From mboxrd@z Thu Jan 1 00:00:00 1970 From: Frank.Li@nxp.com (Frank Li) Date: Tue, 5 Jan 2016 11:17:14 -0600 Subject: [PATCH v2 1/4] ARM: dts: imx7d: add arch timer Message-ID: <1452014237-12848-1-git-send-email-Frank.Li@nxp.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Frank Li 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.
