This series extends the generic Qualcomm MIPI CSI2 PHY driver
(drivers/phy/qualcomm/phy-qcom-mipi-csi2-*) with three additional
CSIPHY variants: SA8775P, QCS8300 and SC7280. The driver currently
only supports x1e80100; these SoCs let CAMSS consume the CSIPHY through
the common PHY framework instead of the CSIPHY logic embedded in the
legacy in-tree CAMSS driver.
QCS8300 shares the same CSIPHY D-PHY hardware as SA8775P, so it does
not need its own of_device_id entry: the qcom,csi2-phy.yaml binding
declares "qcom,sa8775p-csi2-phy" as QCS8300's fallback compatible, and
QCS8300 CSIPHY nodes bind through patch 4's existing
"qcom,sa8775p-csi2-phy" match entry.
Tested on sa8775p, qcs8300 and sc7280.

SA8775P, QCS8300 and SC7280 CSI2 PHYs are bit-for-bit identical in
devicetree shape (ports, bus-type, data-lanes, operating-points-v2,
clocks, single "top" power-domain, vdda-phy/vdda-pll supplies).
Describe all three with a single qcom,csi2-phy.yaml and a compatible
oneOf, rather than one standalone schema per SoC. QCS8300 is further
required to be paired with a qcom,sa8775p-csi2-phy fallback
compatible, the same way other Qualcomm bindings express full
hardware compatibility between two SoCs (see qcom,qusb2-phy.yaml);
this lets the driver bind QCS8300 nodes via its qcom,sa8775p-csi2-phy
match entry rather than carrying a duplicate one.
qcom,x1e80100-csi2-phy.yaml is a separate PHY with a different shape
(3 clocks, 3 power-domains, different supply names, DPHY split-mode
support) and is left untouched.

The timer-clock lookup in phy_qcom_mipi_csi2_probe() and the OPP
clkname passed to devm_pm_opp_set_clkname() were both hardcoded
string literals sized to x1e80100 ("timer"/"core"). Add
timer_clk_name/opp_clk_name to struct mipi_csi2phy_soc_cfg so each
SoC can declare its own clock-name strings instead.
x1e80100's soc_cfg now declares "timer"/"core" explicitly; no
behaviour change.

Not every SoC the generic MIPI CSI2 PHY driver supports needs an OPP
table: a CSIPHY with only a single, unscaled power-domain has no
performance state to vote on, so running its "core" clock through
the OPP framework buys nothing over a plain clk_set_rate(). Skip
devm_pm_opp_set_clkname()/devm_pm_opp_of_add_table() in probe() and
the OPP/performance-state handling in
phy_qcom_mipi_csi2_set_clock_rates() when soc_cfg->opp_clk_name is
unset, falling back to clk_round_rate()/clk_set_rate() on the timer
clock only.
x1e80100 still sets opp_clk_name, so this is a no-op for it.

Add the SA8775P CSIPHY to the generic MIPI CSI2 PHY driver,
bound to a new "qcom,sa8775p-csi2-phy" compatible
and reusing the existing D-PHY 2-phase hw ops
(phy_qcom_mipi_csi2_ops_3ph_1_0). The lane_regs_sa8775p[] init
sequence is the CSIPHY v1.3.0 2-phase 2.5Gbps 4-lane D-PHY register
set ported verbatim from the legacy in-tree camss-csiphy-3ph-1-0.c
table; common_regs_offset is 0x800.
SA8775P reuses the same "timer"/"core" clock names as x1e80100
(timer_clk_name/opp_clk_name added by a preceding patch). Like
x1e80100, its CSIPHY core clock is OPP-scaled against the sensor's
link frequency via the shared csiphy_opp_table in lemans.dtsi,
matching the legacy in-tree CSIPHY driver's own sa8775p_resources
OPP wiring.
SA8775P's CSIPHY has a single power-domain, the Titan Top GDSC,
matching the legacy in-tree CAMSS driver's sa8775p_resources.pd_name
= "top" and the existing lemans.dtsi camss node. Like x1e80100's own
"top" domain, it is not OPP-scaled, only kept enabled.
QCS8300 shares this same CSIPHY D-PHY hardware and does not need its
own of_device_id entry: the qcom,csi2-phy.yaml binding declares
"qcom,sa8775p-csi2-phy" as QCS8300's fallback compatible, so QCS8300
CSIPHY nodes bind through the "qcom,sa8775p-csi2-phy" match entry
added here.

Add the SC7280 CSIPHY to the generic MIPI CSI2 PHY driver,
bound to a new "qcom,sc7280-csi2-phy" compatible
and reusing the existing D-PHY 2-phase hw ops
(phy_qcom_mipi_csi2_ops_3ph_1_0). The lane_regs_sc7280[] init
sequence is the CSIPHY 5nm 2-phase 2.5Gbps 4-lane D-PHY register
set ported from the legacy in-tree camss-csiphy-3ph-1-0.c table,
with the entries that table left as do-not-program placeholders
simply omitted here rather than carried as a new marker. The
soc_cfg declares the core/timer clocks (matching x1e80100's and
sa8775p's clock-names convention for this pair) and the
vdda-phy/vdda-pll supplies.
Like x1e80100 and SA8775P, SC7280's CSIPHY core clock is OPP-scaled
against the sensor's link frequency via the shared csiphy_opp_table
in kodiak.dtsi, so opp_clk_name is set to "core" here too. SC7280's
CSIPHY has a single power-domain, the Titan Top GDSC, matching
camss.c's sc7280_resources.pd_name = "top" and kodiak.dtsi's
existing camss node; it is not OPP-scaled, only kept enabled.
