From 22697acdd72d6749d603cb861d4f6c1c2b583c1b Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Thu, 19 Nov 2015 09:42:49 +0900 Subject: dt-bindings: Consolidate SRAM bindings from all vendors SRAM bindings for various SoCs, using the mmio-sram genalloc API, are spread over different places - per SoC vendor. Since all of these are quite similar (they depend on mmio-sram) move them to a common place.
