[PATCH v3 2/3] arm64: dts: qcom: monaco: add CSI2 PHY common-phy providers

From: Anusha Arun Nandi

Date: Thu Nov 05 2026 - 22:04:57 EST


Expose the three QCS8300 CSIPHYs as standalone
qcom,qcs8300-csi2-phy generic-PHY provider nodes (csiphy0..2) at their
existing register addresses, each with its own OF graph (port@0
sensor-facing, port@1 CAMSS-facing) so camss_detect_legacy_phy() picks
the non-legacy path once a board wires a sensor through one of them.
The camss node's own reg-names/clocks/interrupts for the CSIPHYs are
unchanged, so boards that don't use a provider still get the legacy
binding.

csiphy0..2 drop the extra "csiphy_rx" clock: QCS8300 binds through the
sa8775p soc_cfg (no dedicated QCS8300 camcc driver exists), which only
declares two clocks ("core", "timer") for this PHY, not three.

csiphy_opp_table moves to the root node, not inside soc@0 (a
simple-bus), since it has no reg/ranges property of its own; its
opp-300000000 entry is dropped too, since QCS8300 shares SA8775P's
camcc, whose cam_cc_cphy_rx_clk_src only defines a 400 MHz rate.

The provider nodes are disabled by default; a board or camera overlay
enables the one(s) it uses.
