SA8775P is a Qualcomm SoC. This series adds driver changes to bring up the TPG interfaces in SA8775P. We have tested this on qcs9100-ride board with 'Test Pattern Generator'. Unlike CSID TPG, this TPG can be seen as a combination of CSIPHY and sensor.

Great to see this work. I think the TPG should be another type of PHY. --- bod
