HD3SS215: Would like a schematic review for my HD3SS215 circuit

For the HD3SS215, I need TI to review this page of the schematic.  The questions I have are is the HDMI_CEC_SNK, HPD_SRC, HPD_HDMI_CON_OUT, HDMI_5V_CON, and the HDMI_DDC_SCL/SDA signals hooked up right.

    1. Please make sure having decoupling caps on 3.3V supply.

    2. GND connection missing GND symbol

    3. AUX_SEL and DX_SEL are physically tied to high and low, how do they plan to switch between the two HDMI sinks?

    4. CEC does not go through HD3SS215. You just need to connect them together and then connect to the source.

    5 HPD can go through HD3SS215, but you don't want to tie the HPD from the two sinks together

    Please take a look at HD3SS215 EVM for reference.

    Thanks
