I'm a bit confused here. drm_encoder_init() exist here and in
mtk_dsi_create_conn_enc(). Do you plan to init encodr twice?

There is mtk_dsi_encoder_init() in bind(), why no mtk_dsi_encoder_uninit() here?

Right, it should be removed from mtk_dsi_create_conn_enc(). I will do in next

Right, I need uninit the encoder but a simple call to drm_encoder_cleanup should
be enough. I don't think is needed create a new function for that. I'll do in
next version.
