+Drivers for the second video output of the GE B850v3:
|
|
|
+ STDP4028-ge-b850v3-fw bridges (LVDS-DP)
|
|
|
+ STDP2690-ge-b850v3-fw bridges (DP-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 specific for the GE B850v3.
|
|
|
+
|
|
|
+The hardware do not provide control over the video processing pipeline, as the
|
|
|
+two bridges behaves as a single one. The only interfaces exposed by the
|
|
|
+hardware are EDID, HPD, and interrupts.

+stdp4028-ge-b850v3-fw required properties:
|
|
|
+ - compatible : "megachips,stdp4028-ge-b850v3-fw"
|
|
|
+ - reg : I2C bus address
|
|
|
+ - interrupt-parent : phandle of the interrupt controller that services
|
|
|
+ interrupts to the device
|
|
|
+ - interrupts : one interrupt should be described here, as in
|
|
|
+ <0 IRQ_TYPE_LEVEL_HIGH>
|
|
|
+ - ports : One input port(reg = <0>) and one output port(reg = <1>)
