net: mdio: introduce a shutdown method to mdio device drivers

2021-10-09T12:39:49Z

[ Upstream commit cf9579976f724ad517cc15b7caadea728c7e245c ] MDIO-attached devices might have interrupts and other things that might need quiesced when we kexec into a new kernel. Things are even more creepy when those interrupt lines are shared, and in that case it is absolutely mandatory to disable all interrupt sources. Moreover, MDIO devices might be DSA switches, and DSA needs its own shutdown method to unlink from the DSA master, which is a new requirement that appeared after commit 2f1e8ea726e9 ("net: dsa: link interfaces with the DSA master to get rid of lockdep warnings"). So introduce a ->shutdown method in the MDIO device driver structure. Signed-off-by: Vladimir Oltean Reviewed-by: Andrew Lunn Reviewed-by: Florian Fainelli Signed-off-by: David S.

net: mdio: rename mdio_device reset to reset_gpio

This renames the GPIO reset of mdio devices from 'reset' to 'reset_gpio' to better differentiate between GPIO and reset-controller driven reset line. Signed-off-by: David Bauer Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: add helper mii_10gbt_stat_mod_linkmode_lpa_t

2019-02-19T00:43:54Z

Similar to the existing helpers for the Clause 22 registers add helper mii_10gbt_stat_mod_linkmode_lpa_t. Note that this helper is defined in linux/mdio.h, not like the Clause 22 helpers in linux/mii.h. Reason is that the Clause 45 register constants are defined in uapi/linux/mdio.h. And uapi/linux/mdio.h includes linux/mii.h before defining the C45 register constants. v2: - remove helpers that don't have users in this series Signed-off-by: Heiner Kallweit Reviewed-by: Florian Fainelli Signed-off-by: David S.

net: phy: remove PM ops from MDIO bus

2018-06-05T12:50:16Z

Current implementation of MDIO bus PM ops doesn't actually implement bus-specific PM ops but just calls PM ops defined on a device level what doesn't seem to be fully in line with the core PM model. When looking e.g. at __device_suspend() the PM core looks for PM ops of a device in a specific order: 1. device PM domain 2. device type 3. device class 4. device bus I think it has good reason that there's no PM ops on device level. Now that a device type representation of PHY's as special type of MDIO devices was added (only user of MDIO bus PM ops), the MDIO bus PM ops can be removed including member pm of struct mdio_device. If for some other type of MDIO device PM ops are needed, it should be modeled as struct device_type as well. Signed-off-by: Heiner Kallweit Signed-off-by: David S. Miller
