[Xen-users] i2c pass-through in mpsoc

[Jesús Lázaro <jesus.lazaro@xxxxxxx>]

Hi,

I am trying to pass the I2C peripherial in an mpsoc. I have been 
following the example to pass the mac but I keep getting the following 
error:
----
(XEN) XEN_DOMCTL_assign_dt_device: assign "/amba/i2c@ff030000" to dom1 
failed (-22)
libxl: error: libxl_create.c:1424:libxl__add_dtdevs: xc_assign_dtdevice 
failed: -1
libxl: error: libxl_create.c:1461:domcreate_attach_devices: unable to 
add dtdev devices
----

Attached I send the config file as well as the pass-through device tree.

In the main device tree I have modified the I2C to:

i2c@ff030000 {
  compatible = "cdns,i2c-r1p14", "cdns,i2c-r1p10";
  status = "disabled";
  xen,passthrough = "1";
  interrupt-parent = <0x4>;
  interrupts = <0x0 0x12 0x4>;
  reg = <0x0 0xff030000 0x0 0x1000>;
  #address-cells = <0x1>;
  #size-cells = <0x0>;
  power-domains = <0x12>;
  clocks = <0x3 0x3e>;
  clock-frequency = <0x61a80>;
};

Any hints on where the problem is?

Regards,

Jesús
