Hi all,
The Samsung Exynos eDP controller and Rockchip RK3288 eDP controller
share the same IP, so a lot of parts can be re-used. I split the common
code into bridge directory, then rk3288 and exynos only need to keep
some platform code. Cause I can't find the exact IP name of exynos dp
controller, so I decide to name dp core driver with "analogix" which I
find in rk3288 eDP TRM :)
But there are still three light registers setting differents bewteen
exynos and rk3288.
1. RK3288 have five special pll resigters which not indicata in exynos
dp controller.
2. The address of DP_PHY_PD(dp phy power manager register) are different
between rk3288 and exynos.
3. Rk3288 and exynos have different setting with AUX_HW_RETRY_CTL(dp debug
register).
This series have been well tested on Rockchip platform with eDP panel
on Jerry Chromebook and Display Port Monitor on RK3288 board and thanks
to Javier@Samsung help me to find a way to install mainline kernel to
Samsung Exynos Chromebooks, so this series also have been tested on Samsung
Snow and Peach Pit Chromebooks which borrowed from my friends.
Besides, This version was build on linux-next branch (tag next-20150918), and
the above test experiments also base on that tag. But I know the latest tag is
next-20151009, so i do rebase this series again on next-20151009, there were
little conflicts(exynos_dp removed the suspend/resume).
But after I retest this series on next-20151009, I saw kernel crashed in mmc
driver(dw_mci_probe failed to get regulator). So i have to disabled the MMC
module(after all I boot with USB device), and I can see eDP light up normally
in startup stage, but kernel keep crashed when it try to mount the filesystem.
I thought this isn't related to dp driver directly, so i choice not to debug
more depth.
That's to say if someone want to test this series, I suggest you applied this
series on tag-20150918, just need to fix some light conflicts with the 01 & 02
patches (or just email me, I can send you directly).
Thanks,
Do you have a branch that I can use to test this series?
Thank you for your kind assistance, I have created a tree which checkout from the next-20151019. Surely there were some conflicts to applied this series on that tag, but things still works for me, here is the git address [https://github.com/yakir-Yang/linux/tree/analogix_dp]
I tested your branch on an Exynos5800 Peach Pi Chromebook and display is
working on boot. I also tested DPMS and S2R and things are still working
so for the whole series feel free to add:
Tested-by: Javier Martinez Canillas <javier@xxxxxxxxxxxxxxx>
Thanks a lot ;)
