smc911x: how to call the driver?

smc911x: how to call the driver?

[Jens Gehrlein]

Hi,

on our board a SMSC LAN9215i is connected to an i.MX31 ARM processor. My 
hope is to get the smc911x driver run on this chip. The LAN921x data 
sheets say that existing 911x drivers should work.

The first I had to patch was the Kconfig file, in which the smc911x 
driver is only available on PXA architecture:
- depends on NET_ETHERNET && ARCH_PXA
+ depends on NET_ETHERNET && (ARCH_PXA || ARCH_MXC)
So the driver got at least compiled.

My next problem is:
Where and when get the functions smc911x_drv_probe() and smc911x_init() 
called? Any hints?

Thank you in advance.

Best Regards,
Jens

Why are you asking this in a powerpc list?

You need to register a struct platform_device in your platform code,
E.G. something like:

static struct resource smc911x_resources[] = {
        [0] = {
                .start  = 0x8e000000,
                .end    = 0x8e0000ff,
                .flags  = IORESOURCE_MEM,
        },
        [1] = {
                .start  = 4,
                .end    = 4,
                .flags  = IORESOURCE_IRQ,
        },
};

static struct platform_device thinlite_eth = {
        .name                   = "smc911x",
        .id                     = 0,
        .num_resources          = ARRAY_SIZE(smc911x_resources),
        .resource               = smc911x_resources,
};

And then do a platform_add_devices with it.

Hi Peter,

thank you for responding.

Uuh, sorry. In the haste I just read "embedded". Actually, my question 
isn't processor related. Rather it's (network) device driver related.
Could you recommend a mailing list for this?

Mmmh, this is all new to me. I'll try to get through it and perhaps 
we'll meet on the other mailinglist again.

Thank you very much so far.
