From de1965159a34951a86267d13db4f2a67234139d3 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Thu, 12 May 2016 01:36:40 +0300 Subject: [PATCH] rcar: src: skip disabled-SRC nodes The current device tree representation of the R-Car Sample Rate Converters (SRC) assumes that they are numbered consecutively, starting from 0. Alas, this is not the case with the R8A7794 SoC where SRC0 isn't present. In order to keep the existing device trees working, I'm suggesting to use a disabled node for SRC0. Teach the SRC probe to just skip disabled nodes.
