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.

Subject: [PATCH 05/13] leds: trigger: netdev: introduce check for possible hw
|
|
control
|
|
|
|
Introduce function to check if the requested mode can use hw control in
|
|
preparation for hw control support. Currently everything is handled in
|
|
software so can_hw_control will always return false.
|
|
|
|
Add knob with the new value hw_control in trigger_data struct to
|
|
set hw control possible. Useful for future implementation to implement
|
|
in set_baseline_state() the required function to set the requested mode
|
|
using LEDs hw control ops and in other function to reject set if hw
|
|
control is currently active.
