pnp_enable_resource not being called

In the AMD8111_lpc.c
static void amd8111_lpc_enable_resources(device_t dev)
{
pci_dev_enable_resources(dev);
enable_childrens_resources(dev);
}
static struct device_operations lpc_ops = {
.read_resources = amd8111_lpc_read_resources,
.set_resources = pci_dev_set_resources,
.enable_resources = amd8111_lpc_enable_resources,
.init = lpc_init,
.scan_bus = scan_static_bus,
// .enable = amd8111_enable,
.ops_pci = &lops_pci,
};
So I guess you need to add the device driver for the lpc in SB.
Then the scan_static_bus and enable_childrens_resources(dev) will be called.

The sandpoint has the following structure:
Northbridge MPC107 --> Southbridge W83C553 --> Superio PC97307
The config file looks like:
chip northbridge/motorola/mpc107
device pci_domain 0 on
device pci 0.0 on end
device pci b.0 on
chip southbridge/winbond/w83c553
chip superio/NSC/pc97307
device pnp 15c.0 on end #
Kyeboard
device pnp 15c.1 on end # Mouse
device pnp 15c.2 on end #
Real-time Cloc
k
device pnp 15c.3 on end # Floppy
device pnp 15c.4 on end #
Parallel port
device pnp 15c.5 on end # com2
device pnp 15c.6 on end # com1
device pnp 15c.7 on end # gpio
device pnp 15c.8 on end # Power
manageme
nt
end
end
end # pci to isa bridge
device pci b.1 on end # pci ide controller
end
device cpu_bus 0 on
chip cpu/ppc/mpc74xx
device cpu 0 on end
end
end
end
The dev_enumerate() code is calling the PNP enable routines and the
dev_initialize() code is calling the PNP init routine. However the
dev_enable() code never calls the PNP enable_resource routine, which
means the the PNP devices are never actually enabled.
The enable_dev routine for the superio device calls:
pnp_enable_devices(dev, &ops,
sizeof(pnp_dev_info)/sizeof(pnp_dev_info[0]),
pnp_dev_info);
where ops is defined as:
static struct device_operations ops = {
.read_resources = pnp_read_resources,
.set_resources = pnp_set_resources,
.enable_resources = pnp_enable_resources,
.enable = pnp_enable,
.init = init,
};
Any ideas why this is not working? Is there something else that needs
to happen?
