* enc28j60: don't specify (wrong) IRQ typeDavid Brownell2008-07-291-2/+4
| | | | | | | | | | | | | | | | | Recent changes to the IRQ framework have made passing the wrong trigger type to request_irq() become a fatal error. In the case of the enc28j60 driver, it stopped working in my test harness. (Specifically: the signal detects "pin change" events, both edges, not just falling edges. Similarly, other boards might route it through an inverter. Trigger type are board-specific.) This fixes that problem by the usual fix of expecting board setup code to have set up the correct IRQ trigger type. The best known example of that being x86 setup.

* net/enc28j60: low power modeDavid Brownell2008-06-171-24/+58
| | | | | | | | | | | | | | | | Keep enc28j60 chips in low-power mode when they're not in use. At typically 120 mA, these chips run hot even when idle; this low power mode cuts that power usage by a factor of around 100. This version provides a generic routine to poll a register until its masked value equals some value ... e.g. bit set or cleared. It's basically what the previous wait_phy_ready() did, but this version is generalized to support the handshaking needed to enter and exit low power mode.

* net/enc28j60: oops fixDavid Brownell2008-03-051-1/+2
| | | | | | | | | Prevent oops on enc28j60 packet RX: make sure buffers are aligned. Not all architectures support unaligned accesses in kernel space.
