The fc_transport_template initializes the port_id member to the

Making led_set_brightness_sync() use led_set_brightness_nosleep() has 2
advantages:
- works for LED controllers that do not provide brightness_set_blocking()
- When the blocking callback is used, it uses the workqueue to update the
LED state, removing the need for mutual exclusion between
led_s

This series makes it possible for the LED core to manage the power supply
of a LED. It uses the regulator API to disable/enable the power if when the
LED is turned on/off.
This is especially useful in situations where the LED driver/controller is
not supplying the power.
Because updating a regulato
Most of the LEDs are powered by a voltage/current regulator. Describing it
in the device-tree makes it possible for the LED core to enable/disable it
when needed.

Hi,
this is a respin of getting the support for the Layerscape's external interrupt

The LS1021A allows inverting the polarity of six interrupt lines
IRQ[0:5] via the scfg_intpcr register, effectively allowing
IRQ_TYPE_LEVEL_LOW and IRQ_TYPE_EDGE_FALLING for those. We just need to

For unloading an ACPI table, it is necessary to provide the
index of the table. The method intended for dynamically
loading or hotplug addition of tables, acpi_load_table(),
does not provide this information, so a new function

update_max_interval() is called in both CPUHP_AP_SCHED_STARTING's startup
and teardown callbacks, but it turns out it's also called at the end of
