From 404f85e5ea9ee93c2a52e01b98acafa010c4d013 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Tue, 9 Jun 2009 22:12:33 +0200 Subject: v4l2: add new s_config subdev ops and v4l2_i2c_new_subdev_cfg/board calls From: Hans Verkuil Add a new s_config core ops call: this is called with the irq and platform data to be used to initialize the subdev. Added new v4l2_i2c_new_subdev_cfg and v4l2_i2c_new_subdev_board calls that allows you to pass these new arguments. The existing v4l2_i2c_new_subdev functions were modified to also call s_config. In the future the existing v4l2_i2c_new_subdev functions will be replaced by a single v4l2_i2c_new_subdev function similar to v4l2_i2c_new_subdev_cfg but without the irq and platform_data arguments.
