net: phy: Fix missing of_node_put() for leds

[ Upstream commit 2560db6ede1aaf162a73b2df43e0b6c5ed8819f7 ]

The call of of_get_child_by_name() will cause refcount incremented
for leds, if it succeeds, it should call of_node_put() to decrease
it, fix it.

net: phy: realtek: add support for RTL8366S Gigabit PHY

2024-08-11T10:47:19+00:00

[ Upstream commit 225990c487c1023e7b3aa89beb6a68011fbc0461 ]

The PHY built in to the Realtek RTL8366S switch controller was
previously supported by genphy_driver. This PHY does not implement MMD
operations. Since commit 9b01c885be36 ("net: phy: c22: migrate to
genphy_c45_write_eee_adv()"), MMD register reads have been made during
phy_probe to determine EEE support. For genphy_driver, these reads are
transformed into 802.3 annex 22D clause 45-over-clause 22
mmd_phy_indirect operations that perform MII register writes to
MII_MMD_CTRL and MII_MMD_DATA. This overwrites those two MII registers,
which on this PHY are reserved and have another function, rendering the
PHY unusable while so configured.

Proper support for this PHY is restored by providing a phy_driver that
declares MMD operations as unsupported by using the helper functions
provided for that purpose, while remaining otherwise identical to
genphy_driver.

net: phy: mxl-gpy: Remove interrupt mask clearing from config_init

[ Upstream commit c44d3ffd85db03ebcc3090e55589e10d5af9f3a9 ]

When the system resumes from sleep, the phy_init_hw() function invokes
config_init(), which clears all interrupt masks and causes wake events to be
lost in subsequent wake sequences. Remove interrupt mask clearing from
config_init() and preserve relevant masks in config_intr().

net: sfp: Always call `sfp_sm_mod_remove()` on remove

[ Upstream commit e96b2933152fd87b6a41765b2f58b158fde855b6 ]

If the module is in SFP_MOD_ERROR, `sfp_sm_mod_remove()` will
not be run. As a consequence, `sfp_hwmon_remove()` is not getting
run either, leaving a stale `hwmon` device behind. `sfp_sm_mod_remove()`
itself checks `sfp->sm_mod_state` anyways, so this check was not
really needed in the first place.

net: phy: Micrel KSZ8061: fix errata solution not taking effect problem

2024-06-21T12:38:16+00:00

[ Upstream commit 0a8d3f2e3e8d8aea8af017e14227b91d5989b696 ]

KSZ8061 needs to write to a MMD register at driver initialization to fix
an errata.  This worked in 5.0 kernel but not in newer kernels.  The
issue is the main phylib code no longer resets PHY at the very beginning.
Calling phy resuming code later will reset the chip if it is already
powered down at the beginning.  This wipes out the MMD register write.
Solution is to implement a phy resume function for KSZ8061 to take care
of this problem.
