drm/mediatek: fix mtk_hdmi_setup_vendor_specific_infoframe mistake

2017-06-24T05:06:16+00:00

commit 014580ffab654bb83256783a2b185cf6c06dffaa upstream. mtk_hdmi_setup_vendor_specific_infoframe will return before handle mtk_hdmi_hw_send_info_frame.Because hdmi_vendor_infoframe_pack returns the number of bytes packed into the binary buffer or a negative error code on failure. So correct it. Fixes: 8f83f26891e1 ("drm/mediatek: Add HDMI support") Signed-off-by: Nickey Yang Signed-off-by: CK Hu Signed-off-by: Greg Kroah-Hartman

drm: mediatek: use crtc helper drm_crtc_from_index()

2017-01-18T14:21:06+00:00

Use drm_crtc_from_index() to find drm_crtc for given index, so that we do not need to maintain a pointer array in struct mtk_drm_private.

drm: bridge: Link encoder and bridge in core code

2016-12-18T11:01:45+00:00

Instead of linking encoders and bridges in every driver (and getting it wrong half of the time, as many drivers forget to set the drm_bridge encoder pointer), do so in core code. The drm_bridge_attach() function needs the encoder and optional previous bridge to perform that task, update all the callers.

drm/mediatek: don't use drm_put_dev

fsl is already fully demidlayered in the probe function, but for convenience stuck with drm_put_dev. Call the unregister/unref parts separately, to make sure this driver works correct.

drm: Make the connector .detect() callback optional

2016-12-01T15:05:53+00:00

Many drivers (21 to be exact) create connectors that are always connected (for instance to an LVDS or DSI panel). Instead of forcing them to implement a dummy .detect() handler, make the callback optional and consider the connector as always connected in that case.
