Implement the .set_crc_source() callback and call the DP helpers accordingly to start and stop CRC capture. This is only done if this CRTC is currently using the eDP connector. v3: Remove superfluous check on rockchip_crtc_state->output_type v6: Remove superfluous variable Signed-off-by: Tomeu Vizoso <tomeu.vizoso@collabora.com> --- drivers/gpu/drm/rockchip/rockchip_drm_vop.c | 41 +++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+)
