SubjectRe: [PATCH v2 7/7] arm64: dts: marvell: Add a device tree for the iEi Puzzle-M801 board
Hello Andrew and Marek,

I will break the new patchset up and also add Gregory to the DT conversation.
Should I exclude this patch from this patchset or can I just add him to Cc?

First six LEDs are used to indicate port status and activity on the SFP+ ports.
Certainly, I will change this once the API is solved. There are currently many
similar boards with no real solution for the network LED triggers.

I'll add the color and correct the function properties for the LEDs.

Kind regards,
Luka
