Here I applied address-cells and size-cells to show which type accelerometer's reg property has, like this one: i2c { #address-cells = <1>; #size-cells = <0>; accelerometer@62 { compatible = "memsensing,msa311"; reg = <0x62>; Above accelerometer@62 is child node for i2c bus node, so address and size cells mean accelerometer reg format. Am I missing something? -- Thank you, Dmitry
