Subject: [PATCH v2 0/6] This series adds SMP support for the MediaTek MT6580.
Date: Fri, 10 Jul 2015 14:04:03 +0800 [thread overview]
Message-ID: <1436508249-49338-1-git-send-email-scott.shu@mediatek.com> (raw)
In-Reply-To: <Scott Shu <scott.shu@gmail.com>
This patchset adds support SMP on MediaTek MT6580 Cortex-A7 quad-core SoC.
This is based on v4.1-rc1 and following patch series:
(1) Yingjoe Chen's "Add SMP bringup support for mt65xx socs" [1]
(2) Mars Cheng's "Add mt6580 basic chip support" [2]
(3) Sascha Hauer's "Mediatek SCPSYS power domain support" [3]
The secondary cores are power off as default on MT6580, this change adds
a new enable-method to turn on power to the cores during booting process.
The System Power Manager (SPM) inside the SCPSYS is for the CPU MTCMOS
power domain control. Please check [3] for more information about SCPSYS.

[2] https://lkml.org/lkml/2015/7/7/122
[3] https://lkml.org/lkml/2015/6/9/172
Change in v2:
1. Rebase to 4.2-rc1
2. Fix using usleep() in atomic context
3. Put a timeout in cpu power on/off sequence
4. Fix some coding style
