* ucc_geth: Implement suspend/resume and Wake-On-LAN supportAnton Vorontsov2009-08-301-0/+1
| | | | | | | | | | | | | | | This patch implements suspend/resume and WOL support for UCC Ethernet driver. We support two wake up events: wake on PHY/link changes and wake on magic packet. In some CPUs (like MPC8569) QE shuts down during sleep, so magic packet detection is unusable, and also on resume we should fully reinitialize UCC structures.

Also, since we fully construct phy_bus_id in the _probe() routine, we no longer need ->phy_address and ->mdio_bus fields in ucc_geth_info structure. I wish the patch would be a bit shorter, but it seems like the only way to fix the issue in a sane way. Luckily, the patch has been tested with real PHYs and fixed-link, so no further regressions expected.

* ucc_geth: Fix TX watchdog timeout handlingAnton Vorontsov2008-12-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | 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.

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.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | migrate ucc_geth to use the common phylib code. There are several side effects from doing this: o deprecate 'interface' property specification present in some old device tree source files in favour of a split 'max-speed' and 'interface-type' description to appropriately match definitions in include/linux/phy.h. Note that 'interface' property is still honoured if max-speed or interface-type are not present (backward compatible). o compile-time CONFIG_UGETH_HAS_GIGA is eliminated in favour of probe time speed derivation logic. o adjust_link streamlined to only operate on maccfg2 and upsmr.r10m, instead of reapplying static initial values related to the interface-type. o Addition of UEC MDIO of_platform driver requires platform code add 'mdio' type to id list prior to calling of_platform_bus_probe (separate patch). o ucc_struct_init introduced to reduce ucc_geth_startup complexity.

* [PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes ↵Li Yang2006-10-211-125/+123
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and bugfixes changes due to qe_lib changes include: o removed inclusion of platform header file o removed platform_device code, replaced with of_device o removed typedefs o uint -> u32 conversions o removed following defines: QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER, BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET because they hid sizeof/in_be32/out_be32 operations from the reader. o removed irrelevant comments, added others to resemble removed BD_ defines o const'd and uncasted all get_property() assignments bugfixes, courtesy of Scott Wood, include: - Read phy_address as a u32, not u8. - Match on type == "network" as well as compatible == "ucc_geth", as device_is_compatible() will only compare up to the length of the test string, allowing "ucc_geth_phy" to match as well. - fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

* [PATCH] Freescale QE UCC gigabit ethernet driverLi Yang2006-08-191-0/+1339
QE(QUICC Engine) is a new generation communication coprocessor, which can be found on some of the latest Freescale PowerQUICC CPUs(e.g. MPC8360). The UCC(Unified Communications Controller) module of QE can work as gigabit Ethernet device. This patch provides driver for the device.
