[U-Boot] hwmon in current uboot

[Joe Rutledge]

Hi,

Apologies in advance if this is answered somewhere else, but I had no 
luck finding information about it.

I'm moving from an older version of u-boot (2016) to a current one. Some 
of the patches I had against the old uboot included work in the hwmon 
subdirectory. These patches now obviously fail as this whole set of 
functionality appears to have been removed.

Am I missing something, or does u-boot no longer support any of these 
devices? Alternatively, is there a way I should reintroduce it for my board.

Many thanks in advance,

Joe

Looking at the git log for some of the files that were in the 
drivers/hwmon directory (git log — path/to/filename) then they were 
removed in May 2017 in favour of the driver model and UCLASS_THERMAL 
which is located in drivers/thermal.

Unfortunately, it doesn’t look as though those I2C based devices got 
converted.

Thanks very much for the response!

So I guess I need to write something new under the new UCLASS_THERMAL 
model for my part. Any gotchas in there I should know about?
