| Rockchip specific extensions to the Synopsys Designware MIPI DSI |
| ================================ |
| |
| Required properties: |
| - #address-cells: Should be <1>. |
| - #size-cells: Should be <0>. |
| - compatible: one of |
| "rockchip,px30-mipi-dsi", "snps,dw-mipi-dsi" |
| "rockchip,rk3288-mipi-dsi", "snps,dw-mipi-dsi" |
| "rockchip,rk3399-mipi-dsi", "snps,dw-mipi-dsi" |
| "rockchip,rk3568-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) when using an internal dphy 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. |
| - video port 0 for the VOP input, the remote endpoint maybe vopb or vopl |
| - video port 1 for either a panel or subsequent encoder |
| |
| Optional properties: |
| - phys: from general PHY binding: the phandle for the PHY device. |
| - phy-names: Should be "dphy" if phys references an external phy. |
| - #phy-cells: Defined when used as ISP phy, should be 0. |
| - 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". |
