Hi all,
Friendly ping..... :)
Best regards,

Do you have a tree that I can use to test these patches?
Wow, thanks a lot, I do have a tree on github [https://github.com/yakir-Yang/linux/tree/analogix_dp],
crossing my finger, wish things works...... ;)
I tried your analogix_dp branch on an Exynos5800 Peach Pi Chromebook
but the machine didn't boot. Unfortunately I need to do some soldering
to have a serial console on this board so don't have a kernel boot log.
I'll let you know if I can get more info about this issue.
Whoops, sorry for the failed, much appreciated for your works.
Besides, I thought maybe I can find a Peach Pit Chromebook in my side,
I remember that some of our guys have brought one, but previously I
thought that mainline kernel wouldn't run on Peach Pit directly.
Great, mainline works correctly on all Exynos based Chromebooks.
Maybe you can email me the method the run mainline kernel on Peach
Pit, so I can debug the analogix_dp driver at the same time, that would
be great.
I wrote a little blog post explaining how to run mainline on these boards:
http://blogs.s-osg.org/install-linux-mainline-kernel-distro-exynos-chromebooks/
That explains the simplest setup though so if you need a different one
(i.e: chain loading a non verified u-boot) or if you have any questions,
feel free to contact me in private and I can help you with the setup.
Ah, thanks, gonna to step-by-step.

Also, there is Kconfig recursive dependency that you may want to fix:
$ make exynos_defconfig
drivers/video/fbdev/Kconfig:5:error: recursive dependency detected!
drivers/video/fbdev/Kconfig:5: symbol FB is selected by DRM_KMS_FB_HELPER
drivers/gpu/drm/Kconfig:34: symbol DRM_KMS_FB_HELPER depends on DRM_KMS_HELPER
drivers/gpu/drm/Kconfig:28: symbol DRM_KMS_HELPER is selected by DRM_ANALOGIX_DP
drivers/gpu/drm/bridge/analogix/Kconfig:1: symbol DRM_ANALOGIX_DP is selected by DRM_EXYNOS_DP
drivers/gpu/drm/exynos/Kconfig:57: symbol DRM_EXYNOS_DP depends on DRM_EXYNOS_FIMD
drivers/gpu/drm/exynos/Kconfig:19: symbol DRM_EXYNOS_FIMD depends on FB_S3C
drivers/video/fbdev/Kconfig:2023: symbol FB_S3C depends on FB
Yeah, recursive dependency detected, guess I should remove the
"DRM_KMS_HELPER" from bridge analogix_dp Kconfig file, thanks
for your remind.

That fixes the recursive dependency issue indeed. Thanks.
