Hi all,
Samsung exynos and Rockchip rk3288 almost share same dp controller,
so I split the common code out, then rk3288 and exynos can re-used the
same dp core driver. 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 ;)

OK, I see.
The Samsung Exynos eDP contoller and Rockchip rk3288 eDP contoller share
the same IP. So, a lot of parts can be re-used. I agree with this.
However, we have to review the code carefully, as others did.
Yeah, feel happy to be reviewed ;)

I also cannot find the exact IP name. The "analogix" may be the vendor name
of this IP.
Okay, so "analogix" is okay for now

Thanks,

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).

My series patches can be divider into two parts: One for spliting the
analogix_dp code from exynos dp driver. Another are trying to add rk3288
dp driver support.

Best regards,
