mips: dts: Add support for Cisco SG220-26 switchSigned-off-by: Bert Vermeulen <bert@biot.com>Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
Add support for Realtek RTL838x/RTL839x switch SoCsThe RTL838x/839x family of SoCs are Realtek switches with an embeddedMIPS core.* RTL838x - 500MHz 4kce single core - 1Gbit ports and L2 feature
Add support for Realtek RTL838x/RTL839x switch SoCsThe RTL838x/839x family of SoCs are Realtek switches with an embeddedMIPS core.* RTL838x - 500MHz 4kce single core - 1Gbit ports and L2 features* RTL839x - 700MHz 34Kc single core - 1Gbit ports and L2 featuresThese switches, depending on the exact part number, will have anywherebetween 8 and 52 ports. The MIPS core is wired to a switch cpu port whichhas a tagging feature allowing us to make use of the DSA subsystem.The SoCs are somewhat basic in certain areas, getting better with moreadvanced features on newer series.The switch functionality is MMIO-mapped via a large MFD region.The SoCs have the following peripherals* ethernet* switch* uart - ns16550a* spi-flash interface* gpio* wdt* ledThe code was derived from various vendor SDKs based on Linux v2.6kernels.This patchset allows us to boot RTL838x/RTL839x units with basic support.Most of the other drivers are already written and functional, and work toget them upstream is already in progress.Signed-off-by: Birger Koblitz <mail@birger-koblitz.de>Signed-off-by: Bert Vermeulen <bert@biot.com>Signed-off-by: John Crispin <john@phrozen.org>Signed-off-by: Sander Vanheule <sander@svanheule.net>Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
