From 81f35ed60fabfd5b310263a7202595913529ee74 Mon Sep 17 00:00:00 2001 From: Sudeep KarkadaNagesha Date: Mon, 17 Jun 2013 12:58:45 +0100 Subject: [PATCH] driver/core: cpu: initialize of_node in cpu's device struture CPUs are also registered as devices but the of_node in these cpu devices are not initialized. Currently different drivers requiring to access cpu device node are parsing the nodes themselves and initialising the of_node in cpu device. The of_node in all the cpu devices needs to be initialized properly and at one place. The best place to update this is CPU subsystem driver when registering the cpu devices. The OF/DT core library now provides of_get_cpu_node to retrieve a cpu device node for a given logical index by abstracting the architecture specific details. This patch uses of_get_cpu_node to assign of_node when registering the cpu devices.
