Subject: [PATCH 3/5] net: phy: add support for PHY LEDs polarity modes
|
|
|
|
Add support for PHY LEDs polarity modes. Some PHY require LED to be set
|
|
to active low to be turned ON. Adds support for this by declaring
|
|
active-low property in DT.
|
|
|
|
PHY driver needs to declare .led_polarity_set() to configure LED
|
|
polarity modes. Function will pass the index with the LED index and a
|
|
bitmap with all the required modes to set.
|
|
|
|
Current supported modes are:
|
|
- active-low with the flag PHY_LED_ACTIVE_LOW. LED is set to active-low
|
|
to turn it ON.
|
|
- inactive-high-impedance with the flag PHY_LED_INACTIVE_HIGH_IMPEDANCE.
|
|
LED is set to high impedance to turn it OFF.
