driver-core: remove conditionals around devicetree pointers

2011-01-21T16:24:48Z

Having conditional around the of_match_table and the of_node pointers turns out to make driver code use ugly #ifdef blocks. Drop the conditionals and remove the #ifdef blocks from the affected drivers. Also tidy up minor whitespace issues within the same hunks. Signed-off-by: Grant Likely Acked-by: Greg Kroah-Hartman

ethoc: remove division from loops

2010-11-28T19:16:38Z

Calculating the BD entry using a modulus operation isn't optimal, especially inside the loop. This patch removes the modulus operations in favour of: i) simply checking for wrapping in the case of cur_rx ii) forcing num_tx to be a power of two and using it to mask out the entry from cur_tx The also prevents possible issues related overflow of the cur_rx and cur_tx counters.

ethoc: fix function return type

2010-11-28T19:16:37Z

update_ethoc_tx_stats doesn't need to return anything so make its return type void in order to avoid an unnecessary cast when the function is called. Signed-off-by: Jonas Bonn Signed-off-by: David S. Miller

ethoc: rework mdio read/write

2010-11-28T19:16:37Z

MDIO read and write were checking whether a timeout had expired to determine whether to recheck the result of the MDIO operation. Under heavy CPU usage, however, it was possible for the timeout to expire before the routine got around to be able to check a second time even, thus erroneousy returning an -EBUSY. This patch changes the the MDIO IO routines to try up to five times to complete the operation before giving up, thus lessening the dependency on CPU load. This resolves a problem whereby a ping flood would keep the CPU so busy that the above problem would manifest itself; the MDIO command to check link status would fail and the interface would erroneously be shut down.

ethoc: rework interrupt handling

2010-11-28T19:16:36Z

The old interrupt handling was incorrect in that it did not account for the fact that the interrupt source bits get set irregardless of whether or not their corresponding mask is set. This patch fixes that by masking off the source bits for masked interrupts. Furthermore, the handling of transmission events is moved to the NAPI polling handler alongside the reception handler, thus preventing a whole bunch of interrupts during heavy traffic.

ethoc: Double check pending RX packet

2010-11-28T19:16:36Z

An interrupt may occur between checking bd.stat and clearing the interrupt source register which would result in the packet going totally unnoticed as the interrupt will be missed. Double check bd.stat after clearing the interrupt source register to guard against such an occurrence. Signed-off-by: Jonas Bonn Signed-off-by: David S. Miller

ethoc: enable interrupts after napi_complete

2010-11-28T19:16:35Z

Occasionally, it seems that some race is causing the interrupts to not be reenabled otherwise with the end result that networking just stops working. Enabling interrupts after calling napi_complete is more in line with what other drivers do. Signed-off-by: Jonas Bonn Signed-off-by: David S. Miller

ethoc: Add device tree configuration

2010-11-28T19:16:34Z

This patch adds the ability to describe ethernet devices via a flattened device tree. As device tree remains an optional feature, these bits all need to be guarded by CONFIG_OF ifdefs. MAC address is settable via the device tree parameter "local-mac-address"; however, the selection of the phy id is limited to probing, for now. Signed-off-by: Jonas Bonn Signed-off-by: David S. Miller
