xhci: Don't enable/disable RWE on bus suspend/resume.

2013-11-13T03:08:06+00:00

commit f217c980ca980e3a645b7485ea5eae9a747f4945 upstream.

The RWE bit of the USB 2.0 PORTPMSC register is supposed to enable
remote wakeup for devices in the lower power link state L1.  It has
nothing to do with the device suspend remote wakeup from L2.  The RWE
bit is designed to be set once (when USB 2.0 LPM is enabled for the
port) and cleared only when USB 2.0 LPM is disabled for the port.

The xHCI bus suspend method was setting the RWE bit erroneously, and the
bus resume method was clearing it.  The xHCI 1.0 specification with
errata up to Aug 12, 2012 says in section 4.23.5.1.1.1 "Hardware
Controlled LPM":

"While Hardware USB2 LPM is enabled, software shall not modify the
HIRDBESL or RWE fields of the USB2 PORTPMSC register..."

If we have previously enabled USB 2.0 LPM for a device, that means when
the USB 2.0 bus is resumed, we violate the xHCI specification by
clearing RWE.  It also means that after a bus resume, the host would
think remote wakeup is disabled from L1 for ports with USB 2.0 Link PM
enabled, which is not what we want.

This patch should be backported to kernels as old as 3.2, that
contain the commit 65580b4321eb36f16ae8b5987bfa1bb948fc5112 "xHCI: set
USB2 hardware LPM".  That was the first kernel that supported USB 2.0
Link PM.

usb-storage: add quirk for mandatory READ_CAPACITY_16

2013-11-13T03:08:06+00:00

commit 32c37fc30c52508711ea6a108cfd5855b8a07176 upstream.

Some USB drive enclosures do not correctly report an
overflow condition if they hold a drive with a capacity
over 2TB and are confronted with a READ_CAPACITY_10.
They answer with their capacity modulo 2TB.
The generic layer cannot cope with that. It must be told
to use READ_CAPACITY_16 from the beginning.

usb: musb: start musb on the udc side, too

2013-11-13T03:08:06+00:00

commit 001dd84a92a25f8f2bad7d26df8bdb0362302c07 upstream.

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 :)
