From b1f21329d4358e74864f17eedd0f887e5ad2a816 Mon Sep 17 00:00:00 2001 From: Robert Marko Date: Mon, 27 Dec 2021 15:11:18 +0100 Subject: ipq40xx: add DSA switch driver Qualcomm IPQ40xx SoC-s have a variant of QCA8337N switch built-in. It shares most of the stuff with its external counterpart, however it is modified for the SoC. Namely, it doesn't have second CPU port (Port 6), so it has 6 ports instead of 7. It also has no built-in PHY-s but rather requires external PSGMII based companion PHY-s (QCA8072 and QCA8075) for which it first needs to carry out calibration before using them. PSGMII has a SoC built-in PHY that is used to connect to the PHY-s which unfortunately requires some magic values as the datasheet doesnt document the bits that are being set or the register at all. Since its built-in it is MMIO like other peripherals and doesn't have its own MDIO bus but depends on the SoC provided one. CPU connection is at Port 0 and it uses some kind of a internal connection and no traditional RGMII/SGMII. It also doesn't use in-band tagging like other qca8k switches so a shinfo based tagger is used. This is based on the current OpenWrt qca8k version that has been imported from generic target.
