2009-01-29ucc_geth: Change uec phy id to the same format as gianfar'sHaiying Wang1-2/+18
The commit b31a1d8b41513b96e9c7ec2f68c5734cef0b26a4 ("gianfar: Convert gianfar to an of_platform_driver") changes the gianfar's phy id to the format like "mdio@xxxx:xx", but uec still uses the old format like "xxxxxxxx:xx". For the board whose UEC uses gianfar-mdio like MPC8568MDS, the phy can not be attached because of the incompatible phy id format. This patch changes uec's phy id to the same format as gianfar's.

2009-01-11ucc_geth: use correct UCCE macrosTimur Tabi1-85/+43
The UCC Event Register (UCCE) already has unambigous macro definitions in qe.h, so we should not be defining our own in the UCC Ethernet driver. Removed unused local variable 'dev' from ucc_geth_poll(), which fixes a warning caused by commit 908a7a16b852ffd618a9127be8d62432182d81b4 ("net: Remove unused netdev arg from some NAPI interfaces.").

2008-12-18ucc_geth: Cleanup repetitive ucc_geth_memclean() callsAnton Vorontsov1-30/+1

2008-12-18ucc_geth: Fix IRQ freeing code in ucc_geth_open()Anton Vorontsov1-9/+8
open() routine calls stop() in case of errors, the function will try to free the requested IRQ. But we don't know if it was actually requested, so the code might issue bogus free_irq(0, dev) call. Fix this by rearranging the code so that now request_irq() is the last call in the open() routine, and move free_irq() into the close().

2008-12-18ucc_geth: Fix TX watchdog timeout handlingAnton Vorontsov1-8/+29
The timeout handling code is currently broken in several ways: - It calls stop() (which frees all the memory and IRQ), and then calls startup() (which won't re-request IRQ, neither it will re-init the Fast UCC structure). - It calls these routines from the softirq context, which is wrong, since stop() calls free_irq() (which might sleep) and startup() allocates things with GFP_KERNEL. - It won't soft-reset the PHY. We need the PHY reset for at least MPC8360E-MDS boards with Marvell 88E1111 PHY, the PHY won't recover from timeouts w/o the reset. So the patch fixes these problems by implementing the workqueue for the timeout handling, and there we fully re-open the device via close() and open() calls. The close/open paths do the right things, and I can see that the driver actually survive the timeouts. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-18ucc_geth: Fix endless loop in stop_{tx,rx} routinesAnton Vorontsov1-3/+6
Currently the routines wait for the various bits w/o an assumption that bits may never get set. When timeouts happen I see that these bits never get set and so the routines hang the kernel. With this patch we'll wait the graceful stop for 100 ms, and then will simply exit. There is nothing* we can do about that, but it's OK since we'll do full reset later. * Well, actually, there is also not-graceful variant for the TX stop, but specs says that we never should use it.

2007-10-10[NET]: Nuke SET_MODULE_OWNER macro.Ralf Baechle1-1/+0
It's been a useless no-op for long enough in 2.6 so I figured it's time to remove it. The number of people that could object because they're maintaining unified 2.4 and 2.6 drivers is probably rather small.

2007-10-10[NET]: Make NAPI polling independent of struct net_device objects.Stephen Hemminger1-31/+33
Several devices have multiple independant RX queues per net device, and some have a single interrupt doorbell for several queues. In either case, it's easier to support layouts like that if the structure representing the poll is independant from the net device itself. The signature of the ->poll() call back goes from: int foo_poll(struct net_device *dev, int *budget) to int foo_poll(struct napi_struct *napi, int budget) The caller is returned the number of RX packets processed (or the number of "NAPI credits" consumed if you want to get abstract). The callee no longer messes around bumping dev->quota, *budget, etc. because that is all handled in the caller upon return. The napi_struct is to be embedded in the device driver private data structures. Furthermore, it is the driver's responsibility to disable all NAPI instances in it's ->stop() device close handler. Since the napi_struct is privatized into the driver's private data structures, only the driver knows how to get at all of the napi_struct instances it may have per-device. With lots of help and suggestions from Rusty Russell, Roland Dreier, Michael Chan, Jeff Garzik, and Jamal Hadi Salim. Bug fixes from Thomas Graf, Roland Dreier, Peter Zijlstra, Joseph Fannin, Scott Wood, Hans J. Koch, and Michael Chan. [ Ported to current tree and all drivers converted. Integrated Stephen's follow-on kerneldoc additions, and restored poll_list handling to the old style to fix mutual exclusion issues. -DaveM ] Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S.

2007-10-08[POWERPC] qe: miscellaneous code improvements and fixes to the QE libraryTimur Tabi1-1/+1
This patch makes numerous miscellaneous code improvements to the QE library. 1. Remove struct ucc_common and merge ucc_init_guemr() into ucc_set_type() (every caller of ucc_init_guemr() also calls ucc_set_type()). Modify all callers of ucc_set_type() accordingly. 2. Remove the unused enum ucc_pram_initial_offset. 3. Refactor qe_setbrg(), also implement work-around for errata QE_General4. 4. Several printk() calls were missing the terminating \n. 5. Add __iomem where needed, and change u16 to __be16 and u32 to __be32 where appropriate. 6. In ucc_slow_init() the RBASE and TBASE registers in the PRAM were programmed with the wrong value. 7. Add the protocol type to struct us_info and updated ucc_slow_init() to use it, instead of always programming QE_CR_PROTOCOL_UNSPECIFIED. 8. Rename ucc_slow_restart_x() to ucc_slow_restart_tx() 9. Add several macros in qe.h (mostly for slow UCC support, but also to standardize some naming convention) and remove several unused macros. 10. Update ucc_geth.c to use the new macros. 11. Add ucc_slow_info.protocol to specify which QE_CR_PROTOCOL_xxx protcol to use when initializing the UCC in ucc_slow_init(). 12. Rename ucc_slow_pram.rfcr to rbmr and ucc_slow_pram.tfcr to tbmr, since these are the real names of the registers. 13. Use the setbits, clrbits, and clrsetbits where appropriate. 14. Refactor ucc_set_qe_mux_rxtx(). 15. Remove all instances of 'volatile'. 16. Simplify get_cmxucr_reg(); 17. Replace qe_mux.cmxucrX with qe_mux.cmxucr[]. 18. Updated struct ucc_geth because struct ucc_fast is not padded any more. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-09-15ucc_geth: fix compilationAnton Vorontsov1-1/+1
Currently qe_bd_t is used in the macro call -- dma_unmap_single, which is a no-op on PPC32, thus error is hidden today. Starting with 2.6.24, macro will be replaced by the empty static function, and erroneous use of qe_bd_t will trigger compilation error.

2007-05-15ucc_geth: eliminate max-speed, change interface-type to phy-connection-typeKim Phillips1-24/+16
It was agreed that phy-connection-type was a better name for the interface-type property, so this patch renames it. Also, the max-speed property name was determined too generic, and is therefore eliminated in favour of phy-connection-type derivation logic. includes corrections to copyright text.
