[PATCH 0/2] media: qcom: camss: track PHY type and scale link frequency for C-PHY

[Anusha Arun Nandi]

This series lays the CAMSS-side groundwork for MIPI C-PHY sensors.

Patch 1 records whether a CSIPHY endpoint is D-PHY or C-PHY from its
device-tree bus-type property (instead of rejecting anything that
isn't D-PHY), storing it in struct csiphy_lanes_cfg.

Patch 2 threads that PHY type through to link-frequency calculation:
camss_get_link_freq() gains a cphy parameter and scales its per-lane
divisor to match C-PHY's 16-bits-per-7-symbols encoding (vs. D-PHY's
1 bit/symbol), and the CSID gen3 RX front-end's CSI2_RX_CFG0 register
is programmed with the matching PHY_TYPE_SEL bit so C-PHY streams are
actually decoded as C-PHY instead of silently defaulting to D-PHY.
