At least on n900 we have phy-twl4030-usb only generating cable
interrupts, and then have a separate USB PHY.
In order for musb to know the real cable status, we need to
clear any cached state until musb is ready. Otherwise the cable
status interrupts will get just ignored if the status does
not change from the initial state.
To do this, let's add a return value to musb_mailbox(), and
reset cached linkstat to MUSB_UNKNOWN on error. Sorry to cause
a bit of churn here, I should have added that already last time
patching musb_mailbox().

The musb_hdrc_platform_data::config was defined as a non-const pointer.
However some drivers (e.g. the ux500) set up this pointer to point to a
static structure, which is potentially dangerous. Since the musb core
uses the pointer in a read-only manner the const qualifier was added to
protect the content of the config.

We currently can't unload omap2430 MUSB platform glue driver module and
this cause issues for fixing the MUSB code further. The reason we can't
remove omap2430 is because it uses the PHY functions and also exports the
omap_musb_mailbox function that some PHY drivers are using.
Let's fix the issue by exporting a more generic musb_mailbox function
from the MUSB core and allow platform glue layers to register phy_callback
function as needed.
And now we can now also get rid of the include/linux/musb-omap.h.

MUSB currently breaks badly if we try to build in support
for multiple platforms. This also happens if done as loadable
modules, which is not nice for distros.
Let's fix the issue by adding new struct musb_io for the IO
access functions that the platform code can populate. Note
that we don't want to use the current ops as that's really
platform_data and and set as a const.
This should allow eventually adding function pointers also

different set of patches. For now, let's just fix the PIO

Eventually it gaves up and the device remains dead:

It seems that since we got woken up via MUSB_INTR_RESUME the

until the glue layer resumed then I don't see this problem.
I also move musb_host_resume_root_hub() into that callback since I don't

Currently, resume and reset is completed when the USB core calls back
the root hub, asking for the port's state. This results in
unpredictable timing of state assertion, which in turn renders some
USB devices unusable after resume.
Fix this by moving the logic to end the reset and suspend state out of
musb_hub_control() into separate functions called from delayed workers.
GetPortStatus only reports the current state now, without taking any
real action.
The rh_timeout variable is kept in order to define a minimum time gap
between reset and resume only.
FWIW, in my case, a Verbatim "STORE N GO" mass storage device won't
resume cleanly without this patch.

I have am335x-evm with one port running in OTG mode. Since commit
fe4cb09 ("usb: musb: gadget: remove hcd initialization") the loaded
gadget does non pop up on the host. All I see is
|usb 4-5: new high-speed USB device number 52 using ehci-pci
|usb 4-5: device descriptor read/64, error -110
Since a later commit 2cc65fe ("usb: musb: add musb_host_setup() and
musb_host_cleanup()) the gadget shows up on the host again but only
in OTG mode (because we have the host init code running). It does not
work in device only mode.
If running in OTG mode and the gadget is removed and added back (rmmod
followed by modprobe of a gadget) then the same error is pops up on the
host side.
This patch ensures that the gadget side also executes musb_start() which
puts the chip in "connect accept" mode. With this change the device
works in OTG & device mode and the gadget can be added & removed
multiple times.
A device (if musb is in OTG mode acting as a host) is only recognized if
it is attached during module load (musb_hdrc module). After the device
unplugged and plugged again the host does not recognize it. We get a
buch of errors if musb running in OTG mode, attached to a host and no
gadget is loaded. Bah.
This is one step forward. Host & device only mode should work. I will
look at OTG later. I looked at this before commit fe4cb09 and OTG wasn't
working there perfectly so I am not sure that it is a regression :)

DMA mode 1 data corruption anomaly on Blackfin systems. This issue is
specific to the Blackfin silicon as the bug appears to be related to the
connection of the musb ip to the bus/dma fabric.
Data corruption when using USB DMA mode 1. (Issue manager 17-01-0105)
DMA mode 1 allows large size transfers to generate a single interrupt
at the end of the entire transfer. The transfer is split up in packets
of length specified in the Maximum Packet Size field for that endpoint.
If the transfer size is not an integer multiple of the Maximum Packet
Size, a short packet will be present at the end of the transfer.
Under certain conditions this packet may be corrupted in the USB FIFO.
Workaround:
Use DMA mode 1 to transfer (n* Maximum Packet Size) and schedule DMA
mode 0 to transfer the short packet.
As an example if your transfer size is 33168 bytes and Maximum Packet
Size equals 512, schedule [33168 - (33168 mod 512)] in DMA mode 1 and
the remainder (33168 mod 512) in DMA mode 0.
