i2c_register_board_info

I2C_REGISTER_BOARD_I(9) 				      I2C and SMBus Subsystem					   I2C_REGISTER_BOARD_I(9)

NAME

       i2c_register_board_info - statically declare I2C devices

SYNOPSIS

       int i2c_register_board_info(int busnum, struct i2c_board_info const * info, unsigned len);

ARGUMENTS

       busnum
	   identifies the bus to which these devices belong

       info
	   vector of i2c device descriptors

       len
	   how many descriptors in the vector; may be zero to reserve the specified bus number.

DESCRIPTION

       Systems using the Linux I2C driver stack can declare tables of board info while they initialize. This should be done in board-specific init
       code near arch_initcall time, or equivalent, before any I2C adapter driver is registered. For example, mainboard init code could define
       several devices, as could the init code for each daughtercard in a board stack.

       The I2C devices will be created later, after the adapter for the relevant bus has been registered. After that moment, standard driver model
       tools are used to bind "new style" I2C drivers to the devices. The bus number for any device declared using this routine is not available
       for dynamic allocation.

       The board info passed can safely be __initdata, but be careful of embedded pointers (for platform_data, functions, etc) since that won't be
       copied.
