Subject: [PATCH v7 02/15] dt-bindings: media: qcom,x1e80100-camss: Convert
from inline PHY definitions to PHY handles
We currently do not have an upstream user of the x1e CAMSS schema which
allows us to make this the first platform to treat the CSI PHYs as separate
devices in much the same way as we treat the CCI block as separate devices.
Convert the embedded CSIPHY node data to simple phys = <> removing all of
the PHY specific stuff previously embedded.
I gave some serious thought to making the Test Pattern Generators TPGs into
PHY nodes also but, unlike the CSIPHYs the TPGs have no dedicated external
pins nor regulators.
The CSIPHYs OTOH have dedicated in-fact generally unmuxed pins on Qualcomm
SoCs and each CSIPHY has its own set of input power rails usually 0p8 and
1p2.
Instead of defining the CSIPHYs as children of the CAMSS block, we take the
same approach as the CCI/I2C bus dedicated to CAMSS and define the CSIPHYs
as their own nodes.
Remove the embedded CSIPHY specific data and give CAMSS regular,
bog-standard phys = <>;
