Subject: [GIT *] Solos PCI ADSL card update
Please pull from git://git.infradead.org/~dwmw2/solos-2.6.git
This contains a bunch of updates to the Solos PCI driver (full patch
below for review):
David Woodhouse (27):
solos: Fix length header in FPGA transfers
solos: Clean up firmware loading code
solos: Kill global 'opens' count.
solos: Handle attribute show/store in kernel more sanely
solos: Add initial list of parameters
solos: Handle new line status change packets, hook up to ATM layer info
solos: Kill existing connections on link down event
solos: Reject non-AAL5 connections.... for now
solos: Add SNR and Attn to status packet, fix oops on load
solos: Fix under-allocation of skb size for get/set parameters
solos: Remove parameter group from sysfs on ATM dev deregister
solos: First attempt at DMA support
solos: Tidy up DMA handling a little. Still untested
solos: Tidy up tx_mask handling for ports which need TX
solos: Remove unused loopback debug stuff
solos: Remove IRQF_DISABLED, don't frob IRQ enable on the FPGA in solos_irq()
solos: Remove superfluous wait_queue_head_t from struct solos_param
solos: Fix various bugs in status packet handling
solos: Clean up handling of card->tx_mask a little
solos: Remove debugging, commented-out test code
solos: Add 'reset' module parameter to reset the DSL chips on load
solos: Tidy up status interrupt handling, cope with 'ERROR' status
solos: Don't clear config registers at startup
solos: Set RX empty flag at startup only for !dma mode
solos: Swap upstream/downstream rates in status packet, clean up some more
solos: Reset device on unload, free pending skbs
solos: Disable DMA until we have an FPGA update with it actually implemented.
Nathan Williams (1):
solos: Automatically determine number of ports
Simon Farnsworth (2):
solos: Slight debugging improvements
solos: FPGA and firmware update support.
