From f31105347cc56c13d552b844ada04418769d875d Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Tue, 28 Apr 2015 12:17:50 +0200 Subject: [PATCH] irqchip: irqc: Remove platform data support As of commit 914d7d148411997c ("ARM: shmobile: r8a73a4: Remove legacy code"), the Renesas R-Mobile/R-Car interrupt controller is used with DT only, and interrupt numbers are thus always assigned automatically. Drop the platform data declaration and all related support code.
