From 16c4c52435cf8bb6e5986c14d36d93a0dd4c98df Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Tue, 13 Nov 2012 18:16:43 +0100 Subject: bindings: i2c: use consistent naming for i2c binding descriptions Filenames of devictree binding documentation seems to be arbitrary and for me it is unneeded hazzle to find the corresponding documentation for a specific driver. Naming the description the same as the driver is a lot easier and makes sense to me since the driver defines the binding it understands. Also, remove a reference in one source to the binding documentation, since path information easily gets stale.
