From 250212b59a8e33f1b47f15ad9afa3db19ba0fc8d Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Tue, 27 Aug 2019 19:04:16 +0200 Subject: [PATCH] i2c: bcm2835: Add full name of devicetree node to adapter name Inspired by Lori Hikichi's patch for iproc, this adds the full name of the devicetree node to the adapter name. With the introduction of BCM2711 it's very difficult to distinguish between the multiple instances.
