From: "Tan, Tee Min" <redacted> Intel platform will configure the SerDes through PMC api based on the provided interface mode. This patch adds several new functions below:- - intel_tsn_interface_is_available(): This new function reads FIA lane ownership registers and common lane registers through IPC commands to know which lane the mGbE port is assigned to. - intel_config_serdes(): To configure the SerDes based on the assigned lane and latest interface mode, it sends IPC command to the PMC through PMC driver/API. The PMC acts as a proxy for R/W on behalf of the driver. - intel_set_reg_access(): Set the register access to the available TSN interface.

INTEL_PMC_IPC has depends on ACPI but selecting INTEL_PMC_IPC won't enforce it AFAIK. -- i. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
