net: phy: marvell: Fix buffer overrun with stats counters

2019-04-26T16:06:14Z

marvell_get_sset_count() returns how many statistics counters there are. If the PHY supports fibre, there are 3, otherwise two. marvell_get_strings() does not make this distinction, and always returns 3 strings. This then often results in writing past the end of the buffer for the strings. Fixes: 2170fef78a40 ("Marvell phy: add field to get errors from fiber link.")

spi: Micrel eth switch: declare missing of table

2019-04-23T17:44:44Z

Add missing table for SPI driver relying on SPI device match since compatible is in a DT binding or in a DTS.

net: phy: bcm54xx: Encode link speed and activity into LEDs

2019-03-26T18:24:47Z

Previously the green and amber LEDs on this quad PHY were solid, to indicate an encoding of the link speed (10/100/1000). This keeps the LEDs always on just as before, but now they flash on Rx/Tx activity. Signed-off-by: Vladimir Oltean Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: don't clear BMCR in genphy_soft_reset

2019-03-26T00:08:21Z

So far we effectively clear the BMCR register. Some PHY's can deal with this (e.g. because they reset BMCR to a default as part of a soft-reset) whilst on others this causes issues because e.g. the autoneg bit is cleared. Marvell is an example, see also thread [0]. So let's be a little bit more gentle and leave all bits we're not interested in as-is. This change is needed for PHY drivers to properly deal with the original patch.

net: phy: Re-parent menus for MDIO bus drivers correctly

2019-03-24T00:55:21Z

After 90eff9096c01 ("net: phy: Allow splitting MDIO bus/device support from PHYs") the various MDIO bus drivers were no longer parented with config PHYLIB but with config MDIO_BUS which is not a menuconfig, fix this by depending on MDIO_DEVICE which is a menuconfig. This is visually nicer and less confusing for users. Fixes: 90eff9096c01 ("net: phy: Allow splitting MDIO bus/device support from PHYs") Signed-off-by: Florian Fainelli Signed-off-by: David S.

net: phy: Add DP83825I to the DP83822 driver

2019-03-21T20:21:14Z

Add the DP83825I ethernet PHY to the DP83822 driver. These devices share the same WoL register bits and addresses. The phy_driver init was made into a macro as there may be future devices appended to this driver that will share the register space. http://www.ti.com/lit/gpn/dp83825i Reviewed-by: Florian Fainelli Signed-off-by: Dan Murphy Signed-off-by: David S.

net: phy: meson-gxl: fix interrupt support

2019-03-15T22:33:43Z

If an interrupt is already pending when the interrupt is enabled on the GXL phy, no IRQ will ever be triggered. The fix is simply to make sure pending IRQs are cleared before setting up the irq mask.
