From: Bartosz Golaszewski <brgl@kernel.org> Extend the driver to support a new model - sa8255p. Unlike the previously supported variants, this one's power management is done in the firmware using SCMI. This is modeled in linux using power domains so add support for them.quoted
static const struct of_device_id qcom_ethqos_match[] = { { .compatible = "qcom,qcs404-ethqos", .data = &emac_qcs404_data}, + { .compatible = "qcom,sa8255p-ethqos", .data = &emac_sa8255p_data},Is this device being probed via DT or ACPI?
On the sa8255p it's probed via DT but all its resources are managed in firmware over SCMI. Bartosz
