[patch 0/9] DM9000 updates for 2.6.27

[patch 0/9] DM9000 updates for 2.6.27

[Ben Dooks]

This set of updates adds support for the newer DM9000
compatible devices (DM9000A and DM9000B) and support
for faster link-status polling. It also has some source
cleanups and misc fixes.

I've included the DM9000 only part of Laurent's resource
fixes and a few tidyups resulting from these changes.

[patch 1/9] DM9000: Remove the 2 resources probe scheme.

[Ben Dooks]

[-- Attachment #1: thirdparty/dm9000-remove-2resources.patch --]
[-- Type: text/plain, Size: 4431 bytes --]

From: Laurent Pinchart <laurentp@cse-semaphore.com>

The dm9000 driver accepts either 2 or 3 resources to describe the platform
devices. The 2 resources case abuses the ioresource mechanism by passing
ioremap()ed memory through the platform device resources. This patch removes
that case and converts boards that were using it to the 3 resources scheme.

[patch 2/9] DM9000: Add support for DM9000A and DM9000B chips

[Ben Dooks]

[-- Attachment #1: simtec/simtec-drivers-net-dm9000-support-dm9000ab.patch --]
[-- Type: text/plain, Size: 4974 bytes --]

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.

[patch 4/9] DM9000: Cleanup source code - remove forward declerations

[Ben Dooks]

[-- Attachment #1: simtec/simtec-drivers-net-dm9000-cleanups2.patch --]
[-- Type: text/plain, Size: 32590 bytes --]

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

[patch 5/9] DM9000: Use NSR to determine link-status on internal PHY

[Ben Dooks]

[-- Attachment #1: simtec/simtec-drivers-net-dm9000-linkstatus1.patch --]
[-- Type: text/plain, Size: 1055 bytes --]

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.

[patch 6/9] DM9000: Allow the use of the NSR register to get link status.

[Ben Dooks]

[-- Attachment #1: simtec/simtec-drivers-net-dm9000-linkstatus2.patch --]
[-- Type: text/plain, Size: 2709 bytes --]

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.

Argh, this didn't get refreshed before emailing the quilt, will
fix and re-send with the blackfin updates
