Subject: [PATCH 09/14] power: add power sequence library
We have an well-known problem that the device needs to do some power
sequence before it can be recognized by related host, the typical
example like hard-wired mmc devices and usb devices.
This power sequence is hard to be described at device tree and handled by
related host driver, so we have created a common power sequence
library to cover this requirement. The core code has supplied
some common helpers for host driver, and individual power sequence
libraries handle kinds of power sequence for devices. The pwrseq
librares always need to allocate extra instance for compatible
string match.
pwrseq_generic is intended for general purpose of power sequence, which
handles gpios and clocks currently, and can cover other controls in
future. The host driver just needs to call of_pwrseq_on/of_pwrseq_off
if only one power sequence is needed, else call of_pwrseq_on_list
/of_pwrseq_off_list instead (eg, USB hub driver).
For new power sequence library, it needs to add its compatible string
and allocation function at pwrseq_match_table_list, then the pwrseq
core will match it with DT's, and choose this library at runtime.

+====================================
+Power Sequence Library
+====================================
+
+:Date: Feb, 2017
+:Author: Peter Chen <peter.chen@nxp.com>
+
+
+Introduction
+============
+
+We have an well-known problem that the device needs to do a power
+sequence before it can be recognized by related host, the typical
+examples are hard-wired mmc devices and usb devices. The host controller
+can't know what kinds of this device is in its bus if the power
+sequence has not done, since the related devices driver's probe calling
+is determined by runtime according to eunumeration results. Besides,
+the devices may have custom power sequence, so the power sequence library
+which is independent with the devices is needed.
+
+Design
+============
+
+The power sequence library includes the core file and customer power
+sequence library. The core file exports interfaces are called by
+host controller driver for power sequence and customer power sequence
+library files to register its power sequence instance to global
+power sequence list. The custom power sequence library creates power
+sequence instance and implement custom power sequence.
+
+Since the power sequence describes hardware design, the description is
+located at board description file, eg, device tree dts file. And
+a specific power sequence belongs to device, so its description
+is under the device node, please refer to:
+Documentation/devicetree/bindings/power/pwrseq/pwrseq-generic.txt
+
+Custom power sequence library allocates one power sequence instance at
+bootup periods using postcore_initcall, this static allocated instance is
+used to compare with device-tree (DT) node to see if this library can be
+used for the node or not. When the result is matched, the core API will
+try to get resourses (->get, implemented at each library) for power
+sequence, if all resources are got, it will try to allocate another
+instance for next possible request from host driver.
+
+Then, the host controller driver can carry out power sequence on for this
+DT node, the library will do corresponding operations, like open clocks,
+toggle gpio, etc. The power sequence off routine will close and free the
+resources, and is called when the parent is removed. And the power
+sequence suspend and resume routine can be called at host driver's
+suspend and resume routine if needed.
+
+The exported interfaces

Subject: [PATCH 10/14] usb: core: add power sequence handling for USB devices
Some hard-wired USB devices need to do power sequence to let the
device work normally, the typical power sequence like: enable USB
PHY clock, toggle reset pin, etc. But current Linux USB driver
lacks of such code to do it, it may cause some hard-wired USB devices
works abnormal or can't be recognized by controller at all.
In this patch, it calls power sequence library APIs to finish
the power sequence events. It will do power on sequence at hub's
probe for all devices under this hub (includes root hub).
At hub_disconnect, it will do power off sequence which is at powered
on list.

under USB controller, and power sequence properties are under
it. Besides, using gpio pinctrl setting for USB2415's reset pin.
