Subject: [PATCH v2 1/4] ARM: dts: imx7d: add arch timer
Date: Tue, 5 Jan 2016 11:17:14 -0600 [thread overview]
Message-ID: <1452014237-12848-1-git-send-email-Frank.Li@nxp.com> (raw)
From: Frank Li <Frank.Li@freescale.com>
Since uboot v2016.01-rc2, which supported basic psci for i.mx7d.
So imx7d's second core can be enabled by psci.
Without arch timer, every timer event will be boardcasted to each core.
arch timer has local timer irq for each core.
Signed-off-by: Frank Li <Frank.Li@freescale.com>

Change from v1 to v2:
* refine commit message show the relationship between smp and arch timer
