1wire library install for Enclosure Plugin

Having problem getting 1wire library installed to support DS1820 temp sensor. I followed the following steps:

  1. 'dtoverlay=w1-gpio' entered as a line item in config.txt

  2. rebooted the RaspPi.(ver4)

  3. connected to RasPi using Putty for a terminal session

  4. issued 'dmesg|grep gpio' command

  5. the following text was returned:
    [ 1.568531] gpiomem-bcm2835 fe200000.gpiomem: Initialised: Registers at 0xfe200000
    [ 5.290590] gpio-4 (onewire@0): enforced open drain please flag it properly in DT/ACPI DSDT

  6. I think that I should have seen the following line:
    [ 3.030368] w1-gpio onewire@0: gpio pin 4, external pullup pin -1, parasitic power 0

Any suggestions for a path forward and a fix? Thanks.
