We used to call drm_of_encoder_active_endpoint_id() from
rockchip_dp_drm_encoder_atomic_check() to determine the endpoint for the
active encoder. However, the encoder isn't necessarily active at this
point or it may be connected to different crtc than what we're switching
to. Instead, look at the crtc from the drm_crtc_state. This fixes wrong
colors when driving the eDP with the big VOP. Further, we can identify
the type of VOP we're dealing with by just putting a VOP id enum in the
vop_data.
On way to test this is to use the modetest tool from libdrm:
$ modetest -M rockchip -s 32@28:2400x1600
which displays dark or black colors because we fail to look up the
endpoint and use default 0 (which is ROCKCHIP_OUT_MODE_P888) for big
VOP instead of RGB10 as required.
For reference,
$ modetest -M rockchip -s 32@25:2400x1600
drives the eDP from little VOP and displays correctly.

Missing EXPORT() causes build errors if calling code is built as module.
Example arm64:allmodconfig:
ERROR: "vop_get_crtc_vop_id" [drivers/gpu/drm/rockchip/dw-mipi-dsi.ko] undefined!
ERROR: "vop_get_crtc_vop_id" [drivers/gpu/drm/rockchip/cdn-dp.ko] undefined!
ERROR: "vop_get_crtc_vop_id" [drivers/gpu/drm/rockchip/analogix_dp-rockchip.ko] undefined!

Do you plan to fix the errors Guenter pointed out and resend? This is
still causing conflicts between our ChromeOS kernel trees and upstream.
Also, please CC linux-rockchip on Rockchip-related patches. It's much
easier for me to find your work that way :)

Unfortunately, vop iomux and vop data are not one-to-one correspondence.
Such as rk3288, vop big and vop little both use rk3288_vop data, if you use vop data id will not be able
to distinguish between them.

What would you suggest then? We need this to be able to drive eDP from
the big VOP. We've been carrying this patch for quite a while and it
hasn't regressed neither rk3288 nor rk3399 boards.

The display issue already be fixed, and your kernel seems old
See the patch: http://patchwork.freedesktop.org/patch/msgid/1495885416-22216-1-git-send-email-mark.yao@rock-chips.com
Now eDP always set its outmode as ROCKCHIP_OUT_MODE_AAAA.
And on vop driver, force RGB10 to RGB888 if vop not support rgb10bit.
drivers/gpu/drm/rockchip/rockchip_drm_vop.c:
/*
* if vop is not support RGB10 output, need force RGB10 to RGB888.
*/
if (s->output_mode == ROCKCHIP_OUT_MODE_AAAA &&
!(vop_data->feature & VOP_FEATURE_OUTPUT_RGB10))
s->output_mode = ROCKCHIP_OUT_MODE_P888;
Thanks.
