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 v4.9 series: Subsystem improvements: - do away with the last users of the obsolete Kconfig options ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB (the latter always sounded like an item on a wishlist to Santa Claus to me). We can now select GPIOLIB and be done with it, for all archs. After some struggle it even work on UM. Not that it has GPIO, but if it wants to, it can select the library. - continued efforts to make drivers properly either tristate or bool. - introduce a warning for drivers assigning default triggers to their irqchip lines when probed from device tree, so we find and fix these ambigous drivers. It is agreed that in the OF config path, the device tree defines trigger characteristics. - the same warning, mutatis mutandis, for ACPI-probed GPIO irqchips. - we introduce the ability to mark certain IRQ lines as "unusable" as they can be taken by BIOS/firmware, unrouted in silicon and generally nasty if you use them, and such things. This is put to good use in the STMPE driver and also in the Cherryview pin control driver. - a new "mockup" virtual GPIO device that can be used for testing. The plan is to add unit tests under tools/* for exercising this device and verify that the kernel code paths are working as they should. - make memory-mapped I/O-drivers depend on HAS_IOMEM. This was implicit all the time, but when people started building UM with allyesconfig or allmodconfig it exploded in their face. - move some stray bits of device tree and ACPI HW description callbacks down into their respective implementation silo. These were causing issues when compiling on !HAS_IOMEM as well, so now eventually UM compiles the GPIOLIB library if it wants to. New drivers: - new driver for the Aspeed GPIO front-end companion to the pin controller merged through the pin control tree. - new driver for the LP873x PMIC GPIO portions. - new driver for Technologic Systems' I2C FPGA GPIO such as TS4900, TS-7970, TS-7990 and TS-4100. - new driver for the Broadcom BCM63xx series including BCM6338 and BCM6345. - new driver for the Intel WhiskeyCove PMIC GPIO. - new driver for the Allwinner AXP209 PMIC GPIO portions. - new driver for Diamond Systems 48 line GPIO-MM, another of these port-mapped I/O expansion cards. - support the STMicroelectronics STMPE1600 variant in the STMPE driver. Driver improvements: - the STMPE driver now supports rising/falling edge detection properly for IRQs. - the PCA954x will now fetch and enable its VCC regulator properly. - major rework of the PCA953x driver with the goal of eventually switching it over to use regmap and thus modernize it even more. - switch the IOP driver to use the generic MMIO GPIO library. - move the ages old HTC EGPIO (extended GPIO) GPIO expander driver over to this subsystem from MFD, achieveing some separation of concerns" * tag 'gpio-v4.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (81 commits) gpio: add missing static inline gpio: OF: localize some gpiochip init functions gpio: acpi: separation of concerns gpio: OF: separation of concerns gpio: make memory-mapped drivers depend on HAS_IOMEM gpio: stmpe: use BIT() macro gpio: stmpe: forbid unused lines to be mapped as IRQs mfd/gpio: Move HTC GPIO driver to GPIO subsystem gpio: MAINTAINERS: Add an entry for GPIO mockup driver gpio/mockup: add virtual gpio device gpio: Added zynq specific check for special pins on bank zero gpio: axp209: Implement get_direction gpio: aspeed: remove redundant return value check gpio: loongson1: remove redundant return value check ARM: omap2: fix missing include gpio: tc3589x: fix up complaints on unsigned gpio: tc3589x: add .get_direction() and small cleanup gpio: f7188x: use gpiochip_get_data instead of container_of gpio: tps65218: use devm_gpiochip_add_data() for gpio registration gpio: aspeed: fix return value check in aspeed_gpio_probe() ...

2016-10-04mfd: arizona: Handle probe deferral for reset GPIOCharles Keepax1-4/+9
The Arizona CODECs will generally function correctly without a reset line although it is strongly advised to have one, as such we do allow the system to boot if the reset gpio is missing or incorrectly specified. However we should fail probe if we get a probe deferral request, this patch adds handling for this case.

2016-10-04mfd: ab8500-debugfs: Prevent initialised field from being over-writtenLee Jones1-29/+21
Due to the lack of parity in the way array fields have been named/ numbered, a mistake was made where more debug fields were declared than actually existed. In doing so, 2 fields were added, which although unclear, were already declared in the array. The result was that the latter declarations trashed the former ones. This patch places the array back in the correct order and removes the offending NULL entries. While we're at it, let's ensure this doesn't happen again by naming each field properly and add a new *_LAST define to describe how many fields there should be.

2016-10-04mfd: arizona: Use suspend_noirq inplace of suspend_lateCharles Keepax1-6/+4
As runtime PM doesn't function whilst processing system suspend/resume operations and the Arizona IRQ handlers need runtime PM to function we must disable IRQs during these operations. Whilst this is already done in the driver we are using suspend/suspend_late and resume/resume_noirq to do so which has two problems. Firstly, as suspend_late is before suspend_noirq that means we still have a small window where an IRQ can cause issues. Secondly, if another suspend_late handler fails after ours has run then (as resume_noirq will not run) we will make unbalanced calls to enable_irq. This is all simply fixed by using the suspend_noirq callback rather than suspend_late. Whilst we are doing this tidy the code up a little, and use the appropriate helper macros.

There are some cases in arizona_dev_init, such as where we don't recognise the chip ID, in which we head to the error path without setting a sensible error code in ret. This would lead to the chip silently failing probe, as it would still return 0. Fix this up by adding appropriate sets of the return value.

2016-10-04mfd: da9053: Ensure the FAULT_LOG is cleared during MFD driver probeSteve Twiss1-0/+51
The function da9052_clear_fault_log() is added to mitigate the case of persistent data being transferred between reboots. Clearance of any the persistent information within the DA9053 FAULT_LOG register must be completed during start-up so the fault-log does not continue with previous values. A clearance function has been added here in the kernel driver because wiping the fault-log cannot be counted on outside the Linux kernel.

2016-10-04mfd: rtsx_usb: Avoid setting ucr->current_sg.statusLu Baolu1-5/+5
Member "status" of struct usb_sg_request is managed by usb core. A spin lock is used to serialize the change of it. The driver could check the value of req->status, but should avoid changing it without the hold of the spinlock. Otherwise, it could cause race or error in usb core. This patch could be backported to stable kernels with version later than v3.14.

probe_irq_on() only returns non-zero if it found any interrupts below IRQ32 which could be probe candidates. If all the probable interrupts are higher than 32, then this will cause a failure.

2016-10-04mfd: qcom_rpm: Handle message RAM clockLinus Walleij1-0/+20
The MSM8660, APQ8060, IPQ806x and MSM8960 have a GCC clock to the message RAM used by the RPM. This needs to be enabled for messages to pass through. This is a crude solution that simply prepare/enable at probe() and disable/unprepare at remove(). More elaborate PM is probably possible to add later. The construction uses IS_ERR() to gracefully handle the platforms that do not provide a message RAM clock. It will bail out of probe only if the clock is hitting a probe deferral situation. Of course this requires the proper device tree set-up: rpm: rpm@104000 { compatible = "qcom,rpm-msm8660"; clocks = <&gcc RPM_MSG_RAM_H_CLK>; clock-names = "ram"; ... }; I have provided this in the MSM8660 device tree, and will provide patches for the other targets.
