    1 Azoteq IQS550/572/525 Trackpad/Touchscreen Controller
    2 
    3 Required properties:
    4 
    5 - compatible                    : Must be equal to one of the following:
    6                                   "azoteq,iqs550"
    7                                   "azoteq,iqs572"
    8                                   "azoteq,iqs525"
    9 
   10 - reg                           : I2C slave address for the device.
   11 
   12 - interrupts                    : GPIO to which the device's active-high RDY
   13                                   output is connected (see [0]).
   14 
   15 - reset-gpios                   : GPIO to which the device's active-low NRST
   16                                   input is connected (see [1]).
   17 
   18 Optional properties:
   19 
   20 - touchscreen-min-x             : See [2].
   21 
   22 - touchscreen-min-y             : See [2].
   23 
   24 - touchscreen-size-x            : See [2]. If this property is omitted, the
   25                                   maximum x-coordinate is specified by the
   26                                   device's "X Resolution" register.
   27 
   28 - touchscreen-size-y            : See [2]. If this property is omitted, the
   29                                   maximum y-coordinate is specified by the
   30                                   device's "Y Resolution" register.
   31 
   32 - touchscreen-max-pressure      : See [2]. Pressure is expressed as the sum of
   33                                   the deltas across all channels impacted by a
   34                                   touch event. A channel's delta is calculated
   35                                   as its count value minus a reference, where
   36                                   the count value is inversely proportional to
   37                                   the channel's capacitance.
   38 
   39 - touchscreen-fuzz-x            : See [2].
   40 
   41 - touchscreen-fuzz-y            : See [2].
   42 
   43 - touchscreen-fuzz-pressure     : See [2].
   44 
   45 - touchscreen-inverted-x        : See [2]. Inversion is applied relative to that
   46                                   which may already be specified by the device's
   47                                   FLIP_X and FLIP_Y register fields.
   48 
   49 - touchscreen-inverted-y        : See [2]. Inversion is applied relative to that
   50                                   which may already be specified by the device's
   51                                   FLIP_X and FLIP_Y register fields.
   52 
   53 - touchscreen-swapped-x-y       : See [2]. Swapping is applied relative to that
   54                                   which may already be specified by the device's
   55                                   SWITCH_XY_AXIS register field.
