phy: Change mii_bus id field to a string

2008-04-17T00:09:35+00:00

Having the id field be an int was making more complex bus topologies
excessively difficult.  For now, just convert it to a string, and
change all instances of "bus->id = val" to
snprintf(id, MII_BUS_ID_LEN, "%x", val).

phy/fixed.c: rework to not duplicate PHY layer functionality

2008-01-24T01:33:58+00:00

With that patch fixed.c now fully emulates MDIO bus, thus no need
to duplicate PHY layer functionality. That, in turn, drastically
simplifies the code, and drops down line count.

As an additional bonus, now there is no need to register MDIO bus
for each PHY, all emulated PHYs placed on the platform fixed MDIO bus.
There is also no more need to pre-allocate PHYs via .config option,
this is all now handled dynamically.

PHY fixed driver: rework release path and update phy_id notation

2007-10-10T23:53:50+00:00

device_bind_driver() error code returning has been fixed.  release()
function has been written, so that to free resources in correct way; the
release path is now clean.

Before the rework, it used to cause
 Device 'fixed@100:1' does not have a release() function, it is broken
 and must be fixed.
 BUG: at drivers/base/core.c:104 device_release()

Also changed the notation of the fixed phy definition on
mdio bus to the form of + to make it able to be used by
gianfar and ucc_geth that define phy_id strictly as "%d:%d" and cleaned up
the whitespace issues.

PHY: remove rwsem use from phy core

2007-04-27T17:57:31+00:00

The subsystem rwsem is not used by the driver core at all, so the use of
it in the phy code doesn't make any sense.  They might possibly
want to use a local lock, but I am unsure about that.

[PATCH] remove many unneeded #includes of sched.h

2007-02-14T16:09:54+00:00

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

FS_ENET: OF-related fixup for FEC and SCC MAC's

2007-01-30T14:36:01+00:00

Updated direct resource pass with ioremap call, make it grant proper IRQ
mapping, stuff incompatible with the new approach were respectively put
under #ifndef CONFIG_PPC_MERGE.  It is required so that both ppc and
powerpc could utilize fs_enet effectively.

[PATCH] Slight refactor of interrupt mapping for FSL parts

2006-11-13T03:48:52+00:00

* Cleaned up interrupt mapping a little by adding a helper
  function which parses the irq out of the device-tree, and puts
  it into a resource.
* Changed the arch/ppc platform files to specify PHY_POLL, instead of -1
* Changed the fixed phy to use PHY_IGNORE_INTERRUPT
* Added ethtool.h and mii.h to phy.h includes
