2016-12-18drm: bridge: Link encoder and bridge in core codeLaurent Pinchart
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.

We get 4 warnings when building kernel with W=1: drivers/gpu/drm/mediatek/mtk_hdmi.c:1089:6: warning: no previous prototype for 'mtk_hdmi_audio_enable' [-Wmissing-prototypes] drivers/gpu/drm/mediatek/mtk_hdmi.c:1095:6: warning: no previous prototype for 'mtk_hdmi_audio_disable' [-Wmissing-prototypes] drivers/gpu/drm/mediatek/mtk_hdmi.c:1101:5: warning: no previous prototype for 'mtk_hdmi_audio_set_param' [-Wmissing-prototypes] drivers/gpu/drm/mediatek/mtk_hdmi.c:1627:5: warning: no previous prototype for 'mtk_hdmi_audio_digital_mute' [-Wmissing-prototypes] In fact, both functions are only used in the file in which they are declared and don't need a declaration, but can be made static. So this patch marks both functions with 'static'.

2016-06-16drm/mediatek: enable hdmi output control bitJie Qiu
MT8173 HDMI hardware has a output control bit to enable/disable HDMI output. Because of security reason, so this bit can ONLY be controlled in ARM supervisor mode. Now the only way to enter ARM supervisor is the ARM trusted firmware. So atf provides a API for HDMI driver to call to setup this HDMI control bit to enable HDMI output in supervisor mode.

2016-06-16drm/mediatek: Add HDMI supportJie Qiu
This patch adds drivers for the HDMI bridge connected to the DPI0 display subsystem function block, for the HDMI DDC block, and for the HDMI PHY to support HDMI output. This includes an interface to the generic hdmi-codec driver to start or stop audio playback and to retrieve ELD (EDID like data) to limit the supported audio formats to the HDMI sink capabilities.
