Exynos3250 has following memory buses to translate data between DRAM and eMMC/sub-IPs. Following list specifies the detailed relation between memory bus clock and DMC IP in MIF (Memory Interface) block: - DMC clock : DMC (Dynamic Memory Controller) Following list specifies the detailed relation between memory bus clock and sub-IPs in INT (Internal) block: - ACLK100 clock : PERIL - ACLK160 clock : LCD0 - ACLK200 clock : FSYS - ACLK266 clock : ISP - GDL/GDR clock : leftbus/rightbus - SCLK_MFC clock : MFC Cc: Kukjin Kim Cc: Myungjoo Ham Cc: Kyungmin Park Signed-off-by: Chanwoo Choi Acked-by: Kyungmin Park --- arch/arm/boot/dts/exynos3250.dtsi | 125 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 125 insertions(+) diff --git a/arch/arm/boot/dts/exynos3250.dtsi b/arch/arm/boot/dts/exynos3250.dtsi index 9ed1260..3eaed53 100644 --- a/arch/arm/boot/dts/exynos3250.dtsi +++ b/arch/arm/boot/dts/exynos3250.dtsi @@ -99,6 +99,131 @@ }; }; + memory_bus_mif: memory_bus@0 { + compatible = "samsung,exynos-memory-bus"; + + operating-points = < + 400000 875000 + 200000 800000 + 133000 800000 + 100000 800000 + 50000 800000>; + status = "disabled"; + + blocks { + dmc_block: memory_bus_block1 { + clocks = <&cmu_dmc CLK_DIV_DMC>; + clock-names = "memory-bus"; + frequency = < + 400000 + 200000 + 133000 + 100000 + 50000>; + }; + }; + }; + + memory_bus_int: memory_bus@1 { + compatible = "samsung,exynos-memory-bus"; + + operating-points = < + 400000 950000 + 200000 950000 + 133000 925000 + 100000 850000 + 80000 850000 + 50000 850000>; + + status = "disabled"; + + blocks { + peril_block: memory_bus_block1 { + clocks = <&cmu CLK_DIV_ACLK_100>; + clock-names = "memory-bus"; + frequency = < + 100000 + 100000 + 100000 + 100000 + 50000 + 50000>; + }; + + lcd0_block: memory_bus_block2 { + clocks = <&cmu CLK_DIV_ACLK_160>; + clock-names = "memory-bus"; + frequency = < + 200000 + 160000 + 100000 + 80000 + 80000 + 50000>; + }; + + fsys_block: memory_bus_block3 { + clocks = <&cmu CLK_DIV_ACLK_200>; + clock-names = "memory-bus"; + frequency = < + 200000 + 200000 + 100000 + 80000 + 50000 + 50000>; + }; + + isp_block: memory_bus_block4 { + clocks = <&cmu CLK_DIV_ACLK_266>; + clock-names = "memory-bus"; + frequency = < + 300000 + 200000 + 133000 + 100000 + 50000 + 50000>; + }; + + leftbus_block: memory_bus_block5 { + clocks = <&cmu CLK_DIV_GDL>; + clock-names = "memory-bus"; + frequency = < + 200000 + 200000 + 133000 + 100000 + 100000 + 100000>; + }; + + rightbus_block: memory_bus_block6 { + clocks = <&cmu CLK_DIV_GDR>; + clock-names = "memory-bus"; + frequency = < + 200000 + 200000 + 133000 + 100000 + 100000 + 100000>; + }; + + mfc_block: memory_bus_block7 { + clocks = <&cmu CLK_SCLK_MFC>; + clock-names = "memory-bus"; + frequency = < + 200000 + 200000 + 200000 + 133000 + 100000 + 80000>; + }; + }; + }; + sysram@02020000 { compatible = "mmio-sram"; reg = <0x02020000 0x40000>; -- 1.8.5.5
