From 0fe88461a0ec95a71950b4841f139a62ed63dc81 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Fri, 19 Aug 2016 19:19:39 +0200 Subject: mailbox: Add Tegra HSP driver This driver exposes a mailbox interface for interprocessor communication using the Hardware Synchronization Primitives (HSP) module's doorbell mechanism. There are multiple HSP instances and they provide additional features such as shared mailboxes, shared and arbitrated semaphores. A driver for a remote processor can use the mailbox client provided by the HSP driver and build an IPC protocol on top of this synchronization mechanism. Based on work by Joseph Lo .
