[PATCH WIP v4 7/9] media: qcom: camss: csiphy-3ph: Add Gen2 v1.2.1 MIPI CSI-2 C-PHY init
Posted by David Heidelberg via B4 Relay 1 month, 1 week ago 
From: Luca Weiss <luca.weiss@fairphone.com>

Add a PHY configuration sequence for the sm8250 which uses a Qualcomm
Gen 2 version 1.2.1 CSI-2 PHY.

The PHY can be configured as two phase or three phase in C-PHY or D-PHY
mode. This configuration supports three-phase C-PHY mode.
