let's rely on evt->length which is the actual length

This series require the following patch to build:
[PATCH 1/6] usb: musb: Fix broken use of static variable for multiple instances
Currently, the USB OTG of the da8xx doesn't work.
This series intend to fix them.
Change in v2:
* Fix the error path da8xx_musb_init()
Changes in v3:
* Remove the hos
The DA8xx OTG PHY has some issues when it is forced in host or
peripheral mode. Actually, most of the time, OTG is the best mode
because host or peripheral mode are only required for hardware that
miss some circuitry.
Init the PHY mode OTG mode by default.

We can't use static variable first for checking when musb is
initialized when we have multiple musb instances like on am335x.

With a USB hub disconnected, devctl can be 0x19 for about a second

Hi all,
Here's v3 of musb fixes for issues that I've been able to track down.
The PM changes merged for v4.9 popped up various issues reported by
people that I had not seen earlier with my tests.
As many people depend on this driver, I'd like to have these merged
for v4.9-rc cycle.

Commit 65b3f50ed6fa ("usb: musb: Add PM runtime support for MUSB DSPS
glue layer") wrongly added a call for pm_runtime_get_sync to otg_timer
that runs in softirq context. That causes a "BUG: sleeping function called
from invalid context" every time when polling the cable status:
[] (__might_sleep)
We are missing pm_runtime_disable() in 2430 glue layer. Further,
we only need to enable PM runtime and disable it on exit. With
musb_core.c doing PM, the glue layer as a parent will always be
active when musb_core.c is active.
This fixes host enumeration issues with some devices as reported
by Lad
Now with musb driver implementing generic session bit based
PM, we need to have the USB PHYs behaving in a sane way for
platforms implementing PM.
Currently twl4030-usb enables PM in twl4030_phy_power_on()
and then disables it in twl4030_phy_power_off(). This will
block PM runtime for the SoC when
This already gets done automatically by PM runtime and we have
a separate autosuspend timeout in musb_core.c.

Hey folks,
I wanted to send out these patches again for comment.

We've seen failures when switching between host and gadget mode,
which was diagnosed as being caused due to the bus being
auto-suspended when we switched.
So this patch forces a port resume when switching to device
mode if the bus is suspended.

This patch adds support for the "amcc,usb-otg" device
which is found in the PowerPC Canyonlands' dts.

In 4.8.6 and 4.9-rc5, the gadget serial driver crashes during
deinitialisation when compiled with CONFIG_U_SERIAL_CONSOLE.
Steps to reproduce:

The problem also occurs when using configfs, when the UDC is unbound.

This series adds a binding for AHB burst, reads it in, and configures
the controller for the specified burst type.

Add the "snps,ahb-burst" binding and read it in.
This property controls which burst type to perform on the AHB bus as a
master in internal DMA mode. This overrides the legacy param value,
which we need to keep around for now since several platforms use it.
Some platforms may see better or worse p
