dm9000: Support MAC address setting through platform data.

2008-08-07T06:22:54+00:00

The dm9000 driver reads the chip's MAC address from the attached EEPROM. When
no EEPROM is present, or when the MAC address is invalid, it falls back to
reading the address from the chip.

This patch lets platform code set the desired MAC address through platform
data.

DM9000: Remove magic numbers

2008-07-22T21:54:07+00:00

Remove magic numbers for items that we already have
defined in the register header file.

DM9000: Remove DEFAULT_TRIGGER for request_irq() flags.

2008-06-25T02:58:36+00:00

Currently all but one user (AT91SAM9261EK) of the dm9000
driver passes their IRQ flags through the resources attached
to the platform device. This means we can remove the use
of DEFAULT_TRIGGER as the blackfin machines all seem to
have their triggers set properly.

DM9000: Add missing msleep() in EEPROM wait code.

2008-06-25T02:58:17+00:00

The msleep() call in the code that checks for the
EEPROM controller's busy status was missing.

DM9000: Allow the use of the NSR register to get link status.

2008-06-25T02:58:07+00:00

The DM9000's internal PHY reports a copy of the link status
in the NSR register of the chip. Reading the status when
polling for link status is faster as it eliminates the need
to sleep, but does not print as much information.

Add an platform flag to force this behaviour, and a Kconfig
option to allow it to be forced to the faster method always.

DM9000: Use NSR to determine link-status on internal PHY

2008-06-25T02:57:58+00:00

The DM9000_NSR register contains a copy of the internal PHY's
link status which we can use to determine if the link is up
or down. This eliminates the more costly (and sleeping) PHY
read when using the DM9000's own PHY.

DM9000: Cleanup source code - remove forward declerations

2008-06-25T02:57:51+00:00

Cleanup the source code by moving the code around to avoid
having to declare the functions before they are used.

DM9000: Cleanup source code

2008-06-25T02:57:42+00:00

Cleanup bits of the DM9000 driver to make the code
neater and easier to read. This is includes removing
some old definitions, re-indenting areas, etc.

DM9000: Cleanups after the resource changes

2008-06-25T02:57:28+00:00

Remove the now extraneous checks in dm9000_release_board()
now that the two-resource case is removed. Also remove the
check on pdev->num_resources, as we check the return data
from platform_get_resource() to ensure we have not only
the right number but the right type of resources as well.

DM9000: Add support for DM9000A and DM9000B chips

2008-06-25T02:57:16+00:00

Add support for both the DM9000A and DM9000B versions of
the DM9000 networking chip. This includes adding support
for the Link-Change IRQ which is used instead of polling
the PHY every 2 seconds.
