Exynos4x12 SoC has two memory bus 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/ACP 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/PERIR/MFC(PCLK) - ACLK160 clock : CAM/TV/LCD - ACLK133 clock : FSYS - GDL/GDR clock : leftbus/rightbus - SCLK_MFC clock : MFC Cc: Kukjin Kim Cc: Myungjoo Ham Cc: Kyungmin Park Signed-off-by: Chanwoo Choi --- arch/arm/boot/dts/exynos4x12.dtsi | 121 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 121 insertions(+) diff --git a/arch/arm/boot/dts/exynos4x12.dtsi b/arch/arm/boot/dts/exynos4x12.dtsi index 93b7040..44f6272 100644 --- a/arch/arm/boot/dts/exynos4x12.dtsi +++ b/arch/arm/boot/dts/exynos4x12.dtsi @@ -31,6 +31,127 @@ mshc0 = &mshc_0; }; + memory_bus_mif: memory_bus@0 { + compatible = "samsung,exynos-memory-bus"; + + operating-points = < + 400000 1100000 + 200000 1000000 + 160000 950000 + 133000 950000 + 100000 950000>; + status = "disabled"; + + blocks { + dmc_block: memory_bus_block1 { + clocks = <&clock CLK_DIV_DMC>; + clock-names = "memory-bus"; + frequency = < + 400000 + 200000 + 160000 + 133000 + 100000>; + }; + + acp_block: memory_bus_block2 { + clocks = <&clock CLK_DIV_ACP>; + clock-names = "memory-bus"; + frequency = < + 200000 + 160000 + 133000 + 133000 + 100000>; + }; + + c2c_block: memory_bus_block3 { + clocks = <&clock CLK_DIV_C2C>; + clock-names = "memory-bus"; + frequency = < + 400000 + 200000 + 160000 + 133000 + 100000>; + }; + }; + }; + + memory_bus_int: memory_bus@1 { + compatible = "samsung,exynos-memory-bus"; + + operating-points = < + 200000 1000000 + 160000 950000 + 133000 925000 + 100000 900000>; + + status = "disabled"; + + blocks { + peri_block: memory_bus_block1 { + clocks = <&clock CLK_ACLK100>; + clock-names = "memory-bus"; + frequency = < + 100000 + 100000 + 100000 + 100000>; + }; + + fsys_block: memory_bus_block2 { + clocks = <&clock CLK_ACLK133>; + clock-names = "memory-bus"; + frequency = < + 133000 + 133000 + 100000 + 100000>; + }; + + display_block: memory_bus_block3 { + clocks = <&clock CLK_ACLK160>; + clock-names = "memory-bus"; + frequency = < + 160000 + 160000 + 133000 + 100000>; + }; + + leftbus_block: memory_bus_block4 { + clocks = <&clock CLK_DIV_GDL>; + clock-names = "memory-bus"; + frequency = < + 200000 + 160000 + 133000 + 100000>; + }; + + rightbus_block: memory_bus_block5 { + clocks = <&clock CLK_DIV_GDR>; + clock-names = "memory-bus"; + frequency = < + 200000 + 160000 + 133000 + 100000>; + }; + + mfc_block: memory_bus_block6 { + clocks = <&clock CLK_SCLK_MFC>; + clock-names = "memory-bus"; + frequency = < + 200000 + 160000 + 133000 + 100000>; + }; + }; + }; + sysram@02020000 { compatible = "mmio-sram"; reg = <0x02020000 0x40000>; -- 1.8.5.5
