[PATCH v4 1/3] net: phy: mxl-86110: add basic support for led_brightness_set op

[Daniel Golle]

Add support for forcing each connected LED to be always on or always off
by implementing the led_brightness_set() op.
This is done by modifying the COM_EXT_LED_GEN_CFG register to enable
force-mode and forcing the LED either on or off.
When calling the led_hw_control_set() force-mode is again disabled for
that LED.
Implement mxl86110_modify_extended_reg() locked helper instead of
manually acquiring and releasing the MDIO bus lock for single
__mxl86110_modify_extended_reg() calls.

[PATCH v4 2/3] net: phy: mxl-86110: fix indentation in struct phy_driver

[Daniel Golle]

The .led_hw_control_get and .led_hw_control_set ops are indented with
spaces instead of tabs, unlike the rest of the values of the PHY's
struct phy_driver instance.
Use tabs instead of spaces resulting in a uniform indentation style.

[PATCH v4 3/3] net: phy: mxl-86110: add basic support for MxL86111 PHY

[Daniel Golle]

Add basic support for the MxL86111 PHY which in addition to the features
of the MxL86110 also comes with an SGMII interface.
Setup the interface mode and take care of in-band-an.

Currently only RGMII-to-UTP and SGMII-to-UTP modes are supported while the
PHY would also support RGMII-to-1000Base-X, including automatic selection
of the Fiber or UTP link depending on the presence of a link partner.
