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
could you rebase your patches on top of Dave's drm-next branch [0] please? The exynos part got some const attributes for the *_func_ops structs and drm_encoder_init got an additional parameter. I'm still hoping that we can get this finally committed once 4.5-rc1 is released in 1.5 weeks :-) .
I did try to merge things together [1], the system at least comes up and detects the panel (EDID is read correctly and it turns the backlight on) but I don't see any output on the display - hdmi works fine though and X11 is claiming everything to be fine in both cases.
So I don't know yet if I made a mistake when putting this together or there is an issue on the driver-side.
I was able to debug this a bit more, and it seems the encoder_helper_funcs don't like the prepare/commit callbacks and like enable better.
So when I do something similar to Marks patch a8eef71d38da ("drm/rockchip: dw_hdmi: use encoder enable function"), like in the attached patch (to be folded into the original addition of those functions), I get display output again.
