DS90UB953-Q1: Issue with TPG generation

Part Number: DS90UB953-Q1
Other Parts Discussed in Thread: DS90UB951-Q1, DS90UB958-Q1

Hi,

Firstly, my actual part number is DS90UB951-Q1 which is not in the list. Hence using the nearest cousin. Apologies for that.

I am trying to generate a Test pattern from Serializer with the following configuraitons

- 3848x2168 (4K) resolution @ 30fps

- RAW12 data type.

I have attached the register configuration that I am currently using (The CSI Enable will be set at a later point in code)

	reg_data = 0x11;
	reg_addr = 0xB2;
	reg_data = 0xFF;

	reg_addr = 0xB1;
	reg_data = 0x12;
	reg_addr = 0xB2;
	reg_data = 0xF8;

The same configuration works for deserializer as shown in the below image (Ignore the color as it is done by incorrect post processing)

However, When I apply the same register configurations for Serializer, I get something completely different. It looks like below images

When I dumped the Registers from (0x4C - 0x7F) of my DS90UB958-Q1 deserializer during streaming, I see that there are a lot of errors on the Channel. Attached the logs for reference
