a=openpgp; fpr=BFD10BB334A55FBD4365340915958A5E111C05DE The v8 phy-qcom-mipi-csi2 binding mandates power-domain-names ordered "mmcx", "mx" (MMCX first), and its driver reads each domain's required performance state by index via dev_pm_opp_get_required_pstate(opp, i). The v3-era camss DTSI listed them "mx", "mmcx" (MXC/MX first), which is rejected by the v8 binding and, with the v8 driver's devm_pm_domain_attach_list() + per-index OPP lookup, maps the wrong pstate to the wrong rail. Reorder all four csiphy nodes to , / "mmcx", "mx". The second rail stays MXC for csiphy0/1/2 and MX for csiphy4 (the binding explicitly allows "MXC or MXA" for the second domain); the opp-table required-opps values are symmetric so they need no change.
