* | phy: qcom-ufs: add ufs phy type selectionGilad Broner2016-03-22
| | | | | | | | | | | | | | | | | | | | | | | | Currently both 14nm phy and 20nm phy are compiled and built into the kernel, while only one type is actually present and used. Add a choice selection to the kernel configuration to specify which phy type shall be used.

* | phy: qcom-ufs-qmp-14nm: add workaround to program tuned VCO codeSubhash Jadavani2016-03-22
| | | | | | | | | | | | | | | | | | | | | | | | On some UFS PHY HW revisions, UFS PHY power up calibration sequence requires manual VCO tuning code and its better to rely on the VCO tuning code programmed by boot loader. This change enables the quirk to program the manually tuned VCO code.

* | phy: qcom-ufs-qmp-14nm: add PHY initialization workaroundSubhash Jadavani2016-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | UFS PHY auto calibration is not working currently hence add workaround to have manual calibrated configuration as part of power up sequence itself. We had another workaround for hibern8 enter/exit to work and it had required us to save the auto calibrated VCO codes after PHY power up sequence and then set the PHY PLL in VCO bypass mode. As the auto calibration is not working and we are already having manually calibrated VCO codes as part of PHY power up sequence itself, this change removes the old workaround.

| | | | | | | | | | | | | | | | | | To power collapse UFS PHY, we need to write 0 to UFS_PHY_POWER_DOWN_CONTROL register but instead we are writing 1 to it. This change fixes this issue. Change-Id: Ib12226bd3adefb2d5848aa6e7c20ae0263865148 Signed-off-by: Subhash Jadavani <subhashj@codeaurora.org>

| | | | | | | | | | | | | | | | | | | | | | UFS_PHY_RX_PWM_GEAR_BAND configuration is changed after the power up sequence so make sure that this register gets set to power on reset value during power up sequence. This is required in case power up sequence is initiated after this register value got changed to value other than power on reset value.

* | phy: qcom-ufs-qmp-14nm: add hibern8 workaroundSubhash Jadavani2016-03-22
| | | | | | | | | | | | | | | | | | | | | | | | Due to missing reset in the UFS PHY logic, the pll may not lock following analog power collapse. As a result the common block of the PHY must be put into reset during hibernate entry and taken out of reset during hibernate exit. SW needs to save ave the calibrated VCO codes after the PHY power up sequence is completed, saving these codes will save substantial time on hibernate exit (<50us vs. 1.7ms).

* | phy: qcom-ufs-qmp-14nm: add svs mode workaroundSubhash Jadavani2016-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UFS PHY power up calibration sequence on UFS controller revision 2.0.0 can't have SVS mode configuration otherwise calibration result cannot be used in HS-G3. So there are additional register writes must be done after the PHY is initialized but before the controller requests hibernate exit. Also as this issue is not present on UFS controller revision 2.1.0, SVS mode configuration registers are written as part of the power up calibration sequence itself. This change takes care of these issues related to SVS mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases link startup fails due to unexpected termination caused by DIF-N to DIF-Z transition. This patch will make PHY look only for DIF-N -> DIF-P transition and not respond to DIF-N to DIF-Z transition. Hence prevents a case where DIF-Z is identified as DIF-P, which may result in unexpected LCC interpretation and PHY switch to HS.

It made the phy dependent on the ufs unipro which is unnecessary binding. This change moves the decision into the ufs driver, and pass it through a function parameter to the calibration routine in the phy driver.

* | phy: ufs-qcom: disable RX LineCfgSubhash Jadavani2016-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some UFS devices send incorrect LineCfg data as part of power mode change sequence which may cause host PHY to go into bad state. Currently we workaround this issue by disabling the device's TX LCC but disabling TX LCC is much more complicated if both host and device supports UniPro 1.6 specification. To simplify the workaround, this change disables the host PHY's RX LineCfg to skip processing incorrect LineCfg from device.

* | scsi: ufs-qcom: add support to control the device ref_clkSubhash Jadavani2016-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Qualcomm platforms, there will be many consumers of the source clock which also supply ref_clk to UFS Device. So even if generic UFS driver (ufshcd) vote to turn off the source ref_clk, it's very likely that device ref_clk is still running. Hence some of the qualcomm chipsets have separate control bit to gate & ungate the UFS ref_clk to device. This control bit is part of the TLMM register adddress space so it can't be simulated at clock control bit which means UFS qcom driver has to manually control this bit to gate or ungate the device ref_clk. This change adds support for the same.

* | phy: relocate and rename phy ufs filesYaniv Gardi2016-03-22
|/ | | | | | | | | | | | | | | | | | | | | | | | | This change contains: 1. Relocating the phy ufs files to reside under the phy driver since this is the location of any file that implements the APIs presented in the generic phy framework 2. Renaming ufs-msm-phy*.* files to be phy-qcom-ufs*.* files. Since UFS is not used strictly in a specific set of targets but rather its code is applicable to MSM, APQ, IPQ etc, any mentioning of "msm" in the file name should be changed to "qcom". Also, prefix of "phy-" is the naming convention of platform driver files that reside in the phy driver. 3. As a result of the relocation of files into the phy driver, a new path is created (include/linux/scsi/ufs) and there we expose ufs header files that are being used also from the drivers/scsi/ufs and from drivers/phy as well.

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.
