From 373c612d72461ddaea223592df31e62c934aae61 Mon Sep 17 00:00:00 2001 From: "Russell King (Oracle)" Date: Wed, 11 Jan 2023 10:54:21 +0000 Subject: i2c: add fwnode APIs Add fwnode APIs for finding and getting I2C adapters, which will be used by the SFP code. These are passed the fwnode corresponding to the adapter, and return the I2C adapter. It is the responsibility of the caller to find the appropriate fwnode. We keep the DT and ACPI interfaces, but where appropriate, recode them to use the fwnode interfaces internally.
