---------------------------------------------------
1 BE 'big-endian'
2 LE 'little-endian'
3 Native 'native-endian'
For one device driver, which will run in different scenarios above
on different SoCs using the devicetree, we need one way to simplify
this.
Required properties:
- {big,little}-endian: these are boolean properties, if absent
meaning that the CPU and the Device are in the same endianness mode,
these properties are for register values and all the buffers only.
Optional properties:
- {big,little,native}-endian: these are boolean properties, if absent
then the implementation will choose a default based on the device
being controlled. These properties are for register values and all
the buffers only. Native endian means that the CPU and device have
the same endianness.
Examples:
Scenario 1 : CPU in LE mode & device in LE mode.

max9867 codec
This device supports I2C mode only.
Required properties:
- compatible : "maxim,max9867"
- reg : The chip select number on the I2C bus
Example:
&i2c {
max9867: max9867@0x18 {
compatible = "maxim,max9867";
reg = <0x18>;
};

max98926 audio CODEC
This device supports I2C.
Required properties:
- compatible : "maxim,max98926"
- vmon-slot-no : slot number used to send voltage information
or in inteleave mode this will be used as
interleave slot.
- imon-slot-no : slot number used to send current information
- interleave-mode : When using two MAX98926 in a system it is
possible to create ADC data that that will
overflow the frame size. Digital Audio Interleave
mode provides a means to output VMON and IMON data
from two devices on a single DOUT line when running
smaller frames sizes such as 32 BCLKS per LRCLK or
48 BCLKS per LRCLK.
- reg : the I2C address of the device for I2C
Example:
codec: max98926@1a {
compatible = "maxim,max98926";
vmon-slot-no = <0>;
imon-slot-no = <2>;
reg = <0x1a>;
};
