net: dp83822: disable rx error interrupt

2022-06-24T23:33:22+00:00

Some RX errors, notably when disconnecting the cable, increase the RCSR register. Once half full (0x7fff), an interrupt flood is generated. I measured ~3k/s interrupts even after the RX errors transfer was stopped. Since we don't read and clear the RCSR register, we should disable this interrupt.

net: dp83822: disable false carrier interrupt

2022-06-24T23:32:34+00:00

When unplugging an Ethernet cable, false carrier events were produced by the PHY at a very high rate. Once the false carrier counter full, an interrupt was triggered every few clock cycles until the cable was replugged. This resulted in approximately 10k/s interrupts. Since the false carrier counter (FCSCR) is never used, we can safely disable this interrupt. In addition to improving performance, this also solved MDIO read timeouts I was randomly encountering with an i.MX8 fec MAC because of the interrupt flood. The interrupt count and MDIO timeout fix were tested on a v5.4.110 kernel.

net: phy: Add support for 1PPS out and external timestamps

2022-06-24T03:49:02+00:00

The perout function is used to generate a 1PPS signal, synchronized to the PHC. This is accomplished by a using the hardware oneshot functionality, which is reset by a timer. The external timestamp function is set up for a 1PPS input pulse, and uses a timer to poll for temestamps. Both functions use the SYNC_OUT/SYNC_IN1 pin, so cannot run simultaneously.

Add 'struct bcm_ptp_private' to bcm54xx_phy_priv which points to an optional PTP structure attached to the PHY. This is allocated on probe if PHY PTP support is configured, and if the driver supports PTP for the specified PHY. Add the bcm_ptp_probe(), bcm_ptp_config_init() and bcn_ptp_stop() API functions to the bcm-phy library.
