+ * HDMI Output is composed of :
+ * - A Synopsys DesignWare HDMI Controller IP
+ * - A TOP control block controlling the Clocks and PHY
+ * - A custom HDMI PHY in order convert video to TMDS signal
+ *  ___________________________________
+ * |            HDMI TOP               |<= HPD
+ * |___________________________________|
+ * |                  |                |
+ * |  Synopsys HDMI   |   HDMI PHY     |=> TMDS
+ * |    Controller    |________________|
+ * |___________________________________|<=> DDC
+ *
+ * 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 a pair of 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.
+ *
+ * GXBB, GXL and GXM embeds the Synopsys DesignWare
+ * HDMI TX IP version 2.01a with HDCP and I2C & S/PDIF
+ * audio source interfaces.
+ *
+ * We handle the following features :
+ * - HPD Rise & Fall interrupt
+ * - HDMI Controller Interrupt
+ * - HDMI PHY Init for 480i to 1080p60
+ * - VENC & HDMI Clock setup for 480i to 1080p60
+ * - VENC Mode setup for 480i to 1080p60
+ *
+ * What is missing :
+ * - PHY, Clock and Mode setup for 2k && 4k modes
+ * - SDDC Scrambling mode for HDMI 2.0a
+ * - HDCP Setup
+ * - CEC Management
