Arch Linux Arm - external RTC problem
#2
if anyone would be interested I managed to make it all work.

- i've modified, recompiled and overwrite to original one (in /boot/dtb) rk3328-rock64.dts, adding this fragment of code

Code:
  &i2c0 {
      status = "okay";
      ds1307: ds1307@68 {
        compatible = "maxim,ds1307";
        reg = <0x68>;
        status = "okay";
      };
      ds3231: ds3231@68 {
        compatible = "maxim,ds3231";
        reg = <0x68>;
        status = "okay";
      };
};

to enable i2c0 bus and to let automatically discovered the rtc device by the kernel at boot time.

- blacklisted rock64 rtc module (rtc_rk808)

- added rtc_ds1307 module to automatic module loading system


After reboot rtc device will be created and the rtc module enabled
