@swordow thanks for the work here.

Unfortunately, you have based your changes on the Linux in-tree it87driver, which is well behind the one in this repo, and as such can't be merged into here.

However, what actual chip are you attempting to enable with your board, as it may already exist within the repo, and just not yet be available in the Linux mainline.

What I would suggest is you download a fresh copy of this repo, build it as an external module, and then unload the standard kernel it87 module and install the one built in here, without the force_id option. It may just work.

If the one build from this repo doesn't automatically work, we can run a few other checks to see what is happening and then update this repo to handle it.

Again, thanks for you work, and lets see if we can get it to work for you.

Regards Frank

@swordow any update for this? If not, I'm going to reject this PR.

@frankcrawford
You are right. The actual chip is it8688 which is suppored in your repo and just not yet available in linux mainline. I will clone this repo and build as an external module later. I just think this patch may help some one that needs built in module in lts 5.15.x mainline, so i opend request. It does not matter if it is no necessary. Thanks~~

@swordow FYI a lot of the simple changes are in this version will be in the kernel for 6.4, and 6.5. There is one item (multi-bank support) that the it8688 needs, that will be harder to get in, and so may even take until 6.6.

Getting it back ported will always be a much bigger issue. They normally will only take bug fixes, not enhancements.
