+  The Amlogic Meson Synopsys Designware Integration is composed of
+  - A Synopsys DesignWare HDMI Controller IP
+  - A TOP control block controlling the Clocks and PHY
+  - A custom HDMI PHY in order to convert video to TMDS signal

+
+  The HDMI TOP block only supports HPD sensing.
+  The Synopsys HDMI Controller interrupt is routed through the
+  TOP Block interrupt.
+  Communication to the TOP Block and the Synopsys HDMI Controller is done
+  via a pair of dedicated addr+read/write registers.
+  The HDMI PHY is configured by registers in the HHI register block.
+
+  Pixel data arrives in "4:4:4" format from the VENC block and the VPU HDMI mux
+  selects either the ENCI encoder for the 576i or 480i formats or the ENCP
+  encoder for all the other formats including interlaced HD formats.
+
+  The VENC uses a DVI encoder on top of the ENCI or ENCP encoders to generate
+  DVI timings for the HDMI controller.
+
+  Amlogic Meson GXBB, GXL and GXM SoCs families embeds the Synopsys DesignWare
+  HDMI TX IP version 2.01a with HDCP and I2C & S/PDIF
+  audio source interfaces.
