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 4/9] leds: Provide stubs for when CLASS_LED & NEW_LEDS are
|
|
disabled
|
|
|
|
Provide stubs for devm_led_classdev_register_ext() and
|
|
led_init_default_state_get() so that LED drivers embedded within other
|
|
drivers such as PHYs and Ethernet switches still build when LEDS_CLASS
|
|
or NEW_LEDS are disabled. This also helps with Kconfig dependencies,
|
|
which are somewhat hairy for phylib and mdio and only get worse when
|
|
adding a dependency on LED_CLASS.
