2019-08-16net: phy: adin: add support for Analog Devices PHYsAlexandru Ardelean
This change adds support for Analog Devices Industrial Ethernet PHYs. Particularly the PHYs this driver adds support for: * ADIN1200 - Robust, Industrial, Low Power 10/100 Ethernet PHY * ADIN1300 - Robust, Industrial, Low Latency 10/100/1000 Gigabit Ethernet PHY The 2 chips are register compatible with one another. The main difference being that ADIN1200 doesn't operate in gigabit mode. The chips can be operated by the Generic PHY driver as well via the standard IEEE PHY registers (0x0000 - 0x000F) which are supported by the kernel as well. This assumes that configuration of the PHY has been done completely in HW, according to spec. Configuration can also be done via registers, which will be supported by this driver.

Antoine Tenart says: ==================== net: mscc: PTP Hardware Clock (PHC) support This series introduces the PTP Hardware Clock (PHC) support to the Mscc Ocelot switch driver. In order to make use of this, a new register bank is added and described in the device tree, as well as a new interrupt. The use this bank and interrupt was made optional in the driver for dt compatibility reasons. Thanks! Antoine Since v5: - Made sure both the PTP interrupt and register bank were available to enable supporting h/w timestamping. - Added a check after a kzalloc. - Add Reviewed-by tags from Andrew. Since v4: - Added SKBTX_IN_PROGRESS. - Fixed two xmas trees. - Rework the loop condition in ocelot_ptp_rdy_irq_handler. Since v3: - Fixed a spin_unlock_irqrestore issue. Since v2: - Prevented from a possible infinite loop when reading the h/w timestamps. - s/GFP_KERNEL/GFP_ATOMIC/ in the Tx path. - Set rx_filter to HWTSTAMP_FILTER_PTP_V2_EVENT at probe. - Fixed s/w timestamping dependencies. - Added Paul Burton's Acked-by on patches 2 and 4. Since v1: - Used list_for_each_safe() in ocelot_deinit(). - Fixed a memory leak in ocelot_deinit() by calling dev_kfree_skb_any(). - Fixed a locking issue in get_hwtimestamp(). - Handled the NULL case of ptp_clock_register(). - Added comments on optional dt properties. ==================== Signed-off-by: David S.

phy_speed_down_core provides most of the functionality for phy_speed_down. It makes use of new helper phy_resolve_min_speed that is based on the sorting of the settings[] array. In certain cases it may be helpful to be able to exclude legacy half duplex modes, therefore prepare phy_resolve_min_speed() for it. v2: - rename __phy_speed_down to phy_speed_down_core Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com>
2019-08-13net: phy: add __set_linkmode_max_speedHeiner Kallweit
We will need the functionality of __set_linkmode_max_speed also for linkmode bitmaps other than phydev->supported. Therefore split it. v2: - remove unused parameter from __set_linkmode_max_speed Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com>
