[PATCH v2 0/5] Sunxi: Add SMP support on A83T
From: MylÃne Josserand
Date: Fri Dec 29 2017 - 05:55:39 EST
This is a V2 of my series that adds SMP support for Allwinner sun8i-a83t
with MCPM (Multi-Cluster Power Management).
Based on last linux-next (next-20171222).
Changes since v1:
- Add Chen Yu's patch in my series (see path 01)
- Add new compatibles for prcm and cpucfg registers for sun8i-a83t.
Create two functions to separate the DT parsing of sun9i-a80 and
- Thanks to Maxime's review: order device tree's nodes according
to physical addresses, remove unused label and fix registers' sizes.
Update the commit log and commit title of my last patch (see
Patch 01: Patch from Chen Yu Tsai that adds SMP support on A80
Patch 02: Convert the MCPM driver to use it for A83T. This SoC has a
bit flip that needs to be handled.
Patch 03: Add registers nodes (prcm, cpucfg and r_cpucfg) needed
Patch 04: Add CCI-400 node for a83t.
Patch 05: Fix the use of virtual timers that hangs the kernel in
case of SMP support.
If you have any remarks/questions, let me know.
Thank you in advance,
