Subject: [PATCH net-next v2 0/5] net: dsa: microchip: ksz8795: add Wake on LAN support

From: Pieter Van Trappen <pieter.van.trappen@...n.ch>

Add WoL support for KSZ8795 family of switches. This code was tested
with a KSZ8794 chip.

Strongly based on existing KSZ9477 code which has now been moved to
ksz_common instead of duplicating, as proposed during the review of
the v1 version of this patch.

In addition to the device-tree addition and the actual code, there's
an additional patch to check the erratum workaround application using
the now available indirect register read.

Signed-off-by: Pieter Van Trappen <pieter.van.trappen@...n.ch>

v2:
 - generalize instead of duplicate, much improved
 - variable declaration reverse Christmas tree
 - ksz8_handle_global_errata: return -EIO in case of indirect write failure
 - ksz8_ind_read8/write8: document functions
 - ksz8_handle_wake_reason: no need for additional write to clear
 - fix wakeup_source origin comments
v1: https://lore.kernel.org/netdev/20240717193725.469192-1-vtpieter@gmail.com/
