Kernel-4.18.0-80.el8_dw_mipi_dsi_rockchip

Rockchip specific extensions to the Synopsys Designware MIPI DSI

Required properties:

  • #address-cells: Should be <1>.
  • #size-cells: Should be <0>.
  • compatible: “rockchip,rk3288-mipi-dsi”, “snps,dw-mipi-dsi”.
        "rockchip,rk3399-mipi-dsi", "snps,dw-mipi-dsi".
    
  • reg: Represent the physical address range of the controller.
  • interrupts: Represent the controller’s interrupt to the CPU(s).
  • clocks, clock-names: Phandles to the controller’s pll reference
    clock(ref) and APB clock(pclk). For RK3399, a phy config clock
    (phy_cfg) and a grf clock(grf) are required. As described in [1].
  • rockchip,grf: this soc should set GRF regs to mux vopl/vopb.
  • ports: contain a port node with endpoint definitions as defined in [2].
    For vopb,set the reg = <0> and set the reg = <1> for vopl.

Optional properties:

  • power-domains: a phandle to mipi dsi power domain node.
  • resets: list of phandle + reset specifier pairs, as described in [3].
  • reset-names: string reset name, must be “apb”.
