Subject: [PATCH v2] ARM: rockchip: convert smp bringup to CPU_METHOD_OF_DECLARE
Date: Thu, 27 Mar 2014 01:06:32 +0100 [thread overview]
Message-ID: <1878147.CvhHSZhTas@diego> (raw)
In-Reply-To: <2151573.evmqdkWnet@diego>
With the newly introduced CPU_METHOD_OF_DECLARE is not necessary anymore
to reference the relevant smp_ops in the board file, but instead it can
simply be set by the enable-method property of the cpu nodes.
Signed-off-by: Heiko Stuebner <heiko@sntech.de>
---
changes since v1:
- add a short description to the enable-method binding
