From 7132b9fd68a1c76bf557d56dd62756a6607cf761 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 26 Jan 2015 20:29:37 -0700 Subject: dm: i2c: dts: Support an offset-len device tree property Since U-Boot can support different offset lengths (0-4 bytes), add a device tree property to specify this. This avoids hard-coding it in the driver.
