From a3cde14f5a9ef0bca820341cbbd6d5cfb80451fc Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Tue, 16 Aug 2016 14:49:16 +0300 Subject: [PATCH] arc: use patched .dts from sources Instead of using off-the-tree .dts files for ARC boards we're switching to use in-tree ones. And for that to work properly we apply upstream patch that adds currently missing "model" property. Upstream patch and discussion could be found here: http://lists.infradead.org/pipermail/linux-snps-arc/2016-August/001394.html Signed-off-by: Alexey Brodkin Cc: Jonas Gorski Cc: John Crispin --- target/linux/arc770/dts/axc001.dtsi | 100 -------- target/linux/arc770/dts/axs101.dts | 22 -- target/linux/arc770/dts/axs10x_mb.dtsi | 225 ------------------ target/linux/arc770/dts/nsim_700.dts | 71 ------ target/linux/arc770/dts/skeleton.dtsi | 37 --- target/linux/arc770/image/Makefile | 2 +- target/linux/archs38/dts/axc003_idu.dtsi | 126 ---------- target/linux/archs38/dts/axs103_idu.dts | 25 -- target/linux/archs38/dts/axs10x_mb.dtsi | 225 ------------------ target/linux/archs38/dts/nsim_hs_idu.dts | 73 ------ target/linux/archs38/dts/skeleton.dtsi | 37 --- target/linux/archs38/image/Makefile | 2 +- .../096-arc-add-model-property-in-dts.patch | 192 +++++++++++++++ 13 files changed, 194 insertions(+), 943 deletions(-) delete mode 100644 target/linux/arc770/dts/axc001.dtsi delete mode 100644 target/linux/arc770/dts/axs101.dts delete mode 100644 target/linux/arc770/dts/axs10x_mb.dtsi delete mode 100644 target/linux/arc770/dts/nsim_700.dts delete mode 100644 target/linux/arc770/dts/skeleton.dtsi delete mode 100644 target/linux/archs38/dts/axc003_idu.dtsi delete mode 100644 target/linux/archs38/dts/axs103_idu.dts delete mode 100644 target/linux/archs38/dts/axs10x_mb.dtsi delete mode 100644 target/linux/archs38/dts/nsim_hs_idu.dts delete mode 100644 target/linux/archs38/dts/skeleton.dtsi create mode 100644 target/linux/generic/patches-4.4/096-arc-add-model-property-in-dts.patch diff --git a/target/linux/arc770/dts/axc001.dtsi b/target/linux/arc770/dts/axc001.dtsi deleted file mode 100644 index 420dcfde28..0000000000 --- a/target/linux/arc770/dts/axc001.dtsi +++ /dev/null @@ -1,100 +0,0 @@ -/* - * Copyright (C) 2013-15 Synopsys, Inc.
