DM9000 Network driver | ||
===================== | ||
|
||
Copyright 2008 Simtec Electronics, | ||
Ben Dooks <[email protected]> <[email protected]> | ||
|
||
|
||
Introduction | ||
------------ | ||
|
||
This file describes how to use the DM9000 platform-device based network driver | ||
that is contained in the files drivers/net/dm9000.c and drivers/net/dm9000.h. | ||
|
||
The driver supports three DM9000 variants, the DM9000E which is the first chip | ||
supported as well as the newer DM9000A and DM9000B devices. It is currently | ||
maintained and tested by Ben Dooks, who should be CC: to any patches for this | ||
driver. | ||
|
||
|
||
Defining the platform device | ||
---------------------------- | ||
|
||
The minimum set of resources attached to the platform device are as follows: | ||
|
||
1) The physical address of the address register | ||
2) The physical address of the data register | ||
3) The IRQ line the device's interrupt pin is connected to. | ||
|
||
These resources should be specified in that order, as the ordering of the | ||
two address regions is important (the driver expects these to be address | ||
and then data). | ||
|
||
An example from arch/arm/mach-s3c2410/mach-bast.c is: | ||
|
||
static struct resource bast_dm9k_resource[] = { | ||
[0] = { | ||
.start = S3C2410_CS5 + BAST_PA_DM9000, | ||
.end = S3C2410_CS5 + BAST_PA_DM9000 + 3, | ||
.flags = IORESOURCE_MEM, | ||
}, | ||
[1] = { | ||
.start = S3C2410_CS5 + BAST_PA_DM9000 + 0x40, | ||
.end = S3C2410_CS5 + BAST_PA_DM9000 + 0x40 + 0x3f, | ||
.flags = IORESOURCE_MEM, | ||
}, | ||
[2] = { | ||
.start = IRQ_DM9000, | ||
.end = IRQ_DM9000, | ||
.flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHLEVEL, | ||
} | ||
}; | ||
|
||
static struct platform_device bast_device_dm9k = { | ||
.name = "dm9000", | ||
.id = 0, | ||
.num_resources = ARRAY_SIZE(bast_dm9k_resource), | ||
.resource = bast_dm9k_resource, | ||
}; | ||
|
||
Note the setting of the IRQ trigger flag in bast_dm9k_resource[2].flags, | ||
as this will generate a warning if it is not present. The trigger from | ||
the flags field will be passed to request_irq() when registering the IRQ | ||
handler to ensure that the IRQ is setup correctly. | ||
|
||
This shows a typical platform device, without the optional configuration | ||
platform data supplied. The next example uses the same resources, but adds | ||
the optional platform data to pass extra configuration data: | ||
|
||
static struct dm9000_plat_data bast_dm9k_platdata = { | ||
.flags = DM9000_PLATF_16BITONLY, | ||
}; | ||
|
||
static struct platform_device bast_device_dm9k = { | ||
.name = "dm9000", | ||
.id = 0, | ||
.num_resources = ARRAY_SIZE(bast_dm9k_resource), | ||
.resource = bast_dm9k_resource, | ||
.dev = { | ||
.platform_data = &bast_dm9k_platdata, | ||
} | ||
}; | ||
|
||
The platform data is defined in include/linux/dm9000.h and described below. | ||
|
||
|
||
Platform data | ||
------------- | ||
|
||
Extra platform data for the DM9000 can describe the IO bus width to the | ||
device, whether or not an external PHY is attached to the device and | ||
the availability of an external configuration EEPROM. | ||
|
||
The flags for the platform data .flags field are as follows: | ||
|
||
DM9000_PLATF_8BITONLY | ||
|
||
The IO should be done with 8bit operations. | ||
|
||
DM9000_PLATF_16BITONLY | ||
|
||
The IO should be done with 16bit operations. | ||
|
||
DM9000_PLATF_32BITONLY | ||
|
||
The IO should be done with 32bit operations. | ||
|
||
DM9000_PLATF_EXT_PHY | ||
|
||
The chip is connected to an external PHY. | ||
|
||
DM9000_PLATF_NO_EEPROM | ||
|
||
This can be used to signify that the board does not have an | ||
EEPROM, or that the EEPROM should be hidden from the user. | ||
|
||
DM9000_PLATF_SIMPLE_PHY | ||
|
||
Switch to using the simpler PHY polling method which does not | ||
try and read the MII PHY state regularly. This is only available | ||
when using the internal PHY. See the section on link state polling | ||
for more information. | ||
|
||
The config symbol DM9000_FORCE_SIMPLE_PHY_POLL, Kconfig entry | ||
"Force simple NSR based PHY polling" allows this flag to be | ||
forced on at build time. | ||
|
||
|
||
PHY Link state polling | ||
---------------------- | ||
|
||
The driver keeps track of the link state and informs the network core | ||
about link (carrier) availablilty. This is managed by several methods | ||
depending on the version of the chip and on which PHY is being used. | ||
|
||
For the internal PHY, the original (and currently default) method is | ||
to read the MII state, either when the status changes if we have the | ||
necessary interrupt support in the chip or every two seconds via a | ||
periodic timer. | ||
|
||
To reduce the overhead for the internal PHY, there is now the option | ||
of using the DM9000_FORCE_SIMPLE_PHY_POLL config, or DM9000_PLATF_SIMPLE_PHY | ||
platform data option to read the summary information without the | ||
expensive MII accesses. This method is faster, but does not print | ||
as much information. | ||
|
||
When using an external PHY, the driver currently has to poll the MII | ||
link status as there is no method for getting an interrupt on link change. | ||
|
||
|
||
DM9000A / DM9000B | ||
----------------- | ||
|
||
These chips are functionally similar to the DM9000E and are supported easily | ||
by the same driver. The features are: | ||
|
||
1) Interrupt on internal PHY state change. This means that the periodic | ||
polling of the PHY status may be disabled on these devices when using | ||
the internal PHY. | ||
|
||
2) TCP/UDP checksum offloading, which the driver does not currently support. | ||
|
||
|
||
ethtool | ||
------- | ||
|
||
The driver supports the ethtool interface for access to the driver | ||
state information, the PHY state and the EEPROM. |
