From d12d42f744f805a9ccc33cd76f04b237cd83ce56 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Tue, 13 Apr 2010 16:12:28 -0700 Subject: i2c/of: Allow device node to be passed via i2c_board_info The struct device_node *of_node pointer is moving out of dev->archdata and into the struct device proper. of_i2c.c needs to set the of_node pointer before the device is registered. Since the i2c subsystem doesn't allow 2 stage allocation and registration of i2c devices, the of_node pointer needs to be passed via the i2c_board_info structure so that it is set prior to registration. This patch adds of_node to struct i2c_board_info (conditional on CONFIG_OF), sets of_node in i2c_new_device(), and modifies of_i2c.c to use the new parameter. The calling of dev_archdata_set_node() from of_i2c will be removed in a subsequent patch when of_node is removed from archdata and all users are converted over.
