Although the AN8855 eFuse driver was merged upstream, other
drivers were not. Restore Kconfig dependencies to enable it.
Also remove useless change logs from the patch.

Subject: [net-next PATCH v11 0/9] net: dsa: Add Airoha AN8855 support
|
|
Date: Mon, 9 Dec 2024 14:44:17 +0100 [thread overview]
|
|
Message-ID: <20241209134459.27110-1-ansuelsmth@gmail.com> (raw)
|
|
|
|
This small series add the initial support for the Airoha AN8855 Switch.
|
|
|
|
It's a 5 port Gigabit Switch with SGMII/HSGMII upstream port.
|
|
|
|
This is starting to get in the wild and there are already some router
|
|
having this switch chip.
|
|
|
|
It's conceptually similar to mediatek switch but register and bits
|
|
are different. And there is that massive Hell that is the PCS
|
|
configuration.
|
|
Saddly for that part we have absolutely NO documentation currently.
|
|
|
|
There is this special thing where PHY needs to be calibrated with values
|
|
from the switch efuse. (the thing have a whole cpu timer and MCU)
