From 20b80942ef4e3156a1c4aa5628d1bcb3479812da Mon Sep 17 00:00:00 2001 From: Nishanth Menon Date: Wed, 16 Oct 2013 15:21:03 -0500 Subject: [PATCH] ARM: dts: OMAP3+: Add i2c aliases Currently, on OMAP5, i2c1 and i2c5 defer probe due to pinctrl dependencies. This changes the i2c ID each bus is registered with in i2c-dev interface. As a result of this, many userspace tools break and there is no consistent manner to fix the same if the i2c dev interface have no consistent numbering. Since this could happen for other OMAP derivatives, provide i2c alias for all OMAP3+ SoCs to allow ordering the i2c devices correctly.
