Subject: [PATCH RFC leds + net-next v3 0/2] Add support for LEDs on Marvell PHYs

Hi,

this is v3 of my RFC adding support for LEDs connected to Marvell PHYs.

Please note that if you want to test this, you still need to first apply
the patch adding the LED private triggers support from Pavel's tree.
https://git.kernel.org/pub/scm/linux/kernel/git/pavel/linux-leds.git/commit/?h=for-next&id=93690cdf3060c61dfce813121d0bfc055e7fa30d

Changes since v2:
- to share code with other drivers which may want to also offer PHY HW
  control of LEDs some of the code was refactored and now resides in
  phy_hw_led_mode.c. This code is compiled in when config option
  LED_TRIGGER_PHY_HW is enabled. Drivers wanting to offer PHY HW control
  of LEDs should depend on this option.
- the "hw-control" trigger is renamed to "phydev-hw-mode" and is
  registered by the code in phy_hw_led_mode.c
- the "hw_control" sysfs file is renamed to "hw_mode"
- struct phy_driver is extended by three methods to support PHY HW LED
  control
- I renamed the various HW control modes offeret by Marvell PHYs to
  conform to other Linux mode names, for example the "1000/100/10/else"
  mode was renamed to "1Gbps/100Mbps/10Mbps", or "recv/else" was renamed
  to "rx" (this is the name of the mode in netdev trigger).
