+
+There are users inside and outside LED framework that have implemented
+a local copy of led_init_default_state_get(). In order to deduplicate
+that, as the first step move the declaration from LED header to the
+global one.

+
+Move qca8k_port_to_phy() to qca8k header as it's useful for future
+reference in Switch LEDs module since the same logic is applied to get
+the right index of the switch port.
+Make it inline as it's simple function that just decrease the port.

+Subject: [PATCH 2/9] net: dsa: qca8k: add LEDs basic support
+
+Add LEDs basic support for qca8k Switch Family by adding basic
+brightness_set() support.
+
+Since these LEDs refelect port status, the default label is set to
+":port". DT binding should describe the color and function of the
+LEDs using standard LEDs api.
+Each LED always have the device name as prefix. The device name is
+composed from the mii bus id and the PHY addr resulting in example
+names like:
+- qca8k-0.0:00:amber:lan
+- qca8k-0.0:00:white:lan
+- qca8k-0.0:01:amber:lan
+- qca8k-0.0:01:white:lan
+
+These LEDs supports only blocking variant of the brightness_set()
+function since they can sleep during access of the switch leds to set
+the brightness.
+
+While at it add to the qca8k header file each mode defined by the Switch
+Documentation for future use.

+Provide stubs for devm_led_classdev_register_ext() and

+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.

+Subject: [PATCH 5/9] net: phy: Add a binding for PHY LEDs
+
+Define common binding parsing for all PHY drivers with LEDs using
+phylib. Parse the DT as part of the phy_probe and add LEDs to the
+linux LED class infrastructure. For the moment, provide a dummy
+brightness function, which will later be replaced with a call into the
+PHY driver. This allows testing since the LED core might otherwise
+reject an LED whose brightness cannot be set.
+
+Add a dependency on LED_CLASS. It either needs to be built in, or not
+enabled, since a modular build can result in linker errors.

+ mode
+
+Putting NETDEV_LED_MODE_LINKUP in the same list of the netdev trigger
+modes is wrong as it's used to set the link state of the device and not
+to set a blink mode as it's done by NETDEV_LED_LINK, NETDEV_LED_TX and
+NETDEV_LED_RX. It's also wrong to put this state in the same bitmap of the
+netdev trigger mode and should be external to it.
+
+Drop NETDEV_LED_MODE_LINKUP from mode list and convert to a simple bool
+that will be true or false based on the carrier link. No functional
+change intended.

+Subject: [PATCH 3/5] leds: trigger: netdev: Rename add namespace to netdev
+ trigger enum modes
+
+Rename NETDEV trigger enum modes to a more symbolic name and add a
+namespace to them.
+
+Also add __TRIGGER_NETDEV_MAX to identify the max modes of the netdev
+trigger.
+
+This is a cleanup to drop the define and no behaviour change are
+intended.

+Subject: [PATCH 5/5] leds: trigger: netdev: Use mutex instead of spinlocks
+
+Some LEDs may require to sleep while doing some operation like setting
+brightness and other cleanup.
+
+For this reason, using a spinlock will cause a sleep under spinlock
+warning.
+
+It should be safe to convert this to a sleepable lock since:
+- sysfs read/write can sleep
+- netdev_trig_work is a work queue and can sleep
+- netdev _trig_notify can sleep
+
+The spinlock was used when brightness didn't support sleeping, but this
+changed and now it supported with brightness_set_blocking().
+
+Convert to mutex lock to permit sleeping using brightness_set_blocking().

++Hardware driven LEDs
++====================
++
++Some LEDs can be programmed to be driven by hardware. This is not
++limited to blink but also to turn off or on autonomously.
++To support this feature, a LED needs to implement various additional
++ops and needs to declare specific support for the supported triggers.
++
++With hw control we refer to the LED driven by hardware.
++
++LED driver must define the following value to support hw control:
++
++ - hw_control_trigger:
++ unique trigger name supported by the LED in hw control
++ mode.
++
++LED driver must implement the following API to support hw control:
++ - hw_control_is_supported:
++ check if the flags passed by the supported trigger can
++ be parsed and activate hw control on the LED.
++
++ Return 0 if the passed flags mask is supported and
++ can be set with hw_control_set().
++
++ If the passed flags mask is not supported -EOPNOTSUPP
++ must be returned, the LED trigger will use software
++ fallback in this case.
++
++ Return a negative error in case of any other error like
++ device not ready or timeouts.
++
++ - hw_control_set:
++ activate hw control. LED driver will use the provided
++ flags passed from the supported trigger, parse them to
++ a set of mode and setup the LED to be driven by hardware
++ following the requested modes.
++
++ Set LED_OFF via the brightness_set to deactivate hw control.
++
++ Return 0 on success, a negative error number on failing to
++ apply flags.
++
++ - hw_control_get:
++ get active modes from a LED already in hw control, parse
++ them and set in flags the current active flags for the
++ supported trigger.
++
++ Return 0 on success, a negative error number on failing
++ parsing the initial mode.
++ Error from this function is NOT FATAL as the device may
++ be in a not supported initial state by the attached LED
++ trigger.
++
++ - hw_control_get_device:
++ return the device associated with the LED driver in
++ hw control. A trigger might use this to match the
++ returned device from this function with a configured
++ device for the trigger as the source for blinking
++ events and correctly enable hw control.
++ (example a netdev trigger configured to blink for a
++ particular dev match the returned dev from get_device
++ to set hw control)
++
++ Returns a pointer to a struct device or NULL if nothing
++ is currently attached.
++
++LED driver can activate additional modes by default to workaround the
++impossibility of supporting each different mode on the supported trigger.
++Examples are hardcoding the blink speed to a set interval, enable special
++feature like bypassing blink if some requirements are not met.
++
++A trigger should first check if the hw control API are supported by the LED
++driver and check if the trigger is supported to verify if hw control is possible,
++use hw_control_is_supported to check if the flags are supported and only at
++the end use hw_control_set to activate hw control.
++
++A trigger can use hw_control_get to check if a LED is already in hw control
++and init their flags.
++
++When the LED is in hw control, no software blink is possible and doing so
++will effectively disable hw control.

+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.

+Subject: [PATCH 08/13] leds: trigger: netdev: add support for LED hw control
+
+Add support for LED hw control for the netdev trigger.
+
+The trigger on calling set_baseline_state to configure a new mode, will
+do various check to verify if hw control can be used for the requested
+mode in can_hw_control() function.
+
+It will first check if the LED driver supports hw control for the netdev
+trigger, then will use hw_control_is_supported() and finally will call
+hw_control_set() to apply the requested mode.
+
+To use such mode, interval MUST be set to the default value and net_dev
+MUST be set. If one of these 2 value are not valid, hw control will
+never be used and normal software fallback is used.
+
+The default interval value is moved to a define to make sure they are
+always synced.

+Subject: [PATCH 12/13] net: dsa: qca8k: implement hw_control ops
+
+Implement hw_control ops to drive Switch LEDs based on hardware events.
+
+Netdev trigger is the declared supported trigger for hw control
+operation and supports the following mode:
+- tx
+- rx
+
+When hw_control_set is called, LEDs are set to follow the requested
+mode.
+Each LEDs will blink at 4Hz by default.

+Subject: [PATCH 13/13] net: dsa: qca8k: add op to get ports netdev
+
+In order that the LED trigger can blink the switch MAC ports LED, it
+needs to know the netdev associated to the port. Add the callback to
+return the struct device of the netdev.
+
+Add an helper function qca8k_phy_to_port() to convert the phy back to
+dsa_port index, as we reference LED port based on the internal PHY
+index and needs to be converted back.
