Request to adapt the compilation of shutuo-v8-rk3288 version armbian

[Squealing 9059]

I have dtb files used by manufacturers for compiling on the Android 5.1 system (OEM versions 2.17 and 2.19). It differs from boards like the firefly, for example: using a 100 Mbps network port, USB GPIO uses <0x50 0x0c 0x00>.

Can anyone help with adapting this board? I want to compile it for armbian.

2.17.dtb 2.19.dtb

Find a board similar to yours and make the necessary adaptations.

and on Linux Rockchip:

Quote

    gpio0: gpio@fdd60000 {
            compatible = "rockchip,gpio-bank";
            reg = <0x0 0xfdd60000 0x0 0x100>;
            interrupts = <GIC_SPI 33 IRQ_TYPE_LEVEL_HIGH>;
            clocks = <&pmucru PCLK_GPIO0>, <&pmucru DBCLK_GPIO0>;
            gpio-controller;
            gpio-ranges = <&pinctrl 0 0 32>;
            #gpio-cells = <2>;
            interrupt-controller;
            #interrupt-cells = <2>;
        };

 

The following example could be used to describe GPIO pins used as device enable
and bit-banged data signals:

    gpio1: gpio1 {
        gpio-controller;
        #gpio-cells = <2>;
    };
    [...]

    data-gpios = <&gpio1 12 0>,
             <&gpio1 13 0>,
             <&gpio1 14 0>,
             <&gpio1 15 0>;

In the above example, &gpio1 uses 2 cells to specify a gpio. The first cell is
a local offset to the GPIO line and the second cell represent consumer flags,
such as if the consumer desire the line to be active low (inverted) or open
drain. This is the recommended practice.

 

 

#define RK_PA0    0       
#define RK_PA1    1      
#define RK_PA2    2       
#define RK_PA3    3       
#define RK_PA4    4       
#define RK_PA5    5       
#define RK_PA6    6       
#define RK_PA7    7       
#define RK_PB0    8       
#define RK_PB1    9       
#define RK_PB2    10       
#define RK_PB3    11       
#define RK_PB4    12       
#define RK_PB5    13       
#define RK_PB6    14       
#define RK_PB7    15       

#define RK_PC0    16       
#define RK_PC1    17       
#define RK_PC2    18       
#define RK_PC3    19       
#define RK_PC4    20       
#define RK_PC5    21       
#define RK_PC6    22       
#define RK_PC7    23       

#define RK_PD0    24       
#define RK_PD1    25       
#define RK_PD2    26       
#define RK_PD3    27       
#define RK_PD4    28       
#define RK_PD5    29       
#define RK_PD6    30       
#define RK_PD7    31       

 

So we can do an shutuo-v8-rk3288 compatible:

Quote

  leds {
        compatible = "gpio-leds";
        status = "okay";

        power-green {
            gpios = <&gpio0 RK_PD3 GPIO_ACTIVE_HIGH>;
            linux,default-trigger = "none";
            default-state = "off";
        };

        power-red {
            gpios = <&gpio0 RK_PD4 GPIO_ACTIVE_HIGH>;
            linux,default-trigger = "none";
            default-state = "off";
        };
    };

    gpio0: gpio@fdd60000 {
            compatible = "rockchip,gpio-bank";
            reg = <0x0 0xfdd60000 0x0 0x100>;
            interrupts = <GIC_SPI 33 IRQ_TYPE_LEVEL_HIGH>;
            clocks = <&pmucru PCLK_GPIO0>, <&pmucru DBCLK_GPIO0>;
            gpio-controller;
            gpio-ranges = <&pinctrl 0 0 32>;
            #gpio-cells = <2>;
            interrupt-controller;
            #interrupt-cells = <2>;
        };

 

many times in mainline you can do some tricks like disabling all usb
