On SM8750, CSIPHY blocks are standalone PHY devices rather than legacy sub-resources inside the CAMSS node, so camss_detect_legacy_phy() sets camss->legacy_phy =3D false and camss_parse_ports() sets lane_base =3D 1. camss_parse_endpoint_node() then rejects lane 0 with -EINVAL and fails probe: drivers/media/platform/qcom/camss/camss.c:camss_parse_endpoint_node() { ... if (lane < lane_base || lane - lane_base >=3D MSM_CSIPHY_MAX_DATA_LANE) { dev_err(dev, "invalid data-lane %u\n", lane); return -EINVAL; } ... } The endpoint schema for data-lanes could also constrain items to minimum: 1 and maximum: 4 so 0-based lane indices are caught by schema validation. --=20 Sashiko AI review =C2=B7 https://sashiko.dev/#/patchset/20261114-add-suppor= t-for-camss-on-sm8750-v7-0-8ff2a11835f6@oss.qualcomm.com?part=3D3
