From: Linus Walleij Date: Fri, 9 Aug 2024 09:45:04 +0000 (+0200) Subject: linux: generic: net: dsa: mv88e6xxx LED support X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c990f6e156699a4a60967603fb19b96a251a0bba;p=openwrt%2Fopenwrt.git linux: generic: net: dsa: mv88e6xxx LED support This solution that is needed for some routers to provide proper LED activity when controlled directly by the MV88E6xxx switch, has just been merged in upstream Linux. Make this patch 901 as other backports from earlier kernels are in patch 896 and this is the first free number after that. Patch offsets in pending patches are augmented as part of the refresh.

It is also possible to be more elaborate, like this: + + cd /sys/class/leds/Marvell\ 88E6352:05:00:green:wan/ + echo netdev > trigger + echo 1 > link_1000 + cd /sys/class/leds/Marvell\ 88E6352:05:01:amber:wan/ + echo netdev > trigger + echo 1 > link_100 + +Making the green LED come on for a gigabit link and the +amber LED come on for a 100 mbit link. + +Each port has 2 LED slots (the hardware may use just one or +none) and the hardware triggers are specified in four bits per +LED, and some of the hardware triggers are only available on the +SFP (fiber) uplink. The restrictions are described in the +port.h header file where the registers are described. For +example, selector 1 set for LED 1 on port 5 or 6 will indicate +Fiber 1000 (gigabit) and activity with a blinking LED, but +ONLY for an SFP connection. If port 5/6 is used with something +not SFP, this selector is a noop: something else need to be +selected. + +After the previous series rewriting the MV88E6xxx DT +bindings to use YAML a "leds" subnode is already valid +for each port, in my scratch device tree it looks like +this: + + leds { + #address-cells = <1>; + #size-cells = <0>; + + led@0 { + reg = <0>; + color = ; + function = LED_FUNCTION_LAN; + default-state = "off"; + linux,default-trigger = "netdev"; + }; + led@1 { + reg = <1>; + color = ; + function = LED_FUNCTION_LAN; + default-state = "off"; + }; + }; + +This DT config is not yet configuring everything: when the netdev +default trigger is assigned the hw acceleration callbacks are +not called, and there is no way to set the netdev sub-trigger +type (such as link_1000) from the device tree, such as if you want +a gigabit link indicator. This has to be done from userspace at +this point. + +We add LED operations to all switches in the 6352 family: +6172, 6176, 6240 and 6352. + +Signed-off-by: Linus Walleij +--- +
