e7e42b9d2a ARM: OMAP4+: Remove unused omap_l3_noc platform init
Omap4 and later have been booting in device tree only
mode for quite some time now. This initcall is no longer
needed. Note that omap3 uses a different driver omap_l3_smx,
and the initcall for that one is still needed until omap3
boots in device tree only mode.

32f638fc11 PCI: Don't oops on virtual buses in acpi_pci_get_bridge_handle()
acpi_pci_get_bridge_handle() returns the ACPI handle for the bridge device
(either a host bridge or a PCI-to-PCI bridge) leading to a PCI bus.  But
SR-IOV virtual functions can be on a virtual bus with no bridge leading to
it.  Return a NULL acpi_handle in this case instead of trying to
dereference the NULL pointer to the bridge.

This fixes a NULL pointer dereference oops in pci_get_hp_params() when
adding SR-IOV VF devices on virtual buses.

60ba032ed7 ACPI / property: Drop size_prop from acpi_dev_get_property_reference()
The size_prop argument of the recently added function
acpi_dev_get_property_reference() is not used by the only current
caller of that function and is very unlikely to be used at any time
going forward.

Namely, for a property whose value is a list of items each containing
a references to a device object possibly accompanied by some integers,
the number of items in the list can always be computed as the number
of elements of type ACPI_TYPE_LOCAL_REFERENCE in the property package.
Thus it should never be necessary to provide an additional "cells"
property with a value equal to the number of items in that list.  It
also should never be necessary to provide a "cells" property specifying
how many integers are supposed to be following each reference.

For this reason, drop the size_prop argument from
acpi_dev_get_property_reference() and update its caller accordingly.

6e58ed578e usb: gadget: f_midi: enable use of the index parameter
The soundcard index to use for the ALSA device creation is passed as a
parameter to f_midi_bind_config(), but is assigned to midi->index only
after the call to f_midi_register_card(midi). So no matter what is passed
to f_midi_bind_config(), the actual index for snd_card_new() is always 0.
This probably works ok if at the moment of f_midi's bind there are no
other snd_cards, but if there are, it is not possible to bind f_midi.

This patch moves the assignment to a place before the call to
f_midi_register_card(midi).

baadd52f0a usb: musb: try a race-free wakeup
Attaching a keyboard, using it as a wakeup via

|do
|	echo enabled > $f

going into standby

and now a wake up by a pressing a key.
What happens is that the system wakes up but the USB device is dead. The
USB stack tries to send a few control URBs but nothing comes back.
Eventually it gaves up and the device remains dead:

It seems that since we got woken up via MUSB_INTR_RESUME the
musb_host_finish_resume() callback is executed before the
resume-callbacks of the PHY and glue layer are invoked. If I delay it
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
see any reason in doing anything resume-link if there are still pieces
not restored.

b87fd2f7aa usb: musb: core: check link status on resume
The am335x-evmsk support two kinds of suspend:
- standby
  the USB device remains powered while the system goes into suspend

- mem
  the USB device becomes powerless while the system goes into suspend.

In the "standby" case the device resumes quickly. In the "mem" case the
system hangs for a few seconds. It seems to me that the USB-device has
no address (it was disconnected) and the USB stack thinks that it is
fully operational and GetPortStatus returns the status from before the
suspend so it is not a big help here.

This adds a check in the resume path to see if the device mode (A or B)
and the speed is the same. If the device went missing between
suspend/resume (VBUS went down) then MUSB seems to go into B mode and
HS/FS bits are cleared. In that case we clear the port1_status bits and
assume a disconnect. Once the stack learns this it does a "logical
disconnect" and removes the USB-device quickly. Should the device remain
connected during the suspend then MUSB will receives a "CONNECT" interrupt.

b4c9f578cb usb: dwc3: exynos: remove non-DT support for Exynos Specific Glue layer
DWC3 Exynos Specific Glue layer can be used only for Exynos SoCs.
In addition, non-DT for EXYNOS SoCs is not supported from v3.11;
thus, there is no need to support non-DT for DWC3 Exynos Specific
Glue layer.

The 'linux/platform_data/dwc3-exynos.h' file has been used for
non-DT support. Thus, the 'dwc3-exynos.h' file is removed, because
it is not used anymore.

cdeb794313 usb: renesas_usbhs: fix usbhs_pipe_clear() for DCP PIPE
Since the DCPCTR doesn't have the ACLRM bit, the usbus_pipe_clear()
should not call the usbhsp_pipectrl_set() with ACLRM.
So, this patch fixes this issue to add the usbhs_fifo_clear_dcp()
in fifo.c because the controller needs the CFIFO to clear the
the DCP PIPE.

4ef35b10bf usb: renesas_usbhs: fix the timing of dcp_control_transfer_done
According to the datasheet, this driver should clear the INTSTS0.CTRT
bit before this controller detects the next stage transition. Otherwise,
the driver may not be able to clear the bit after the controller went to
the next stage transition. After that, the driver will not be able to
clear the INTSTS0.VALID, and a usb control transfer will not finish
finally.

If we use the testusb tool, it is easy to reproduce this issue:

 # testusb -a -t 10

Since the previous code handled a data stage and a status stage in
the usbhsf_pio_try_push(), it may not clear the INTSTS0.CTRT at the
right timing.
So, this patch change the timing of usbhs_dcp_control_transfer_done()
to the usbhsg_irq_ctrl_stage().

This patch fixes an issue that this driver always enable the D+ pullup
after it detected the VBUS connection even though this usb controller
can control the D+ pullup timing by software. So, this driver should
enable the D+ pullup after a gadget driver called usb_gadget_connect().

11432050f0 usb: renesas_usbhs: gadget: fix NULL pointer dereference in ep_disable()
This patch fixes an issue that the NULL pointer dereference happens
when we uses g_audio driver. Since the g_audio driver will call
usb_ep_disable() in afunc_set_alt() before it calls usb_ep_enable(),
the uep->pipe of renesas usbhs driver will be NULL. So, this patch
adds a condition to avoid the oops.
