From 3b656fed6ff65d6d268da9ed0760c2a58d125771 Mon Sep 17 00:00:00 2001 From: Christian Daudt Date: Thu, 9 May 2013 22:21:01 +0100 Subject: ARM: 7716/1: bcm281xx: Add L2 support for Rev A2 chips Rev A2 SoCs have an unorthodox memory re-mapping and this needs to be reflected in the cache operations. This patch adds new outer cache functions for the l2x0 driver to support this SoC revision. It also adds a new compatible value for the cache to enable this functionality. Updates from V1: - remove section 1 altogether and note that in comments - simplify section selection caused by section 1 removal - BUG_ON just in case section 1 shows up Signed-off-by: Christian Daudt Reviewed-by: Will Deacon Acked-by: Olof Johansson Signed-off-by: Russell King --- Documentation/devicetree/bindings/arm/l2cc.txt | 3 +++ 1 file changed, 3 insertions(+) (limited to 'Documentation') diff --git a/Documentation/devicetree/bindings/arm/l2cc.txt b/Documentation/devicetree/bindings/arm/l2cc.txt index cbef09b5c8a7..69ddf9fad2dc 100644 --- a/Documentation/devicetree/bindings/arm/l2cc.txt +++ b/Documentation/devicetree/bindings/arm/l2cc.txt @@ -16,6 +16,9 @@ Required properties: performs the same operation).
