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 10/13] leds: trigger: netdev: init mode if hw control already
|
|
active
|
|
|
|
On netdev trigger activation, hw control may be already active by
|
|
default. If this is the case and a device is actually provided by
|
|
hw_control_get_device(), init the already active mode and set the
|
|
bool to hw_control bool to true to reflect the already set mode in the
|
|
trigger_data.
