From ce23eb93b8ef9f9cb8993d3633bca525042b4cab Mon Sep 17 00:00:00 2001 From: Chanwoo Choi Date: Thu, 8 Dec 2016 13:58:10 +0900 Subject: [PATCH] arm64: dts: exynos: Add bus nodes using VDD_INT for Exynos5433 This patch adds the AMBA AXI bus nodes using VDD_INT for Exynos5433 SoC. Following list specify the detailed correlation between sub-block and clock: - CLK_ACLK_G2D_{400|266} : Bus clock for G2D (2D graphic engine) - CLK_ACLK_MSCL_400 : Bus clock for MSCL (Memory to memory Scaler) - CLK_ACLK_GSCL_333 : Bus clock for GSCL (General Scaler) - CLK_SCLK_JPEG_MSCL : Bus clock for JPEG - CLK_ACLK_MFC_400 : Bus clock for MFC (Multi Format Codec) - CLK_ACLK_HEVC_400 : Bus clock for HEVC (High Efficient Video Codec) - CLK_ACLK_BUS0_400 : NoC's (Network On Chip) bus clock for PERIC/PERIS/FSYS/MSCL - CLK_ACLK_BUS1_400 : NoC's bus clock for MFC/HEVC/G3D - CLK_ACLK_BUS2_400 : NoC's bus clock for GSCL/DISP/G2D/CAM0/CAM1/ISP Signed-off-by: Chanwoo Choi Signed-off-by: Krzysztof Kozlowski --- arch/arm64/boot/dts/exynos/exynos5433-bus.dtsi | 197 +++++++++++++++++++++++++ arch/arm64/boot/dts/exynos/exynos5433.dtsi | 1 + 2 files changed, 198 insertions(+) create mode 100644 arch/arm64/boot/dts/exynos/exynos5433-bus.dtsi diff --git a/arch/arm64/boot/dts/exynos/exynos5433-bus.dtsi b/arch/arm64/boot/dts/exynos/exynos5433-bus.dtsi new file mode 100644 index 0000000..c42dc39 --- /dev/null +++ b/arch/arm64/boot/dts/exynos/exynos5433-bus.dtsi @@ -0,0 +1,197 @@ +/* + * Samsung's Exynos5433 SoC Memory interface and AMBA bus device tree source + * + * Copyright (c) 2016 Samsung Electronics Co., Ltd. + * Chanwoo Choi + * + * This program is free software;
