This patch adds a function to program a customized LED setting for Realtek 81xx family. It reads the settings from devicetree under target board and programs the setting to offset 0x18 and 0x19. BUG=b:65437780 TEST=Add customized_leds register in devicetree.cb under target board, enable RT8168_SET_LED_MODE flag. Make sure the setting is programmed correctly to offset 0x18 and 0x19. Observed the LEDs were behaving as expected. Executed suspend/resume and the LEDs were still working as expected.

This is a string to set the mac address on a Realtek rt8168 card.
|
|
It must be in the form of "xx:xx:xx:xx:xx:xx", where x is a
|
|
hexadecimal number for it to be valid. Failing to do so will
|
|
result in the default macaddress being used.

This is to set a customized LED mode to distinguish 10/100/1000
|
|
link and speed status with limited LEDs avaiable on a board.

Please refer to RTL811x datasheet section 7.2 Customizable LED
|
|
Configuration for details. With this flag enabled, the
|
|
customized_leds variable will be read from devicetree setting.
