From 8ab8a31645b83c6446da6254c099032bab871b23 Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam Date: Mon, 17 Jul 2023 12:24:57 +0530 Subject: [PATCH] PCI: epf-mhi: Add support for SM8450 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Add support for Qualcomm Snapdragon SM8450 SoC to the EPF driver. SM8450 has the dedicated PID (0x0306) and supports eDMA. Currently, it has no fixed PCI class, so it is being advertised as "PCI_CLASS_OTHERS".
