The driver itself does not depend on the DTS. Apologies for the confusion. The Depends-on was included purely for testing purposes. During validation on sa8775p, qcs8300, and sc7280, we needed the corresponding DTSI changes to instantiate the C-PHY consumer nodes so the driver could probe and be exercised on real hardware. Without those device-tree nodes, the driver simply wouldn't bind on those platforms in our test environments. Since this is a C-PHY consumer driver, the DTS patches are what enable the PHY nodes that the driver attaches to. They are a prerequisite for functional testing, not for compilation or correctness of the driver code itself. The driver is self-contained and will build and function correctly independent of those DTS changes. I will drop the Depends-on from the next revision. Apologies for the noise.
