From d854cce18b416fea9d3619afa8d6fd25e319b9ec Mon Sep 17 00:00:00 2001 From: blogic Date: Mon, 17 Aug 2015 06:17:37 +0000 Subject: [PATCH 1/1] kernel: move linux, part-probe dt parsing in generic code The "linux,part-probe" dts parsing is a pretty neat generic feature. It has been posted to kernel.org and could easily be reused by all targets. This change moves the patch to the 3.18 and 4.1 generic folders, and makes the feature available to all platforms who may want to use it.
