From 539005ffc6260fcb3bb4171138be5f66a41185a9 Mon Sep 17 00:00:00 2001 From: Lori Hikichi Date: Thu, 8 Aug 2019 09:07:53 +0530 Subject: [PATCH] i2c: iproc: Add full name of devicetree node to adapter name Add the full name of the devicetree node to the adapter name. Without this change, all adapters have the same name making it difficult to distinguish between multiple instances. The most obvious way to see this is to use the utility i2c_detect. e.g. "i2c-detect -l" Before i2c-1 i2c Broadcom iProc I2C adapter I2C adapter i2c-0 i2c Broadcom iProc I2C adapter I2C adapter After i2c-1 i2c Broadcom iProc (i2c@e0000) I2C adapter i2c-0 i2c Broadcom iProc (i2c@b0000) I2C adapter Now it is easy to figure out which adapter maps to a which DT node.
