[PATCH 19/46] dt-bindings:iio:light:upisemi,us51882: txt to yaml conversion.

[Jonathan Cameron <jic23@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

I don't have an up to date address for Adriana Reus so I've put myself
as the binding maintainer for this one.  I'm happy to hand over to Adriana
or anyone else who wants take it on!

This has a lot of optional tuning parameters. The docs are modified to try
and put the default values in the description of each one rather than a
forwards reference to the example.

-* UPISEMI us5182d I2C ALS and Proximity sensor
-
-Required properties:
-- compatible: must be "upisemi,usd5182"
-- reg: the I2C address of the device
-
-Optional properties:
-- upisemi,glass-coef: glass attenuation factor - compensation factor of
-                      resolution 1000 for material transmittance.
-
-- upisemi,dark-ths: array of 8 elements containing 16-bit thresholds (adc
-                    counts) corresponding to every scale.
-
-- upisemi,upper-dark-gain: 8-bit dark gain compensation factor(4 int and 4
-                           fractional bits - Q4.4) applied when light > threshold
-
-- upisemi,lower-dark-gain: 8-bit dark gain compensation factor(4 int and 4
-                           fractional bits - Q4.4) applied when light < threshold
-
-- upisemi,continuous: This chip has two power modes: one-shot (chip takes one
-                      measurement and then shuts itself down) and continuous (
-                      chip takes continuous measurements). The one-shot mode is
-                      more power-friendly but the continuous mode may be more
-                      reliable. If this property is specified the continuous
-                      mode will be used instead of the default one-shot one for
-                      raw reads.
-
-If the optional properties are not specified these factors will default to the
-values in the below example.
-The glass-coef defaults to no compensation for the covering material.
-The threshold array defaults to experimental values that work with US5182D
-sensor on evaluation board - roughly between 12-32 lux.
-There will be no dark-gain compensation by default when ALS > thresh
-(0 * dark-gain), and a 1.35 compensation factor when ALS < thresh.
-
-Example:
-
-    usd5182@39 {
-                compatible = "upisemi,usd5182";
-                reg = <0x39>;
-                upisemi,glass-coef = < 1000 >;
-                upisemi,dark-ths = /bits/ 16 <170 200 512 512 800 2000 4000 8000>;
-                upisemi,upper-dark-gain = /bits/ 8 <0x00>;
-                upisemi,lower-dark-gain = /bits/ 8 <0x16>;
