From 68608b5e5063dd12942f1118286c6f595d0c4a05 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Mon, 10 Jun 2019 12:18:56 +0300 Subject: firmware: ti_sci: Add resource management APIs for ringacc, psi-l and udma Configuration of NAVSS resource, like rings, UDMAP channels, flows and PSI-L thread management need to be done via TISCI. Add the needed structures and functions for NAVSS resource configuration of the following: Rings from Ring Accelerator PSI-L thread management UDMAP tchan, rchan and rflow configuration.
