[PATCH v7 0/3] Broadcom FlexRM ring manager support

From: Anup Patel
Date: Wed Mar 29 2017 - 01:31:36 EST


The Broadcom FlexRM ring manager provides producer-consumer style
ring interface for offload engines on Broadcom iProc SoCs. We can
have one or more instances of Broadcom FlexRM ring manager in a SoC.

This patchset adds a mailbox driver for Broadcom FlexRM ring manager
which can be used by offload engine drivers as mailbox clients.

The Broadcom FlexRM mailbox driver is feature complete for RAID and
Crypto offload engines. We will have incremental patches in-future
for ring-level statistics using debugfs and minor optimizations.

This patchset is based on Linux-4.11-rc4 and it is also available
at flexrm-v7 branch of https://github.com/Broadcom/arm64-linux.git

- Rebased patches for Linux-4.11-rc4
