net: phy: adjust fixed_phy_register() return value

2014-10-07T17:06:45Z

Adjust fixed_phy_register() to return struct phy_device *, so that it becomes easy to use fixed PHYs without device tree support: phydev = fixed_phy_register(PHY_POLL, &fixed_phy_status, NULL); fixed_phy_set_link_update(phydev, fixed_phy_link_update); phy_connect_direct(netdev, phydev, handler_fn, phy_interface); This change is a prerequisite for modifying bcmgenet driver to work without a device tree on Broadcom's MIPS-based 7xxx platforms.

net: phy: fixed: return an error for Clause 45 over 22 reads

2014-08-23T18:39:09Z

The fixed PHY driver does not properly emulate Clause 45 over Clause 22 MDIO reads, and as such, will return bogus values when we access such registers. Return an error when accessing these registers in order to prevent advertising bogus capabilities such as EEE support and such. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: extend fixed driver with fixed_phy_register()

2014-05-16T21:18:49Z

The existing fixed_phy_add() function has several drawbacks that prevents it from being used as is for OF-based declaration of fixed PHYs: * The address of the PHY on the fake bus needs to be passed, while a dynamic allocation is desired. * Since the phy_device instantiation is post-poned until the next mdiobus scan, there is no way to associate the fixed PHY with its OF node, which later prevents of_phy_connect() from finding this fixed PHY from a given OF node. To solve this, this commit introduces fixed_phy_register(), which will allocate an available PHY address, add the PHY using fixed_phy_add() and instantiate the phy_device structure associated with the provided OF node.

net: phy: decouple PHY id and PHY address in fixed PHY driver

2014-05-16T21:18:48Z

Until now, the fixed_phy_add() function was taking as argument 'phy_id', which was used both as the PHY address on the fake fixed MDIO bus, and as the PHY id, as available in the MII_PHYSID1 and MII_PHYSID2 registers. However, those two informations are completely unrelated. This patch decouples them. The PHY id of fixed PHYs is hardcoded to be 0x0. Ideally, a really reserved value would be nicer, but there doesn't seem to be an easy of making sure a dummy value can be assigned to the Linux kernel for such usage. The PHY address remains passed by the caller of phy_fixed_add(). Signed-off-by: Thomas Petazzoni Reviewed-by: Florian Fainelli Tested-by: Florian Fainelli Signed-off-by: David S. Miller

phy: Use pr_

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h

2010-03-30T13:02:32Z

percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

phylib: two dynamic mii_bus allocation fallout fixes

2008-10-09T16:45:04Z

1. arch/powerpc/platforms/pasemi/gpio_mdio.c also needs to be converted over to mdiobus_{alloc,free}(). 2. drivers/net/phy/fixed.c used to embed a struct mii_bus into its struct fixed_mdio_bus and then use container_of() to go from the former to the latter. Since mii bus structures are no longer embedded, we need to do something like use the mii bus private pointer to go from mii_bus to fixed_mdio_bus instead.
