From 15527fee767f592d894d954d78cf8af3685cda6d Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Thu, 14 Apr 2022 13:48:03 -0500 Subject: [PATCH] ASoC: SOF: add definitions for different IPC types MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Add enum type to allow for different types of IPCs. The IPCv4 is intended for Intel only as a convergence path with firmware used in Windows. Follow-up patches will introduce different abstractions with .ops and different search paths for firmware and topology files.
