From 50bf17bd15d439b183a29bdb453b65217cfbef3b Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Tue, 20 Sep 2011 18:24:35 -0500 Subject: [PATCH] fdt: update fdt_alloc_phandle to use fdt_get_phandle The device tree compiler, dtc, can use "phandle" and/or "linux,phandle" properties to specify the phandle for any node. By default, it uses both, but "linux,phandle" is deprecated. One day, we'd like to stop using "linux,phandle", but U-boot needs to support both properties equally first. fdt_alloc_phandle() generates a unique phandle, but it was only checking the "linux,phandle" properties. Instead, we use fdt_get_phandle(), which checks both properties automatically. This ensures that we support dtbs that only use "phandle". The side-effect is that fdt_alloc_phandle() now takes twice as long, since it has to check for two properties instead of one in each node that it searches.
