-fimd

2012-09-18 Thread Leela Krishna Amudala
This patch set adds arch side support for device tree based discovery
for drm-fimd.

The patches are created against for-next branch of Kukjin Kim's tree on 
3.6-rc6 at:
 git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung.git

This patchset has been tested on smdk5250 board and seen the bootup logo on LCD
using the patchset http://www.spinics.net/lists/arm-kernel/msg193348.html which 
was 
applied on inki-dae's next branch

[GIT PULL] Samsung fixes-3 for v3.6

2012-09-18 Thread Kukjin Kim

Hi Arnd, Olof

This is re-sending Samsung fixes-3 I talked to Olof before.

The branch is including two commits are using spin_lock_{irqsave, 
irqrestore} in clk_set_parent() and clk_set_rate() to avoid spinlock 
recursion/locking.


If any problems, please kindly let me know.

Thanks.

Best regards,
Kgene.
