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.

2015-09-04Merge tag 'gpio-v4.3-1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.3 kernel cycle. There is quite a lot going on in the GPIO subsystem this merge window, so the main matter is decribed below. The hits in other subsystems when making the GPIO flags optional are all ACKed by their respective subsystem maintainers. Core changes: - Root out the wrapper devm_gpiod_get() and gpiod_get() etc versions of the descriptor calls that did not use the flags argument on the end. This was around for too long and eventually Uwe Kleine-König took the time to clean it out and the last users are removed along with the macros in this tag. In several cases the use of flags simplifies the code. For this reason we have (ACKed) patches hitting in DRM, IIO, media, NFC, USB+PHY up until we hammer in the nail with removing the macros. - Add a fat document describing how much ready-made GPIO stuff we have i the kernel to discourage people from reinventing a square wheel in userspace, as so often happens. - Create a separate lockdep class for each instance of a GPIO IRQ chip instead of using one class for all chips, as the current code will not work with systems with several GPIO chips doing lockdep debugging. - Protect against driver unloading also when a GPIO line is only used as IRQ for the GPIOLIB_IRQCHIP helpers. - If the GPIO chip has no designated owner, assign the parent device driver owner as owner. - Consolidation of chained IRQ handler install/remove replacing all call sites where irq_set_handler_data() and irq_set_chained_handler() were done in succession with a combined call to irq_set_chained_handler_and_data(). This series was created by Thomas Gleixner after the problem was observed by Russell King. - Tglx also made another series of patches switching __irq_set_handler_locked() for irq_set_handler_locked() which is way cleaner. - Tglx and Jiang Liu wrote a good bunch of patches to make use of irq_desc_get_xxx() accessors and avoid looking up irq_descs from IRQ numbers. The goal is to get rid of the irq number from the handlers in the IRQ flow which is nice. - Rob Herring killed off the set_irq_flags() for all GPIO drivers. This was an ARM specific function that is replaced with the generic irq_modify_status() where special flags are actually needed. - When an OF node has a pin range for its GPIOs, return -EPROBE_DEFER if the pin controller isn't available. Pretty logical, yet needed to be fixed. - If a driver using GPIOLIB_IRQCHIP has its own irq_*_resources call back, then call these instead of the defaults provided by the GPIOLIB. - Fix an undocumented ABI hole: named GPIOs were not properly documented. Driver improvements: - Add get_direction() support to the generic GPIO driver, it's strange that we didn't have that before. - Make it possible to have input-only GPIO chips using the generic GPIO driver. - Clean out platform data support from the Emma Mobile (EM) driver - Finegrained runtime PM support for the RCAR driver. - Support r8a7795 (R-car H3) in the RCAR driver. - Support interrupts on GPIOs 16 thru 31 in the DaVinci driver. - Some consolidation and new support in the MPC8xxx driver, we now support MPC5125. - Preempt-RT-friendly patches: the OMAP, MPC8xxx, drivers uses raw spinlocks making it work better with the realime patches. - Interrupt support for the EXTRAXFS GPIO driver. - Make the ETRAXFS GPIO driver support also ARTPEC-3. - Interrupt and wakeup support for the BRCMSTB driver, also for wakeup from S5 cold boot. - Mask MXC IRQs during suspend. - Improve OMAP2 GPIO set_debounce() to work according to spec. - The VF610 driver handles IRQs properly.

2015-07-25phy-sun4i-usb: Swap check for disconnect thresholdHans de Goede
Before this commit the code for determining the disconnect threshold was checking for "allwinner,sun4i-a10-usb-phy" or "allwinner,sun6i-a31-usb-phy" assuming that those where the exception and then newer SoCs would use a disconnect threshold of 2 like sun7i does. But it turns out that newer SoCs use a disconnect threshold of 3 and sun5i and sun7i are the exceptions, so check for those instead. Here are the settings from the various Allwinner SDK sources: sun4i-a10: USBC_Phy_Write(usbc_no, 0x2a, 3, 2); sun5i-a13: USBC_Phy_Write(usbc_no, 0x2a, 2, 2); sun6i-a31: USBC_Phy_Write(usbc_no, 0x2a, 3, 2); sun7i-a20: USBC_Phy_Write(usbc_no, 0x2a, 2, 2); sun8i-a23: USBC_Phy_Write(usbc_no, 0x2a, 3, 2); sun8i-h3: USBC_Phy_Write(usbc_no, 0x2a, 3, 2); sun9i-a80: USBC_Phy_Write(usbc_no, 0x2a, 3, 2); Note this commit makes no functional changes as currently we only support sun4i - sun7i.

2015-07-25phy-sun4i-usb: Add extcon support for the otg phy (phy0)Hans de Goede
The sunxi musb glue needs to know if a host or normal usb cable is plugged in, add extcon support so that the musb glue can monitor the host status.

2015-07-25phy-sun4i-usb: Add id and vbus detection support for the otg phy (phy0)Hans de Goede
The usb0 phy is connected to an OTG controller, and as such needs some special handling: 1) It allows explicit control over the pullups, enable these on phy_init and disable them on phy_exit. 2) It has bits to signal id and vbus detect to the musb-core, add support for for monitoring id and vbus detect gpio-s for use in dual role mode, and set these bits to the correct values for operating in host only mode when no gpios are specified in the devicetree. While updating the devicetree binding documentation also add documentation for the sofar undocumented usage of regulators for vbus for all 3 phys.

2015-07-25phy: add lpc18xx usb otg phy driverJoachim Eastwood
Add PHY driver for the internal USB OTG PHY found on NXP LPC18xx and LPC43xx devices. This driver takes care of enabling the PHY in CREG (syscon) and setting the required clock frequency. Signed-off-by: Joachim Eastwood <manabian@gmail.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
2015-07-15phy: berlin-usb: fix divider for BG2Thomas Hebb
The USB PLL divider set by the marvell,berlin2-usb-phy compatible is not correct for BG2. We couldn't change it before because BG2Q incorrectly used the same compatible string. Now that BG2Q's compatible is fixed, change BG2's divider to the correct value.

2015-07-15phy: ti-pipe3: fix suspendRoger Quadros
Relying on PM-ops for shutting down PHY clocks was a bad idea since the users (e.g. PCIe/SATA) might not have been suspended by then. The main culprit for not shutting down the clocks was the stray pm_runtime_get() call in probe. Fix the whole thing in the right way by getting rid of that pm_runtime_get() call from probe and removing all PM-ops. It is the sole responsibility of the PHY user to properly turn OFF and de-initialize the PHY as part of its suspend routine. As PHY core serializes init/exit we don't need to use a spinlock in this driver. So get rid of it.

2015-07-06phy: tusb1210: make better use of gpiod APIUwe Kleine-König
Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Furthermore there is devm_gpiod_get_optional which is designed to get optional gpios. Simplify driver accordingly. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
