This patch adds the bus nodes for Exynos4210 SoC. Exynos4210 SoC has one power line for all buses to translate data between DRAM and sub-blocks. Following list specifies the detailed relation between DRAM and sub-blocks: - DMC/ACP clock for DMC (Dynamic Memory Controller) - ACLK200 clock for LCD0 - ACLK100 clock for PERIL/PERIR/MFC(PCLK) - ACLK160 clock for CAM/TV/LCD0/LCD1 - ACLK133 clock for FSYS/GPS - GDL/GDR clock for LEFTBUS/RIGHTBUS - SCLK_MFC clock for MFC Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Reviewed-by: Krzysztof Kozlowski <redacted> --- arch/arm/boot/dts/exynos4210.dtsi | 159 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 159 insertions(+)
