Subject: [PATCH v2 4/4] arm: zynq: Enable arm_global_timer
Date: Wed, 18 Sep 2013 11:48:38 -0700 [thread overview]
Message-ID: <1379530118-22813-5-git-send-email-soren.brinkmann@xilinx.com> (raw)
In-Reply-To: <1379530118-22813-1-git-send-email-soren.brinkmann@xilinx.com>
Zynq is based on an ARM Cortex-A9 MPCore, which features the
arm_global_timer in its SCU. Therefore enable the timer for Zynq.

v2:
- rename DT node: global_timer@... => timer@...
- add Daniel's ACK
