From 3bcca2c271259ab2c3b539f0afa17d0043854c01 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 30 Nov 2017 14:29:46 +0100 Subject: dt-bindings: eeprom: at25: Document device-specific compatible values Document the recommended presence of a device-specific compatible value, and list examples that are already in use or soon will be. This will allow checkpatch to validate compatible values in DTS. Update the example to match current best practices (generic node name, specific compatible value first).
