HDMI register documentation

It seems a lot of HDMI registers are not documented properly.

For example linux driver initializes this register that is not mentioned by Technical Reference Manual:

TI814x_HDMI_TXPHY_PAD_CFG_CTRL

Where are these registers documented?

Llandre,

Most of the HDMI registers are only available under NDA due to third party licensing.

In 99.99% of use cases the customer never needs to know about nor touch associated registers.

Is there a specific question you are addressing?

BR,

Steve

Generally speaking, I'd like to have this documentation for debug purposes. For example it seems HDMI PHY registers can provide useful information about link status.

Hi,

We have added HDP interrupt in the latest PSP release. There is a register configuration which allows to get HPD interrupt and then another register can be read to find out the HPD status. You can refer latest code in PSP. Its target release is 15th Feb as of now.

Regards,
