Subject: [PATCH RFC net-next 0/8] DSA LED infrastructure, mv88e6xxx and QCA8K
Date: Wed, 29 Nov 2023 00:21:27 +0100	[thread overview]
Message-ID: <20231128232135.358638-1-andrew@lunn.ch> (raw)

This patchset extends the DSA core to add support for port LEDs being
controlled via sys/class/leds, and offloading blinking via
ledtrig-netdev. The core parses the device tree binding, and registers
LEDs. The DSA switch ops structure is extended with the needed
functions.

The mv88e6xxx support is partially added. Support for setting the
brightness and blinking is provided, but offloading of blinking is not
yet available. To demonstrate this, the wrt1900ac device tree is
extended with LEDs.

The existing QCA8K code is refactored to make use of this shared code.

RFC:

Linus, can you rework your code into this for offloading blinking ?
And test with ports 5 & 6.

Christian: Please test QCA8K. I would not be surprised if there is an
off-by-one.
