[PATCH v3 0/7] net: phy: realtek: Enable configuration of RTL8211E LEDs and SSC

From: Matthias Kaehlcke
Date: Mon Jul 08 2019 - 15:25:15 EST


The Realtek RTL8211E allows customization of the PHY LED behavior,
like which LEDs are on for certain link speeds and which LEDs blink
when there is traffic. By default EEE LED mode is enabled, in which
a blinking LED is on for 400ms and off for 2s. This series adds
support for configuring the LED behavior through device tree
properties.

The RTL8211E supports Spread Spectrum Clocking (SSC), which reduces
clock noise that may affect other board functions. By default SSC
is disabled, this series adds support for enabling it through a
device tree property.

Certain registers on the RTL8211E can only be accessed through
a vendor specific extended page mechanism. Extended pages need
to be accessed for the LED configuration and enabling SSC. This
series adds helpers to facilitate accessing extended pages.
