USB: EHCI: fix build error in ehci-mxc

2013-01-23T19:27:08+00:00

This patch (as1643b) fixes a build error in ehci-hcd when compiling for
ARM with allmodconfig:

drivers/usb/host/ehci-hcd.c:1285:0: warning: "PLATFORM_DRIVER" redefined [enabled by default]
drivers/usb/host/ehci-hcd.c:1255:0: note: this is the location of the previous definition
drivers/usb/host/ehci-mxc.c:280:31: warning: 'ehci_mxc_driver' defined but not used [-Wunused-variable]
drivers/usb/host/ehci-hcd.c:1285:0: warning: "PLATFORM_DRIVER" redefined [enabled by default]
drivers/usb/host/ehci-hcd.c:1255:0: note: this is the location of the previous definition

The fix is to convert ehci-mxc over to the new "ehci-hcd is a library"
scheme so that it can coexist peacefully with the ehci-platform
driver.  As part of the conversion the ehci_mxc_priv data structure,
which was allocated dynamically, is now placed where it belongs: in
the private area at the end of struct ehci_hcd.

USB: EHCI: add a name for the platform-private field

2013-01-22T17:22:13+00:00

This patch (as1642) adds an ehci->priv field for private use by EHCI
platform drivers.  The space was provided some time ago, but it didn't
have a name.

Until now none of the platform drivers has used this private space,
but that's about to change in the next patch of this series.

USB: EHCI: fix incorrect configuration test

2013-01-22T17:21:23+00:00

This patch (as1641) fixes a minor bug in ehci-hcd left over from when
the Chipidea driver was converted to the "ehci-hcd is a library"
scheme.  The test for whether the Chipidea platform driver is active
should be IS_ENABLED(), not defined().

USB: EHCI: Move definition of EHCI_STATS to ehci.h

2013-01-22T17:21:23+00:00

Without this, platform drivers e.g. ehci-omap.c will see a
different version of struct ehci_hcd than ehci-hcd.c and
break reference to 'debug_dir' and 'priv' members when
CONFIG_USB_DEBUG is enabled.

USB: UHCI: fix IRQ race during initialization

2013-01-22T16:55:13+00:00

This patch (as1644) fixes a race that occurs during startup in
uhci-hcd.  If the IRQ line is shared with other devices, it's possible
for the handler routine to be called before the data structures are
fully initialized.

The problem is fixed by adding a check to the IRQ handler routine.  If
the initialization hasn't finished yet, the routine will return
immediately.

  usb: fixes for v3.8-rc5

  Finally we have a build fix for fsl-mxc-udc UDC driver.

  We also have a fix for ep0 maxburst setting on DWC3
  which could confuse the HW if we tell it we had way
  too many streams on that endpoint when it _has_ to be
  only one.

  cppi_dma support for MUSB got a fix when running as a
  module. By dropping the wrong __init annotation, the
  function will be available even when we're modules and
  we're done with .init.text section.

  Last, but not least, we have a fix on FunctionFS which
  was causing a bug on our option parsing algorithm.

usb: gadget: FunctionFS: Fix missing braces in parse_opts

2013-01-18T12:11:11+00:00

Add missing braces around an if block in ffs_fs_parse_opts. This broke
parsing the uid/gid mount options and causes mount to fail when using
uid/gid. This has been introduced by commit b9b73f7c (userns: Convert usb
functionfs to use kuid/kgid where appropriate) in 3.7.

usb: dwc3: gadget: fix ep->maxburst for ep0

2013-01-18T12:11:00+00:00

dwc3_gadget_set_ep_config expects maxburst as incremented by 1. So, by
default initialize ep->maxburst to 1 for ep0.

usb: gadget: fsl_mxc_udc: replace MX35_IO_ADDRESS to ioremap

2013-01-18T12:08:21+00:00

As mach/hardware.h is deleted, we can't visit platform code at driver.
It has no phy driver to combine with this controller, so it has to use
ioremap to map phy address as a workaround.

usb: gadget: fsl-mxc-udc: replace cpu_is_xxx() with platform_device_id

2013-01-18T12:08:20+00:00

As mach/hardware.h is deleted, we need to use platform_device_id to
differentiate SoCs. Besides, one cpu_is_mx35 is useless as it has
already used pdata to differentiate runtime

Meanwhile we update the platform code accordingly.
