Subject: [PATCH net-next 0/4] net: phy: marvell10g: Firmware loading and LED support for 88X3310

There are two boot options for a 88X3310 PHY:

1. Device loads its firmware from a dedicated serial FLASH
2. Device waits for its firmware to be downloaded over XMDIO

1/4 adds support for the second option. The device reports which mode
it is in via a register, so we only attempt to load a firmware in this
situation. Crucially, if firmware is not available in this case, the
device is not usable _at all_, so we are forced to fail the probe
entirely.

2/4 extends the power up sequence to cover cases where the device has
been hardware strapped to start powered down, in which case all
internal units will be powered down.

3/4 adds support for the LED controller in the PHY. A special DT
attribute is added to control the polarity and drive behavior of each
LED, which we document in 4/4.
