** Description changed:
[Impact]
When amd-sfh is loaded the sensors connected do not change values at all
(ALS sensor).
+ Here is the monitor sensors output, which doesn't change.

Waiting for iio-sensor-proxy to appear
- +++ iio-sensor-proxy appeared

+ +++ iio-sensor-proxy appeared
+ === No accelerometer
+ === Has ambient light sensor (value: 0.000000, unit: lux)
[Fix]
+ The SRU contains two fixes:
+ 1. increasing sensor command timeout from from 800000 to 1600000.
+ 2. using first valid 15 bits only ALS max illuminance values.
+
+
[Test]
+ This is requested by AMD. This was also verified by an AMD's engineer
+ on CRB.
+
[Where problems could occur]
+
+ Low. The patches only increase timeout value and discard an invalid
+ bit.
