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

This series have been well tested on Rockchip platform with eDP panel on
Jerry Chromebook and Display Port Monitor on RK3288 board. Also I have
tested on Samsung Snow and Peach Pit Chromebooks, and thanks to Javier@Samsung
help to retest the whole series on Samsung Exynos5800 Peach Pi Chromebook,
glad to say that things works rightlly.
Patch 15/17 looks like it didn't make it? I haven't found it in neither my
inbox nor in the linux-rockchip list archive? So I've used the v7 version
for my tests.

Oops, thanks for your reminding, I would send it now.

This series on a rk3288-veyron-pinky and rk3288-veyron-jerry
