2012-12-05net/phy: Add interrupt support for dp83640 phy.Stephan Gatzka1-1/+77
Added functions for ack_interrupt and config_intr. Tested on an mpc5200b powerpc board. Signed-off-by: Stephan Gatzka <stephan.gatzka@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-09-22ptp: link the phc device to its parent deviceRichard Cochran1-1/+1
PTP Hardware Clock devices appear as class devices in sysfs. This patch changes the registration API to use the parent device, clarifying the clock's relationship to the underlying device.

2012-06-11phy: Use pr_<level>Joe Perches1-10/+13
Use a more current logging style. Add pr_fmt and missing newlines. Remove embedded prefixes. Neaten phy_print_status to avoid using KERN_CONT. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-01-12dp83640: Fix NOHZ local_softirq_pending 08 warningManfred Rudigier1-1/+1
Similar problem as in 481a8199142c050b72bff8a1956a49fd0a75bbe0 ("can: fix NOHZ local_softirq_pending 08 warning"). This fix replaces netif_rx() with netif_rx_ni() which has to be used from process/softirq context. Signed-off-by: Manfred Rudigier <manfred.rudigier@omicron.at> Signed-off-by: David S.

2011-10-24dp83640: free packet queues on removeRichard Cochran1-0/+7
If the PHY should disappear (for example, on an USB Ethernet MAC), then the driver would leak any undelivered time stamp packets. This commit fixes the issue by calling the appropriate functions to free any packets left in the transmit and receive queues. The driver first appeared in v3.0.

2011-10-24dp83640: use proper function to free transmit time stamping packetsRichard Cochran1-2/+2
The previous commit enforces a new rule for handling the cloned packets for transmit time stamping. These packets must not be freed using any other function than skb_complete_tx_timestamp. This commit fixes the one and only driver using this API. The driver first appeared in v3.0.

2011-09-29dp83640: reduce driver noiseRichard Cochran1-2/+2
The driver has two warning messages that might be triggered by normal use cases. When they appear, the messages give the impression of a never ending series of errors. This commit changes them to debug messages instead. Signed-off-by: Richard Cochran <richard.cochran@omicron.at> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-09-26dp83640: add time stamp insertion for sync messagesRichard Cochran1-13/+57
This commit adds one step support to the phyter. When enabled, the hardware does not provide time stamps for transmitted sync messages but instead inserts the stamp into the outgoing packet.

2011-09-26dp83640: enable six external events and one periodic outputRichard Cochran1-19/+116
This patch enables six external event channels and one periodic output. One GPIO is reserved for synchronizing multiple PHYs. The assignment of GPIO functions can be changed via a module parameter. The code supports multiple simultaneous events by inducing a PTP clock event for every channel marked in the PHY's extended status word.

2011-08-07dp83640: increase receive time stamp buffer sizeRichard Cochran1-3/+2
The dp83640 buffers receive time stamps from special PHY status frames, matching them to received PTP packets in a work queue. Because the timeout for orphaned time stamps is so long and the buffer is so small, the driver can drop time stamps under moderate PTP traffic. This commit fixes the issue by decreasing the timeout to (at least) one timer tick and increasing the buffer size.

2011-06-16dp83640: drop PHY status frames in the driver.Richard Cochran1-2/+2
The dp83640 PHY provides time stamp and other information via special PHY status frames. Previously, the driver decoded the frames and then let the network stack drop them. This works fine when the PTP messages come over UDP. However, when receiving PTP messages via L2 packets, this creates a problem. The status frames use the official PTP destination MAC address, and so they are delivered to user space along with the "real" frames, causing confusion for applications. This commit fixes the issue by simply dropping the PHY status frames in the driver. Signed-off-by: Richard Cochran <richard.cochran@omicron.at> Signed-off-by: David S. Miller <davem@conan.davemloft.net>
2011-06-16dp83640: fix phy status frame event parsingRichard Cochran1-5/+15
If two eternal time stamp events occur at nearly the same time, the phyter will add an extra word into the status frame. This commit fixes the parsing code to recognize and skip over the extra word.

2011-05-23ptp: Fix dp83640 build warning when building staticallyJohn Stultz1-1/+1
If the dp83640 driver is not built as a module, the MODULE_DEVICE_TABLE reference to dp83640_tbl nops out. Since the table isn't referenced elsewhere, it it causes the following warning: drivers/net/phy/dp83640.c:1095: warning: ‘dp83640_tbl’ defined but not used This apparently is common with mdio_device_id table structures, and is avoided by using __maybe_unused annotation.
