ANX78XX is an ultra-low Full-HD SlimPort transmitter
designed for portable devices. The ANX78XX transforms
the HDMI output of an application processor to MyDP
or DisplayPort.

drm/bridge: Drivers for megachips-stdpxxxx-ge-b850v3-fw (LVDS-DP++) The video processing pipeline on the second output on the GE B850v3: Host -> LVDS|--(STDP4028)--|DP -> DP|--(STDP2690)--|DP++ -> Video output Each bridge has a dedicated flash containing firmware for supporting the custom design. The result is that in this design neither the STDP4028 nor the STDP2690 behave as the stock bridges would. The compatible strings include the suffix "-ge-b850v3-fw" to make it clear that the driver is for the bridges with the firmware which is specific for the GE B850v3. The driver is powerless to control the video processing pipeline, as the two bridges behaves as a single one. The driver is only needed for telling the host about EDID / HPD, and for giving the host powers to ack interrupts. This driver adds one i2c_device for each bridge, but only one drm_bridge. This design allows the creation of a functional connector that is capable of reading EDID from the STDP2690 while handling interrupts on the STDP4028.
