Hi all,
This is a follow-up for my last power sequence framework patch set [1].
According to Rob Herring and Ulf Hansson's comments[2]. The kinds of
power sequence instances will be added at postcore_initcall, the match
criteria is compatible string first, if the compatible string is not
matched b
The current dts describes USB HUB's property at USB controller's
entry, it is improper. The USB HUB should be the child node
under USB controller, and power sequence properties are under
it. Besides, using gpio pinctrl setting for USB2415's reset pin.

At device tree, we have no device node for chipidea core,
the glue layer's node is the parent node for host and udc

we let the core's device node equals glu

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 recogniz
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 crea

We can occasionally get -EINPROGRESS for pm_runtime_get.
This is happening when an interrupt is fired before PM runtime had time
to update the PM state to RESUMED.
In that case, don't print any error.

Sometime, a transfer may not be queued due to a race between runtime pm
and cppi41_dma_issue_pending().
Sometime, cppi41_runtime_resume() may be interrupted right before to
update device PM state to RESUMED.
When it happens, if a new dma transfer is issued, because the device is not
in active state

I've seen it. It's on my TODO list. I'll get to this in next week
