usb: phy: Find the right match in devm_usb_phy_match

2015-05-06T19:59:11+00:00

commit 869aee0f31429fa9d94d5aef539602b73ae0cf4b upstream.

The res parameter passed to devm_usb_phy_match() is the location where the
pointer to the usb_phy is stored, hence it needs to be dereferenced before
comparing to the match data in order to find the correct match.

usb: phy: return -ENODEV on failure of try_module_get

2014-11-14T17:00:03+00:00

commit 2c4e3dbf63b39d44a291db70016c718f45d9cd46 upstream.

When __usb_find_phy_dev() does not return error and
try_module_get() fails, return -ENODEV.

usb: phy: tegra: Avoid use of sizeof(void)

2014-10-05T21:52:14+00:00

commit 9ce9ec95fb9b82e09b55a52f1bb8a362bf8f74d8 upstream.

The PHY configuration is stored in an opaque "config" field, but when
allocating the structure, its proper size needs to be known. In the case
of UTMI, the proper structure is tegra_utmip_config of which a local
variable already exists, so we can use that to obtain the size from.

Fixes the following warning from the sparse checker:

	drivers/usb/phy/phy-tegra-usb.c:882:17: warning: expression using sizeof(void)

ARM: OMAP: replace checks for CONFIG_USB_GADGET_OMAP

2014-07-01T03:11:53+00:00

commit 77c2f02edbeda9409a7cf3fd66233015820c213a upstream.

Commit 193ab2a60700 ("usb: gadget: allow multiple gadgets to be built")
apparently required that checks for CONFIG_USB_GADGET_OMAP would be
replaced with checks for CONFIG_USB_OMAP. Do so now for the remaining
checks for CONFIG_USB_GADGET_OMAP, even though these checks have
basically been broken since v3.1.

And, since we're touching this code, use the IS_ENABLED() macro, so
things will now (hopefully) also work if USB_OMAP is modular.

usb: phy: am335x-control: wait 1ms after power-up transitions

2014-05-06T14:59:33+00:00

commit a31a942a148e0083ce560ffeb54fb60e06ab7201 upstream.

Tests have shown that when a power-up transition is followed by other
PHY operations too quickly, the USB port appears dead. Waiting 1ms fixes
this problem.

usb: phy: msm: fix compilation errors when !CONFIG_PM_SLEEP

2014-02-20T15:17:24+00:00

Both the PM_RUNTIME and PM_SLEEP callbacks call into the common
msm_otg_{suspend,resume} routines, however these routines are only being
built when CONFIG_PM_SLEEP.  In addition, msm_otg_{suspend,resume} also
depends on msm_hsusb_config_vddcx(), which is only built when
CONFIG_PM_SLEEP.

Fix the CONFIG_PM_RUNTIME, !CONFIG_PM_SLEEP case by changing the
preprocessor conditional, and moving msm_hsusb_config_vddcx().

While we're here, eliminate the CONFIG_PM conditional for setting
up the dev_pm_ops.

This address the following errors Russell King has hit doing randconfig
builds:

drivers/usb/phy/phy-msm-usb.c: In function 'msm_otg_runtime_suspend':
drivers/usb/phy/phy-msm-usb.c:1691:2: error: implicit declaration of function 'msm_otg_suspend'

usb: phy: move some error messages to debug

2014-02-04T20:59:14+00:00

the PHY layer is supposed to be optional,
considering some PHY have no control bus
for SW to poke around.

After commit 1ae5799 (usb: hcd: Initialize
USB phy if needed) any HCD which didn't provide
a PHY driver would emit annoying error messages.

In this patch we're decreasing those messages
to debugging only and we also add a PHY prefix
or use dev_dbg so we know where they're coming from.

Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2014-01-24T02:49:36+00:00

Pull ARM driver updates from Olof Johansson:
 "Updates of SoC-near drivers and other driver updates that makes more
  sense to take through our tree.

  The largest part of this is a conversion of device registration for
  some renesas shmobile/sh devices over to use resources.  This has
  required coordination with the corresponding arch/sh changes, and
  we've agreed to merge the arch/sh changes through our tree.

  Added in this branch is support for Trusted Foundations secure
  firmware, which is what is used on many of the commercial Nvidia Tegra
  products that are in the market, including the Nvidia Shield.  The
  code is local to arch/arm at this time since it's uncertain whether it
  will be shared with arm64 longer-term, if needed we will refactor
  later.

  A couple of new RTC drivers used on ARM boards, merged through our
  tree on request by the RTC maintainer.

  ... plus a bunch of smaller updates across the board, gpio conversions
  for davinci, etc"
