net/phy: Expose 100base-T capability only

2016-06-03T20:51:54+00:00

I don't know the specific PHY model deployed on Firestone BMC, but currently used one (PHY_ID_BCM54210E) isn't correct. BCM54210E supports 1000base-T but the PHY on Firestone BMC shouldn't support that mode as uboot uses 100base-T mode. When exposing 1000base-T capability, the MAC is forced to have the same mode though the PHY is working in 100base-T mode in fact. It causes the mode mismatch between PHY/MAC and the ethernet network doesn't work. It's a temporary fix. After the PHY model is confirmed, we need to enable the correct PHY driver instead current one for BCM54210E. Signed-off-by: Gavin Shan [Cyril] The plot thickens, it does appear that this IS the correct PHY on firestones. This patch is definitely required for networking to be functional though.

net: phylib: fix interrupts re-enablement in phy_start

2016-05-10T19:59:49+00:00

If phy was suspended and is starting, current driver always enable phy's interrupts, if phy works in polling, phy can raise unexpected interrupt which will not be handled, the interrupt will block system enter suspend again. So interrupts should only be re-enabled if phy works in interrupt. Signed-off-by: Shaohui Xie Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: at803x: only the AT8030 needs a hardware reset on link change

2016-04-28T20:48:21+00:00

Commit 13a56b44 ("at803x: Add support for hardware reset") added a work-around for a hardware bug on the AT8030. However, the work-around was being called for all 803x PHYs, even those that don't need it. Function at803x_link_change_notify() checks to make sure that it only resets the PHY on the 8030, but it makes more sense to not call that function at all if it isn't needed.

net: phy: spi_ks8895: Don't leak references to SPI devices

2016-04-21T19:00:27+00:00

The ks8895 driver is using spi_dev_get() apparently just to take a copy of the SPI device used to instantiate it but never calls spi_dev_put() to free it. Since the device is guaranteed to exist between probe() and remove() there should be no need for the driver to take an extra reference to it so fix the leak by just using a straight assignment.

net: phy: at803x: Request 'reset' GPIO only for AT8030 PHY

2016-03-23T17:39:25+00:00

This removes the dependency on GPIOLIB for non faulty PHYs. Indeed, without this patch, if GPIOLIB is not selected devm_gpiod_get_optional() will return -ENOSYS and the driver probe call will fail, regardless of the actual PHY hardware. Out of the 3 PHYs supported by this driver (AT8030, AT8031, AT8035), only AT8030 presents the issues that commit 13a56b449325 ("net: phy: at803x: Add support for hardware reset") attempts to work-around by using a 'reset' GPIO line. Hence, only AT8030 should depend on GPIOLIB operating properly. Fixes: 13a56b449325 ("net: phy: at803x: Add support for hardware reset") Signed-off-by: Sebastian Frias Signed-off-by: David S. Miller

at803x: fix reset handling

2016-03-23T17:38:40+00:00

The driver of course "knows" that the chip's reset signal is active low, so it drives the GPIO to 0 to reset the PHY and to 1 otherwise; however all this will only work iff the GPIO is specified as active-high in the device tree! I think both the driver and the device trees (if there are any -- I was unable to find them) need to be fixed in this case...
