Hello, I have spend a lot of time trying to make it work I2C PL0/PL1 of orangepi zero plus 2 H5.

 

I change sunxi-h3-h5.dtsi to status="okay" and i can not to see i2c PL0/PL1 only I can see others i2c. Can anybody help me to understand what I am doing bad?

    r_i2c: i2c@1f02400 {
            compatible = "allwinner,sun6i-a31-i2c";
            reg = <0x01f02400 0x400>;
            interrupts = <GIC_SPI 44 IRQ_TYPE_LEVEL_HIGH>;
            pinctrl-names = "default";
            pinctrl-0 = <&r_i2c_pins>;
            clocks = <&r_ccu CLK_APB0_I2C>;
            resets = <&r_ccu RST_APB0_I2C>;
            status = "okay";
            #address-cells = <1>;
            #size-cells = <0>;
        };

r_pio: pinctrl@1f02c00 {
            compatible = "allwinner,sun8i-h3-r-pinctrl";
            reg = <0x01f02c00 0x400>;
            interrupts = <GIC_SPI 45 IRQ_TYPE_LEVEL_HIGH>;
            clocks = <&r_ccu CLK_APB0_PIO>, <&osc24M>, <&rtc 0>;
            clock-names = "apb", "hosc", "losc";
            gpio-controller;
            #gpio-cells = <3>;
            interrupt-controller;
            #interrupt-cells = <3>;

            r_ir_rx_pin: r-ir-rx-pin {
                pins = "PL11";
                function = "s_cir_rx";
            };

            r_i2c_pins: r-i2c-pins {
                pins = "PL0", "PL1";
                function = "s_i2c";
            };
        };

I gave it a try and I got /dev/i2c-2 added to my previous setup, although I didn't plug any devices on it yet ...

root@orangepizeroplus2:~# i2cdetect -l
i2c-1	i2c       	DesignWare HDMI                 	I2C adapter
i2c-2	i2c       	mv64xxx_i2c adapter             	I2C adapter
i2c-0	i2c       	mv64xxx_i2c adapter             	I2C adapter

 

 

Thanks martinayotte.

 

I try to see i2c-1 but nothing is shown even when I change connections between i2c ports (0<>1). May be it's a problem related to pinmux?. Thanks for your help
