^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) Required properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) - compatible: Must be "lltc,ltc2990"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) - reg: I2C slave address
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) - lltc,meas-mode:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) 	An array of two integers for configuring the chip measurement mode.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 	The first integer defines the bits 2..0 in the control register. In all
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) 	cases the internal temperature and supply voltage are measured. In
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) 	addition the following input measurements are enabled per mode:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) 		0: V1, V2, TR2
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 		1: V1-V2, TR2
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 		2: V1-V2, V3, V4

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) 	The second integer defines the bits 4..3 in the control register. This
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) 	allows a subset of the measurements to be enabled:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) 		0: Internal temperature and supply voltage only
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) 		1: TR1, V1 or V1-V2 only per mode
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) 		2: TR2, V3 or V3-V4 only per mode
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) 		3: All measurements per mode
