| * drivers/net: ks8842 Fix crash on received packet when in PIO mode.Dennis Aberilla2011-05-311-1/+1
| | | | | | | | | | | | | | | | | | This patch fixes a driver crash during packet reception due to not enough bytes allocated in the skb. Since the loop reads out 4 bytes at a time, we need to allow for up to 3 bytes of slack space. Signed-off-by: Dennis Aberilla <denzzzhome@yahoo.com> Signed-off-by: David S.

* | mfd: Use mfd cell platform_data for timberdale cells platform bitsSamuel Ortiz2011-05-261-2/+1
|/ | | | | | | | | | | With the addition of a device platform mfd_cell pointer, MFD drivers can go back to passing platform data back to their sub drivers. This allows for an mfd_cell->mfd_data removal and thus keep the sub drivers MFD agnostic. This is mostly needed for non MFD aware sub drivers.

* mfd: mfd_cell is now implicitly available to timberdale driversAndres Salomon2011-03-231-1/+2
| | | | | | | | | | | | The cell's platform_data is now accessed with a helper function; change clients to use that, and remove the now-unused data_size. Note that the mfd's platform_data is marked __devinitdata. This is still correct in all cases except for the timbgpio driver, whose remove hook has been changed to no longer reference the pdata.

* ks8842: Support DMA when accessed via timberdaleRichard Röjfors2010-07-271-21/+443
| | | | | | | | | | | | | | | | | | | | | This patch adds support for RX and TX DMA via the DMA API, this is only supported when the KS8842 is accessed via timberdale. There is no support for DMA on the generic bus interface it self, a state machine inside the FPGA is handling RX and TX transfers to/from buffers in the FPGA. The host CPU can do DMA to and from these buffers. The FPGA has to handle the RX interrupts, so these must be enabled in the ks8842 but not in the FPGA. The driver must not disable the RX interrupt that would mean that the data transfers into the FPGA buffers would stop. The host shall not enable TX interrupts since TX is handled by the FPGA, the host is notified by DMA callbacks when transfers are finished. Which DMA channels to use are added as parameters in the platform data struct. Signed-off-by: Richard Röjfors <richard.rojfors@pelagicore.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* ks8842: Support 100Mbps when accessed via timberdaleRichard Röjfors2010-07-261-5/+10
| | | | | | | | | | | | This patch removes the code which disables 100Mbps advertising when the ks8842 is accessed via timberdale. At higher speed it's good to be nice to the internal state machine of timberdale by acking interrupts. That is done by a write to the interrupt ack register (IAR).

* ks8842: Do the TX timeout work in workqueue context.Richard Röjfors2010-07-081-2/+22
| | | | | | | | | | | Currently all code that needs to be run at TX timeout is done in the calling context, where bottom halves are disabled. Some of the code blocks, so it needs to be done in a different context. This patch adds in a work struct which is scheduled at TX timeout. Then the timeout code is executed within work queue context.

| | | | | | | | | | | | | This patch adds platform data to the ks8842 driver. Via the platform data a MAC address, to be used by the controller, can be passed.
