2015-12-21phy: ti-pipe3: introduce local struct device* in probeKishon Vijay Abraham I1-27/+27
No functional change. Introduce local struct device pointer in probe and replace using &pdev->dev/phy->dev with the local device pointer. This is in preparation to split ti_pipe3_probe and add separate functions for getting mem resource, getting sysctrl and getting clocks. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

2015-12-20phy: rockchip-usb: expose the phy-internal PLLsHeiko Stuebner1-27/+161
The USB phys on Rockchip SoCs contain their own internal PLLs to create the 480MHz needed. Additionally this PLL output is also fed back into the core clock-controller as possible source for clocks like the GPU or others. Until now this was modelled incorrectly with a "virtual" factor clock in the clock controller. The one big caveat is that if we turn off the usb phy via the siddq signal, all analog components get turned off, including the PLLs. It is therefore possible that a source clock gets disabled without the clock driver ever knowing, possibly making the system hang. Therefore register the phy-plls as real clocks that the clock driver can then reference again normally, making the clock hirarchy finally reflect the actual hardware. The phy-ops get converted to simply turning that new clock on and off which in turn controls the siddq signal of the phy. Through this the driver gains handling for platform-specific data, to handle the phy->clock name association.

2015-12-16usb: musb: core: Fix handling of the phy notificationsTony Lindgren1-16/+16
We currently can't unload omap2430 MUSB platform glue driver module and this cause issues for fixing the MUSB code further. The reason we can't remove omap2430 is because it uses the PHY functions and also exports the omap_musb_mailbox function that some PHY drivers are using. Let's fix the issue by exporting a more generic musb_mailbox function from the MUSB core and allow platform glue layers to register phy_callback function as needed. And now we can now also get rid of the include/linux/musb-omap.h.

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.

2015-08-10phy: lpc18xx-usb-otg: fix clock order in phy initJoachim Eastwood1-3/+3
Changing the frequency of the USB clock must be done before the PLL is powered on (prepared). This matters when the USB clock is not setup by either boot ROM or boot loader. Reorder the function calls to adhere to the order noted in the user manual. Signed-off-by: Joachim Eastwood <manabian@gmail.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

2015-08-01phy: ti-pipe3: i783 workaround for SATA lockup after dpll unlock/relockRoger Quadros1-6/+55
SATA_PLL_SOFT_RESET bit of CTRL_CORE_SMA_SW_0 must be toggled between a SATA DPLL unlock and re-lock to prevent SATA lockup. Introduce a new DT parameter 'syscon-pllreset' to provide the syscon regmap access to this register which sits in the control module. If the register is not provided we fallback to the old behaviour i.e. SATA DPLL refclk will not be disabled and we prevent SoC low power states.
