+Endpoint node required properties for parallel connection are:
+- remote-endpoint: a phandle to the bus receiver's endpoint node.
+- bus-width: shall be set to <8> for 8 bits parallel bus
+ or <10> for 10 bits parallel bus
+- data-shift: shall be set to <2> for 8 bits parallel bus
+ (lines 9:2 are used) or <0> for 10 bits parallel bus
+- hsync-active: active state of the HSYNC signal, 0/1 for LOW/HIGH respectively.
+ (Not required for bus-type equal 6)
+- vsync-active: active state of the VSYNC signal, 0/1 for LOW/HIGH respectively.
+ (Not required for bus-type equal 6)
+- pclk-sample: sample data on rising (1) or falling (0) edge of the pixel clock
+ signal. (Not required for bus-type equal 6)
+- bus-type: data bus type. Possible values are:
+ 5 - Parallel
+ 6 - Bt.656
+
