According the their datasheets: - TMP401, TMP411 and TMP43x support extended temperature range; - TMP411 and TMP43x support n-factor correction; - TMP43x support beta compensation. In order to make it possible for users to enable these features and set up them based on their needs, this patch series adds the following devicetree bindings: - ti,extended-range-enable; - ti,n-factor; - ti,beta-compensation. In the meanwhile, tmp401 driver reads them and configures the coressponding registers accordingly. v4: - just add reviewed-by, no change on code. v3: - dt-bindings: remove unused [address|size]_cells and ti,beta-compensation.items from ti,tmp401.yaml; - dt-bindings: change ti,n-factor range to [-128, 127]; - tmp401.c: instead of u32, use s32 for ti,n-factor. v2: - dt-bindings: fix format and describe hardware properties instead of programming models in ti,tmp401.yaml.
