[/dev/ttyAML1 and Kernel 5.4.27-meson64]

Hi,

 

I have question about ports /dev/ttyAML1 and /dev/ttyAML2 (device Odroid C2, Image Buster)

I dont see in dmesg the ports /dev/ttyAML1 and /dev/ttyAML2

[    0.000256] printk: console [tty1] enabled
[    1.877506] c81004c0.serial: ttyAML0 at MMIO 0xc81004c0 (irq = 13, base_baud = 1500000) is a meson_uart

How should i chnage the meson-gxbb-odroidc2.dtb to working configuration with kernel 5.4.27-meson64 

This is actual configuration:

            serial@84c0 {
                compatible = "amlogic,meson-gx-uart";
                reg = < 0x00 0x84c0 0x00 0x18 >;
                interrupts = < 0x00 0x1a 0x01 >;
                status = "disabled";
                clocks = < 0x0e 0x03 0x1a 0x0e >;
                clock-names = "xtal\0pclk\0baud";
                pinctrl-0 = < 0x0f >;
                pinctrl-names = "default";
                phandle = < 0x47 >;
            };

 

With kernel 4.19.69 was working with following change in meson-gxbb-odroidc2.dtb

            serial@84c0 {
                compatible = "amlogic,meson-gx-uart";
                reg = < 0x00 0x84c0 0x00 0x18 >;
                interrupts = < 0x00 0x1a 0x01 >;
                status = "disabled";
                clocks = < 0x0d 0x0b 0x1a 0x0d >;
                clock-names = "xtal\0pclk\0baud";
                pinctrl-names = "default";
                pinctrl-0 = < 0x72 >;
                phandle = < 0x43 >;
            };

 

Thanks for help
