* ar40xx_switch: add initial switch for the IPQ4018/IPQ4019.Adrian Chadd2022-02-0422-0/+4044
| | | | | | | | | | | | | | | | Summary: This switch is based off of the AR8327/AR8337 external switch/PHY. However unlike the AR8327/AR8337 it itself doesn't have any PHYs; instead an external PHY connects to it using the PSGMII port. Differential Revision: https://reviews.freebsd.org/D34112 Reviewed by: manu This code is inspired by the ar40xx code in openwrt, which itself is based on the Qualcomm QCA-SSDK. Both of these sources are, amusingly, BSD licenced - and thus I have included some of the comments in the hardware workaround paths to document some of the magic numbers.

| | | | | | | | | | | | | | | | | | | In the latest Linux kernel revisions the DSA (Distributed Switch Architecture) device tree binding was changed. Instead of the top level dsa@ node, the switch and its ports is represented as a child node of the mdio bus.

* Clean up OF_getprop_alloc APIOleksandr Tymoshenko2018-04-081-2/+2
| | | | | | | | | | | | | | | | | | | | OF_getprop_alloc takes element size argument and returns number of elements in the property. There are valid use cases for such behavior but mostly API consumers pass 1 as element size to get string properties. What API users would expect from OF_getprop_alloc is to be a combination of malloc + OF_getprop with the same semantic of return value. This patch modifies API signature to match these expectations. For the valid use cases with element size != 1 and to reduce modification scope new OF_getprop_alloc_multi function has been introduced that behaves the same way OF_getprop_alloc behaved prior to this patch.

| | | | | | | | | | | | | | | | This indeed uses the same registers as the AR8216 and later chips. There seems to be an issue with ARP requests being sent out from the CPU through this switch here, so figuring that out is next. Learning works fine on the AR8327 ethernet switch on the /other/ gigabit ethernet port, so I don't think it's the network stack or ethernet driver.

The table fetch/read methods pass through to the drivers for now since the drivers may implement different ways of fetching/caching the address table data. The atheros devices for example fetch the table by iterating over the table through a set of registers and so you need to keep that locked whilst you iterate otherwise you may have the table flushed half way by a port status change.
