- col-scan-delay-us: delay, measured in microseconds, that is needed
before we can scan keypad after activating column gpio

Example:
matrix-keypad {

+- beeper-hz: bell frequency in Hz
Example:
- adi,conversion-interval: : 0 : convert one time only
1-255: 515us + val * 35us (up to 9.440ms)
This property has to be a '/bits/ 8' value
+- gpio-controller : Switch AUX/VBAT/GPIO pin to GPIO mode
Example:
adi,averaging = /bits/ 8 <1>;
adi,conversion-interval = /bits/ 8 <255>;

+
+Required properties:
+- compatible: must be "maxim,max11801"
+- reg: i2c slave address
+- interrupt-parent: the phandle for the interrupt controller

+ "silead,gsl1688"
+ "silead,gsl3670"
