Hello,

this RFC series adds API for transparent offloading of LED triggers
to hardware and implements this for the netdev trigger.
It is then used by Marvell PHY driver, which gains support for
probing LEDs connected to a PHY chip.

When a netdev trigger is enabled on a Marvell PHY LED and configured
in a compatible setting (the network device in the trigger settings must
be the one attached to the PHY, and the link/tx/rx/interval settings
must be supported by that particular LED), instead of blinking the LED
in software, blinking is done by the PHY itself.

Marek Behún (7):
  leds: trigger: netdev: don't explicitly zero kzalloced data
  leds: trigger: netdev: simplify the driver by using bit field members
  leds: trigger: add API for HW offloading of triggers
  leds: trigger: netdev: support HW offloading
  net: phy: add simple incrementing phyindex member to phy_device struct
  net: phy: add support for LEDs connected to ethernet PHYs
  net: phy: marvell: support LEDs connected on Marvell PHYs
