locking/atomics, cmpxchg: Privatize the inclusion of asm/cmpxchg.h

2015-09-13T08:35:46+00:00

After commit:

  654672d4ba1a ("locking/atomics: Add _{acquire|release|relaxed}() variants of some atomic operations")

Architectures may only provide {cmp,}xchg_relaxed definitions in
asm/cmpxchg.h. Other variants, such as {cmp,}xchg, may be built in
linux/atomic.h, which means simply including asm/cmpxchg.h may not get
the definitions of all the{cmp,}xchg variants.

Therefore, we should privatize the inclusions of asm/cmpxchg.h to
keep it only included in arch/* and replace the inclusions outside
with linux/atomic.h

phy: Constify struct phy_ops variables

2015-08-03T13:05:09+00:00

The phy_ops variables are never modified after initialized in these
drivers, so make them const.

Merge 4.1-rc7 into usb-next

2015-06-08T17:57:51+00:00

This resolves a merge issue in musb_core.c and we want the fixes that
were in Linus's tree in this branch as well for testing.

phy: phy-rcar-gen2: Fix USBHS_UGSTS_LOCK value

2015-05-12T15:27:19+00:00

According to the technical update (No. TN-RCS-B011A/E), the UGSTS LOCK
bit location is bit 8, not bits 1 and 0. It also says that the register
address offset of UGSTS is 0x88, not 0x90.
So, this patch fixes the USBHS_UGSTS_LOCK value and some comments.

This is a common checking in various drivers, so move the checking to
_of_phy_get().

phy: Renesas R-Car Gen2 PHY driver

2014-09-24T09:48:31+00:00

This PHY, though formally being a part of Renesas USBHS controller, contains the
UGCTRL2 register that controls multiplexing of the USB ports (Renesas calls them
channels) to the different USB controllers: channel 0 can be connected to either
PCI EHCI/OHCI or USBHS controllers, channel 2 can be connected to PCI EHCI/OHCI
or xHCI controllers.

This is a new driver for this USB PHY currently already supported under drivers/
usb/phy/. The reason for writing the new driver was the requirement that the
multiplexing  of USB channels to the controller be dynamic, depending on what
USB drivers  are loaded,  rather than static as provided by the old driver. The
infrastructure provided by drivers/phy/phy-core.c  seems to fit that purpose
ideally. The new driver only  supports device tree probing  for now.
