Marvell Armada CP110 System Controller 0 ======================================== The CP110 is one of the two core HW blocks of the Marvell Armada 7K/8K SoCs. It contains two sets of system control registers, System Controller 0 and System Controller 1. This Device Tree binding allows to describe the first system controller, which provides registers to configure various aspects of the SoC. For the top level node: - compatible: must be: "syscon", "simple-mfd"; - reg: register area of the CP110 system controller 0 Clocks: ------- The Device Tree node representing this System Controller 0 provides a number of clocks: - a set of core clocks - a set of gatable clocks Those clocks can be referenced by other Device Tree nodes using two cells: - The first cell must be 0 or 1. 0 for the core clocks and 1 for the gatable clocks. - The second cell identifies the particular core clock or gatable clocks. The following clocks are available: - Core clocks - 0 0 APLL - 0 1 PPv2 core - 0 2 EIP - 0 3 Core - 0 4 NAND core - 0 5 SDIO core - Gatable clocks - 1 0 Audio - 1 1 Comm Unit - 1 2 NAND - 1 3 PPv2 - 1 4 SDIO - 1 5 MG Domain - 1 6 MG Core - 1 7 XOR1 - 1 8 XOR0 - 1 9 GOP DP - 1 11 PCIe x1 0 - 1 12 PCIe x1 1 - 1 13 PCIe x4 - 1 14 PCIe / XOR - 1 15 SATA - 1 16 SATA USB - 1 17 Main - 1 18 SD/MMC/GOP - 1 21 Slow IO (SPI, NOR, BootROM, I2C, UART) - 1 22 USB3H0 - 1 23 USB3H1 - 1 24 USB3 Device - 1 25 EIP150 - 1 26 EIP197 Required properties: - compatible: must be: "marvell,cp110-clock" - #clock-cells: must be set to 2 Example: cpm_syscon0: system-controller@440000 { compatible = "syscon", "simple-mfd"; reg = <0x440000 0x1000>; cpm_clk: clock { compatible = "marvell,cp110-clock"; #clock-cells = <2>; }; };
