From 1399fb87ea3e96d26398a16cb95dc395a68c51bc Mon Sep 17 00:00:00 2001 From: Govind Singh Date: Thu, 13 Aug 2020 12:04:24 +0300 Subject: [PATCH] ath11k: register MHI controller device for QCA6390 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Modem Host Interface (MHI) is a communication protocol to communicate with external Qualcomm modems and Wi-Fi chipsets over high speed peripheral buses. Even though MHI doesn’t dictate underlying physical layer, protocol and MHI stack is structured for PCI based devices. Register directly with MHI subsystem as a MHI device driver for firmware download to QCA6390.
