 * struct lm3530_platform_data
 * @mode: mode of operation i.e. Manual, ALS or PWM
 * @als_input_mode: select source of ALS input - ALS1/2 or average
 * @max_current: full scale LED current
 * @pwm_pol_hi: PWM input polarity - active high/active low
 * @als_avrg_time: ALS input averaging time
 * @brt_ramp_law: brightness mapping mode - exponential/linear
 * @brt_ramp_fall: rate of fall of led current
 * @brt_ramp_rise: rate of rise of led current
 * @als1_resistor_sel: internal resistance from ALS1 input to ground
 * @als2_resistor_sel: internal resistance from ALS2 input to ground
 * @als_vmin: als input voltage calibrated for max brightness in mV
 * @als_vmax: als input voltage calibrated for min brightness in mV
 * @brt_val: brightness value (0-127)
 * @pwm_data: PWM control functions (only valid when the mode is PWM)
