* staging: octeon-ethernet: Move PHY activation to .ndo_open().David Daney2014-06-201-5/+18
| | | | | | | | | | | | | | | | | This prevents PHY not found types of errors for PHY drivers that are probed after the Ethernet driver is probed, because the ifconfig UP is done from userspace after all drivers have been probed. Also avoid the cvmx-helper-board.c PHY code if a real PHY driver is present, this allows a bootloader supplied device tree to specify the PHY information rather than having to modify the code for each different board.

* staging: octeon-ethernet: rgmii: enable interrupts that we can handleAaro Koskinen2013-09-171-3/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enable only those interrupts that we can handle & acknowledge in the interrupt handler. At least on EdgeRouter Lite, the hardware may occasionally interrupt with some error condition when the physical link status changes frequently. Since the interrupt condition is not acked properly, this leads to the following warning and the IRQ gets disabled completely: [ 41.324700] eth0: Link down [ 44.324721] eth0: 1000 Mbps Full duplex, port 0, queue 0 [ 44.885590] irq 117: nobody cared (try booting with the "irqpoll" option) [ 44.892397] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 3.11.0-rc5-edge-los.git-27d042f-dirty-00950-gaa42f2d-dirty #8 [ 44.902825] Stack : ffffffff815c0000 0000000000000004 0000000000000003 0000000000000000 ffffffff81fd0000 ffffffff815c0000 0000000000000004 ffffffff8118530c ffffffff815c0000 ffffffff811858d8 0000000000000000 0000000000000000 ffffffff81fd0000 ffffffff81fc0000 ffffffff8152f3a0 ffffffff815b7bf7 ffffffff81fc6688 ffffffff815b8060 0000000000000000 0000000000000000 0000000000000000 ffffffff815346c8 ffffffff815346b0 ffffffff814a6a18 ffffffff8158b848 ffffffff81145614 ffffffff81593800 ffffffff81187174 ffffffff815b7d00 ffffffff8158b760 0000000000000000 ffffffff814a9184 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 ffffffff811203b8 0000000000000000 0000000000000000 ...

* Staging: Add octeon-ethernet driver files.David Daney2009-06-171-0/+397
The octeon-ethernet driver supports the sgmii, rgmii, spi, and xaui ports present on the Cavium OCTEON family of SOCs. These SOCs are multi-core mips64 processors with existing support over in arch/mips. The driver files can be categorized into three basic groups: 1) Register definitions, these are named cvmx-*-defs.h 2) Main driver code, these have names that don't start cvmx-. 3) Interface specific functions and other utility code, names starting with cvmx- Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
