Remove the dependency on drm_simple_kms_helper by open-coding the
drm_simple_encoder_init call.

this description is missing a rationale.

Looking at the drm git history, I guess here you could add a second
paragraph, with something like:

----------- 8< -----------
The helpers have been deprecated for years as they only add an an
intermediate layer between atomic modesetting and the DRM driver.
----------- 8< -----------

Shamelessly stolen from the Todo item ;-)

Any reason for only changing the DSI driver?

Looking at [0] a number of the Rockchip drivers use the same pattern:
- drivers/gpu/drm/rockchip/analogix_dp-rockchip.c
- drivers/gpu/drm/rockchip/cdn-dp-core.c
- drivers/gpu/drm/rockchip/dw-mipi-dsi-rockchip.c
- drivers/gpu/drm/rockchip/dw-mipi-dsi2-rockchip.c
- drivers/gpu/drm/rockchip/dw_hdmi-rockchip.c
- drivers/gpu/drm/rockchip/dw_hdmi_qp-rockchip.c
- drivers/gpu/drm/rockchip/rk3066_hdmi.c
- drivers/gpu/drm/rockchip/rockchip_lvds.c
- drivers/gpu/drm/rockchip/rockchip_rgb.c

You can just do all Rockchip ones - even in one patch I think :-) .


Thanks
Heiko

True. I will add the rationale then.

Yes, indeed. I wanted to send a tiny patch to check if all my
configurations were ok, but since it looks like they are, I will add the
other rockchip drivers that have the deprecated functions.

Thanks,
Diogo

sorry for mangling your name, Diogo.


Heiko

Simple KMS helper are deprecated since they only add an intermediate
layer between drivers and the atomic modesetting.
This patch removes the dependency on drm_simple_encoder_init from rockchip
DRM drivers by inlining this helper.
