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.

||||
+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.

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.

Subject: [PATCH 13/14] ARM: dts: imx6q-evi: Fix onboard hub reset line
|
||||
|
||||
Previously the onboard hub was made to work by treating its
|
||||
reset gpio as a regulator enable.
|
||||
Get rid of that kludge now that pwseq has added reset gpio support
|
||||
Move pin muxing the hub reset pin into the usbh1 group
