usb: chipidea: add host role

This adds EHCI host support to the chipidea driver. We want it to be
part of the hdrc driver and not a standalone (sub-)driver module, as
the structure of ehci-hcd.c suggests, so for chipidea controller we
hack it to not provide platform-related code, but only the ehci hcd.

The ehci-platform driver won't work for us here too, because the
controller uses the same registers for both device and host mode and
also otg-related bits, so it's not really possible to put ehci registers
into a separate resource.

This is not a pretty solution, but the alternative is exporting symbols
from the chipidea driver to a ehci-chipidea driver and doing all the
module refcounting.

usb: gadget: ci13xxx: rename register layouts

Currently, the register prefixes in the driver seem to be mixed: the
capability registers are the ones that contain capability information,
such as number of hardware endpoints, while the registers that are
used to program the controller are called operational registers.

Normally, capability registers start at 0x100 offset of the register
window and are followed by operational registers. In some versions,
however, capability registers start at 0x0 offset.

This patch renames the register and adjusts their offsets appropriately,
leaving the possibility of having a non-standard capability offset.

I couldn't find any mentions of the TESTMODE register anywhere, so I
suspect it might only be enabled in chipidea internal versions of the

are now filled in by the usb-serial core during driver registration,

The same is true of the one remaining no_dynamic_id entry.

This patch (as1550) fixes a bug in the usb-serial core that affects
the ftdi_sio driver and most likely others as well.  The core
implements suspend and resume routines, but it doesn't store pointers
to those routines in the usb_driver structures that it registers,
even though it does set those drivers' supports_autosuspend flag.  The
end result is that when one of these devices is autosuspended, we try
to call through a NULL pointer.

The patch fixes the problem by setting the suspend and resume method
pointers to the appropriate routines in the USB serial core, along
with the supports_autosuspend field, in each driver as it is
registered.

This pull request contains one workaround for a Silicon
Issue found on all RTL releases prior to 2.20a, which
would cause a metastability state on Run/Stop bit.

We also have some patches implementing a few extra Standard
requests introduced by USB3 spec (Set SEL and Set Isoch Delay),
as well as one patch, which has been pending for a long time,
implementing LPM support.

Last, but not least, we are splitting the host address space
out of the dwc3 core driver otherwise xHCI won't be able to
request_mem_region() its own address space. This patch is
only needed because we are (as we should) re-using the xHCI
driver, which is a completely separate module.

Together with these three big changes, come a few extra preparatory
patches which most move code around, define macros and so on, as
well as a fix for Isochronous transfers which hasn't been triggered
before.

This pull request is quite big, but mainly because there's a
giant rework of the s3c_hsotg.c driver to make it friendlier
for other users. Samsung Exynos platforms use the DesignWare
Core USB2 IP from Synopsys so it's a bit unfair to have the
driver work for Samsung platforms only. In short, the big
rework is in preparation to make the driver more reusable.

Another big rework in this pull request came from Ido, where
he's removing the redundant pointer for the endpoint descriptor
from the controller driver's own endpoint representation. The
same pointer is available through the generic struct usb_ep
structure.

Also on this pull request is the conversion of a few extra
controller drivers to the new style registration, which allows
multiple controllers to be available on the same platform and
helps remove global pointers from those drivers.

Together with those big changes, there's the usual fixes and cleanups
to gadget drivers. Nothing major.

thus can never be zero. Hence the 'then' branch was never executed and
the timer never deleted.

This did not matter until commit 5dd5bc40f3b6 ("TTY: pdc_cons, use

never happened due to the bug above.

So change the test to really trigger at the last close by changing the
condition to 'tty->count == 1'.

Well, the driver should not touch tty->count at all.  It should use
tty_port->count and count open count there itself.

init: don't try mounting device as nfs root unless type fully matches

Currently, we'll try mounting any device who's major device number is
UNNAMED_MAJOR as NFS root.  This would happen for non-NFS devices as
well (such as 9p devices) but it wouldn't cause any issues since
mounting the device as NFS would fail quickly and the code proceeded to
doing the proper mount:

       [  101.522716] VFS: Unable to mount root fs via NFS, trying floppy.
       [  101.534499] VFS: Mounted root (9p filesystem) on device 0:18.

Commit 6829a048102a ("NFS: Retry mounting NFSROOT") introduced retries
when mounting NFS root, which means that now we don't immediately fail
and instead it takes an additional 90+ seconds until we stop retrying,
which has revealed the issue this patch fixes.

This meant that it would take an additional 90 seconds to boot when
we're not using a device type which gets detected in order before NFS.

This patch modifies the NFS type check to require device type to be
'Root_NFS' instead of requiring the device to have an UNNAMED_MAJOR
major.  This makes boot process cleaner since we now won't go through
the NFS mounting code at all when the device isn't an NFS root
("/dev/nfs").

Lin Ming [Mon, 23 Apr 2012 01:03:49 +0000 (09:03 +0800)]
ACPI: Fix D3hot v D3cold confusion

Before this patch, ACPI_STATE_D3 incorrectly referenced D3hot
in some places, but D3cold in other places.

After this patch, ACPI_STATE_D3 always means ACPI_STATE_D3_COLD;
and all references to D3hot use ACPI_STATE_D3_HOT.

ACPI's _PR3 method is used to enter both D3hot and D3cold states.
What distinguishes D3hot from D3cold is the presence _PR3
(Power Resources for D3hot)  If these resources are all ON,
then the state is D3hot.  If _PR3 is not present,
or all _PR0 resources for the devices are OFF,
then the state is D3cold.

This patch applies after Linux-3.4-rc1.
A future syntax cleanup may remove ACPI_STATE_D3
to emphasize that it always means ACPI_STATE_D3_COLD.

hfsplus: Fix potential buffer overflows

Commit ec81aecb2966 ("hfs: fix a potential buffer overflow") fixed a few
potential buffer overflows in the hfs filesystem.  But as Timo Warns
pointed out, these changes also need to be made on the hfsplus
filesystem as well.

USB: EHCI: OMAP: Finish ehci omap phy reset cycle before adding hcd.

'ARM: OMAP3: USB: Fix the EHCI ULPI PHY reset issue' (1fcb57d0f) created a regression
with Beagleboard xM if booting the kernel after running 'usb start' under u-boot.

Finishing the reset before calling 'usb_add_hcd' fixes the regression. This is most likely due to
usb_add_hcd calling the driver's reset and init functions which expect the hardware to be
up and running.
