2007-04-28phy layer: add kernel-doc + DocBookRandy Dunlap

2007-04-27PHY: remove rwsem use from phy coreGreg Kroah-Hartman
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. Cc: netdev <netdev@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
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).

2006-12-13[PATCH] Fix numerous kcalloc() calls, convert to kzalloc()Robert P. J. Day
All kcalloc() calls of the form "kcalloc(1,...)" are converted to the equivalent kzalloc() calls, and a few kcalloc() calls with the incorrect ordering of the first two arguments are fixed.

2006-12-02[PATCH] PHY: Add support for configuring the PHY connection interfaceAndy Fleming
Most PHYs connect to an ethernet controller over a GMII or MII interface. However, a growing number are connected over different interfaces, such as RGMII or SGMII. The ethernet driver will tell the PHY what type of connection it is by setting it manually, or passing it in through phy_connect (or phy_attach). Changes include: * Updates to documentation * Updates to PHY Lib consumers * Changes to PHY Lib to add interface support * Some minor changes to whitespace in phy.h * gianfar driver now detects interface and passes appropriate value to PHY Lib Signed-off-by: Andrew Fleming <afleming@freescale.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-12-02[PATCH] Fixed a number of bugs in the PHY LayerAndy Fleming
* genphy_update_link is now exported * Added a fix from ncase@xes-inc.com which changes forcing so it only updates the link. Otherwise, it never tries the lower values, since it is always overwriting the speed/duplex values with the current ones, rather than the intended ones. * Fixed a bug where bringing up a PHY with no link caused it to timeout, and enter forcing mode. Once in forcing mode, plugging in the link didn't autonegotiate. Now the AN state detects the lack of link, and enters the NO_LINK state. AN only times out if the link is up and AN fails * Cleaned up the PHY_AN case, reducing one level of indentation for the timeout code. Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-09-25[PATCH] Signedness issue in drivers/net/phy/phy_device.cEric Sesterhenn
While checking gcc 4.1 -Wextra warnings, I stumbled across the following two warnings: drivers/net/phy/phy_device.c:528: warning: comparison of unsigned expression < 0 is always false drivers/net/phy/phy_device.c:546: warning: comparison of unsigned expression < 0 is always false Since phy_read() returns an integer and can return negative values, it seems to me the best way to get proper error handling working again is to make val an int. Currently it is an u32, so the < 0 check always fails.
