Re: Fwd: [PATCH 1/2] hwmon: (lm75) Add support for TMP75B

[Iker Perez del Palomar]

Hi,


Thank you for the review, I will submit a fixed patch soon. I have one
question before doing it though, after running scrips/chechpatch.sh I
obtain the next message:

WARNING: DT compatible string "ti,tmp75b" appears un-documented -- check
./Documentation/devicetree/bindings/
#83: FILE: drivers/hwmon/lm75.c:549:
+		.compatible = "ti,tmp75b",

total: 0 errors, 1 warnings, 60 lines checked

So I added the next in
"Documentation/devicetree/bindings/trivial-devices.yaml":

	- ti,amc6821
	# I2C Touch-Screen Controller
  	- ti,tsc2003
+ 	# Digital Temperature Sensor with Two-Wire Interface and Alert
+ 	- ti,tmp75b
  	# Low Power Digital Temperature Sensor with SMBUS/Two Wire Serial
Interface
  	- ti,tmp102
  	# Low Power Digital Temperature Sensor with SMBUS/Two Wire Serial
Interface


Is that the proper procedure??

Thank you for your help.



Regards,


Iker
