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 ;)

Beyond that, there are 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).

I have verified this series on two kinds of rockchip platform board, one
is rk3288 sdk board which connect with a 2K display port monitor, the other
is google jerry chromebook which connect with a eDP screen "cnm,n116bgeea2",
both of them works rightlly.

I haven't verified the dp function on samsung platform, cause I haven't got
exynos boards. I can only ensure that there are no build error on samsung
platform, wish some samsung guys help to test. ;)
I'd like to pull this in, but it probably needs an ack from Samsung,

Inki can you guys find some time to test this?

Dave.

Wow, thanks a lots :-)

Still waiting for some reviews and acks.

Best regards,
- Yakir
