* netdevice: safe convert to netdev_priv() #part-2Wang Chen2008-11-13
| | | | | | | | | | | | | | | | | | We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. This patch is a safe convert for netdev->priv to netdev_priv(netdev). Since all of the netdev->priv is only for read. But it is too big to be sent in one mail. I split it to 4 parts and make every part smaller than 100,000 bytes, which is max size allowed by vger.

* net: convert print_mac to %pMJohannes Berg2008-10-27
| | | | | | | | | | | | This converts pretty much everything to print_mac. There were a few things that had conflicts which I have just dropped for now, no harm done. I've built an allyesconfig with this and looked at the files that weren't built very carefully, but it's a huge patch. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: David S.

* dm9000: Support MAC address setting through platform data.Laurent Pinchart2008-08-07
| | | | | | | | | | | | 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 DEFAULT_TRIGGER for request_irq() flags.Ben Dooks2008-06-24
| | | | | | | | | | | 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: Allow the use of the NSR register to get link status.Ben Dooks2008-06-24
| | | | | | | | | | | | | 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 PHYBen Dooks2008-06-24
| | | | | | | | | | 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. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| | | | | | | | | | | 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.

| | | | | | | | | | Add support for both the DM9000A and DM9000B versions of the DM9000 networking chip.

* DM9000: Remove the 2 resources probe scheme.Laurent Pinchart2008-06-24
| | | | | | | | | | | 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.

* net drivers: fix platform driver hotplug/coldplugKay Sievers2008-04-25
| | | | | | | | | | | | | | | | | | | | | | | | | | Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable network platform drivers, to re-enable auto loading. NOTE: didn't change drivers/net/fs_enet/fs_enet-main.c "old binding" support. That looks problematic in the first place (it even uses the ancient "struct device_driver" binding scheme for platform_bus!) and I suspect it will vanish soonish when arch/powerpc rules the world. Also, drivers/net/ne.c would have needed more thought to sort out.

| | | | | | | | | | | | | Reading the ID register does not always return the correct ID from the device, so we retry several times to see if we get a correct value.

* DM9000: Remove barely used SROM array read.Ben Dooks2008-02-11
| | | | | | | | | | | | | | | The srom array in the board data is only being used in the device probe routines. The probe also only uses the first 6 bytes of an array we spend 512ms reading 128 bytes from. Change to reading the MAC area directly to the MAC address structure. As a side product, we rename the read_srom_word to dm9000_read_eeprom to bring it into line with the rest of the driver. No change is made to the delay in this function, which will be dealt with in a later patch. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* DM9000: Use msleep() instead of udelay()Ben Dooks2008-02-11
| | | | | | | | | | | | We can use sleeping functions when reading and writing the PHY registers, so let us sleep instead of busy waiting for the PHY.

* DM9000: Do not sleep with spinlock and IRQs heldBen Dooks2008-02-11
| | | | | | | | | | | | | | The phy read and write routines call udelay() with the board lock held, and with the posibility of IRQs being disabled. Since these delays can be up to 500usec, and are only required as we have to save the chip's address register. To improve the behaviour, hold the lock whilst we are writing and then restore the state before the delay and then repeat the process once the delay has happened.

* DM9000: Remove old timer based poll routinesBen Dooks2008-02-11
| | | | | | | | | | | | | | | | | | | Remove the timer based MII phy polling, as this is currently broken with the new EEPROM code that now uses mutexes to protect the phy access. This will need to be replaced in the future by some form of mutex safe mechanism for reading the MII phy status. The replacement has not been done here as changing this patch, which is early in the sequence has quite a knock-on effect. Once this series is merged, then a new presentation of an patch to poll the MII link status can be added. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* DM9000: Pass IRQ flags via platform resourcesBen Dooks2008-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | Use the flags in the IRQ resource to specify the type of IRQ being requested, so that systems which do not have level-based interrupts, or change the interrupt in some other way can specify this without making an #ifdef mess in the driver. This is specifically designed to undo the change in commit 4e4fc05a2b6e7bd2e0facd96e0c18dceb34d9349 which hardwires the type for everyone but blackfin to IRQT_RISING, which breaks all a number of Simtec boards which use (and setup in the bootloader) active low IRQs. Note, although there where originally objections due to the use of IORESOURCE_IRQ and IRQT_ flags not sharing the same definition, at least <include/linux/interrupt.h> notes these are the same.
