dsa: mt7530: Utilize REGMAP_IRQ for interrupt handlingReplace the custom IRQ chip handler and mask/unmask functions withREGMAP_IRQ. This significantly simplifies the code and allows for theremoval of almost all interrupt-related functions from mt7530.c.Tested on MT7988A built-in switch (MMIO) as well as MT7531AE IC (MDIO).Signed-off-by: Daniel Golle Acked-by: Chester A.

e3386ec4 - net: dsa: vsc73xx: Implement the tag_8021q VLAN operations

Sat, 13 Jul 2024 21:16:14 +0000

net: dsa: vsc73xx: Implement the tag_8021q VLAN operationsThis patch is a simple implementation of 802.1q tagging in the vsc73xxdriver. Currently, devices with DSA_TAG_PROTO_NONE are not functional.The VSC73XX family doesn't provide any tag support for external Ethernetports.The only option available is VLAN-based tagging, which requires constanthardware VLAN filtering. While the VSC73XX family supports providerbridging, it only supports QinQ without full implementation of 802.1AD.This means it only allows the doubled 0x8100 TPID.In the simple port mode, QinQ is enabled to preserve forwarding ofVLAN-tagged frames.Signed-off-by: Pawel Dembicki Reviewed-by: Vladimir Oltean Link: https://patch.msgid.link/20240713211620.1125910-9-paweldembicki@gmail.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/dsa/Kconfig

Mon, 18 Oct 2021 09:38:01 +0000

net: dsa: realtek-smi: add rtl8365mb subdriver for RTL8365MB-VCThis patch adds a realtek-smi subdriver for the RTL8365MB-VC 4+1 port10/100/1000M switch controller. The driver has been developed based on aGPL-licensed OS-agnostic Realtek vendor driver known as rtl8367c foundin the OpenWrt source tree.Despite the name, the RTL8365MB-VC has an entirely different registerlayout to the already-supported RTL8366RB ASIC. Notwithstanding this,the structure of the rtl8365mb subdriver is loosely based on the rtl8366rbsubdriver. Like the 'rb, it establishes its own irqchip to handlecascaded PHY link status interrupts.The RTL8365MB-VC switch is capable of offloading a large number offeatures from the software, but this patch introduces only the mostbasic DSA driver functionality. The ports always function as standaloneports, with bridging handled in software.One more thing. Realtek's nomenclature for switches makes it hard toknow exactly what other ASICs might be supported by this driver. Thevendor driver goes by the name rtl8367c, but as far as I can tell, nochip actually exists under this name. As such, the subdriver is namedrtl8365mb to emphasize the potentially limited support. But it is clearfrom the vendor sources that a number of other more advanced switchesshare a similar register layout, and further support should not be toohard to add given access to the relevant hardware. With this in mind,the subdriver has been written with as few assumptions about theparticular chip as is reasonable. But the RTL8365MB-VC is the onlyhardware I have available, so some further work is surely needed.Co-developed-by: Michael Rasmussen Signed-off-by: Michael Rasmussen Signed-off-by: Alvin Šipraga Reviewed-by: Vladimir Oltean Reviewed-by: Linus Walleij Reviewed-by: Florian Fainelli Tested-by: Arınç ÜNAL Signed-off-by: David S.

227d7206 - dsa: simplify Kconfig symbols and dependencies

Fri, 19 Mar 2021 15:46:30 +0000

dsa: simplify Kconfig symbols and dependencies1. Remove CONFIG_HAVE_NET_DSA.CONFIG_HAVE_NET_DSA is a legacy leftover from the times when driversshould have selected CONFIG_NET_DSA manually.Currently, all drivers has explicit 'depends on NET_DSA', so this isno more needed.2. CONFIG_HAVE_NET_DSA dependencies became CONFIG_NET_DSA's ones. - dropped !S390 dependency which was introduced to be sure NET_DSA can select CONFIG_PHYLIB. DSA migrated to Phylink almost 3 years ago and the PHY library itself doesn't depend on !S390 since commit 870a2b5e4fcd ("phylib: remove !S390 dependeny from Kconfig"); - INET dependency is kept to be sure we can select NET_SWITCHDEV; - NETDEVICES dependency is kept to be sure we can select PHYLINK.3. DSA drivers menu now depends on NET_DSA.Instead on 'depends on NET_DSA' on every single driver, the entiremenu now depends on it. This eliminates a lot of duplicated linesfrom Kconfig with no loss (when CONFIG_NET_DSA=m, drivers also canbe only m or n).This also has a nice side effect that there's no more empty menu onconfigurations without DSA.4. Kbuild will now descend into 'drivers/net/dsa' only when CONFIG_NET_DSA is y or m.This is safe since no objects inside this folder can be built withoutDSA core, as well as when CONFIG_NET_DSA=m, no objects can bebuilt-in.Signed-off-by: Alexander Lobakin Reviewed-by: Vladimir Oltean Reviewed-by: Florian Fainelli Signed-off-by: David S.
