-/**
- * struct pcf857x_platform_data - data to set up pcf857x driver
- * @gpio_base: number of the chip's first GPIO
- * @n_latch: optional bit-inverse of initial register value; if
- *	you leave this initialized to zero the driver will act
- *	like the chip was just reset
- * @setup: optional callback issued once the GPIOs are valid
- * @teardown: optional callback issued before the GPIOs are invalidated
- * @context: optional parameter passed to setup() and teardown()
- *
- * In addition to the I2C_BOARD_INFO() state appropriate to each chip,
- * the i2c_board_info used with the pcf875x driver must provide its
- * platform_data (pointer to one of these structures) with at least
- * the gpio_base value initialized.
- *
- * The @setup callback may be used with the kind of board-specific glue
- * which hands the (now-valid) GPIOs to other drivers, or which puts
- * devices in their initial states using these GPIOs.
- *
- * These GPIO chips are only "quasi-bidirectional"; read the chip specs
- * to understand the behavior.  They don't have separate registers to
- * record which pins are used for input or output, record which output
- * values are driven, or provide access to input values.  That must be
- * inferred by reading the chip's value and knowing the last value written
- * to it.  If you leave n_latch initialized to zero, that last written
- * value is presumed to be all ones (as if the chip were just reset).
