From: Bhupesh Sharma Date: Fri, 23 Oct 2015 19:31:53 +0000 (+0530) Subject: Documentation/dts: Move FSL board-specific bindings out of /powerpc X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=a2cce7a9f1b8cc3d4edce106fb971529f1d4d9ce;p=deliverable%2Flinux.git Documentation/dts: Move FSL board-specific bindings out of /powerpc Since the same board components can be used across ARM and PPC board families, this patch moves the FSL board-specific bindings out of bindings/powerpci. While at it, this patch also adds the bindings for QIXIS FPGA controller found on FSL LS2080A boards. These boards have an on-board FPGA/CPLD connected to the IFC controller.
