Backport initial LEDs hw control support. Currently this is limited to only rx/tx and link events for the netdev trigger but the API got accepted and the additional modes are working on and will be backported later. Refresh every patch and add the additional config flag for QCA8K new LEDs support. Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>

Subject: [PATCH 9/9] net: phy: marvell: Implement led_blink_set()
|
|
|
|
The Marvell PHY can blink the LEDs, simple on/off. All LEDs blink at
|
|
the same rate, and the reset default is 84ms per blink, which is
|
|
around 12Hz.
