This patch adds support for TPS68470 GPIOs. There are 7 GPIOs and a few sensor related GPIOs. These GPIOs can be requested and configured as appropriate. The GPIOs are also provided with descriptive names.

2017-08-14gpio: vf610: add imx7ulp supportDong Aisheng
The Rapid General-Purpose Input and Output with 2 Ports (RGPIO2P) on MX7ULP is similar to GPIO on Vibrid. But unlike Vibrid, the RGPIO2P has an extra Port Data Direction Register (PDDR) used to configure the individual port pins for input or output. We introduce a bool have_paddr with fsl_gpio_soc_data data to distinguish this differences. And we support getting the output status by checking the GPIO direction in PDDR.

2017-08-14gpio: rcar: add gen[123] fallback compatibility stringsSimon Horman
Add fallback compatibility string for R-Car Gen 1, 2 and 3. In the case of Renesas R-Car hardware we know that there are generations of SoCs, f.e. Gen 1 and 2. But beyond that its not clear what the relationship between IP blocks might be. For example, I believe that r8a7790 is older than r8a7791 but that doesn't imply that the latter is a descendant of the former or vice versa. We can, however, by examining the documentation and behaviour of the hardware at run-time observe that the current driver implementation appears to be compatible with the IP blocks on SoCs within a given generation. For the above reasons and convenience when enabling new SoCs a per-generation fallback compatibility string scheme being adopted for drivers for Renesas SoCs. Also deprecate renesas,gpio-rcar as its name is more generic than its implementation.

2017-08-14gpiolib: allow gpio irqchip to map irqs dynamicallyGrygorii Strashko
Now IRQ mappings are always created for all (allowed) GPIOs in gpiochip in gpiochip_irqchip_add_key() which goes against the idea of SPARSE_IRQ and, as result, leads to: - increasing of memory consumption for IRQ descriptors most of which will never ever be used (espessially on platform with a high number of GPIOs). (sizeof(struct irq_desc) == 256 on my tested platforms) - imposibility to use GPIO irqchip APIs by gpio drivers when HW implements GPIO IRQ functionality as IRQ crossbar/router which has only limited number of IRQ outputs (example from [1], all GPIOs can be mapped on only 8 IRQs). Hence, remove static IRQ mapping code from gpiochip_irqchip_add_key() and instead replace irq_find_mapping() with irq_create_mapping() in gpiochip_to_irq(). Also add additional gpiochip_irqchip_irq_valid() calls in gpiochip_to_irq() and gpiochip_irq_map(). After this change gpio2irq mapping will happen the following way when GPIO irqchip APIs are used by gpio driver: - IRQ mappings will be created statically if driver passes first_irq>0 vlaue in gpiochip_irqchip_add_key(). - IRQ mappings will be created dynamically from gpio_to_irq() or of_irq_get(). Tested on am335x-evm and dra72-evm-revc. - dra72-evm-revc: number of created irq mappings decreased from 402 -> 135 Mem savings 267*256 = 68352 (66kB) - am335x-evm: number of created irq mappings decreased from 188 -> 63 Mem savings 125*256 = 32000 (31kB) [1] https://lkml.org/lkml/2017/6/15/428 Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2017-08-14gpio: reject invalid gpio before getting gpio_descMasami Hiramatsu
Check user-given gpio number and reject it before calling gpio_to_desc() because gpio_to_desc() is for kernel driver and it expects given gpio number is valid (means 0 to 511). If given number is invalid, gpio_to_desc() calls WARN() and dump registers and stack for debug. This means user can easily kick WARN() just by writing invalid gpio number (e.g. 512) to /sys/class/gpio/export.

Core: - Export add/remove for lookup tables so that modules can export GPIO descriptor tables. - Handle GPIO sleep states: it is now possible to flag that a GPIO line may loose its state during suspend/resume of the system to save power. This is used in the Wolfson Micro Arizona driver. - ACPI-based GPIO was tightened up a lot around the edges. - Use bitmap_fill() to speed up a loop. New drivers: - Exar XRA1403 SPI-based GPIO. - MVEBU driver now supports Armada 7K and 8K. - LP87565 PMIC GPIO. - Renesas R-CAR R8A7743 (RZ/G1M). - The new IOT2040 8250 serial/GPIO also comes in through this changeset. Substantial driver changes: - Seriously fix the Exar 8250 GPIO portions to work. - The MCP23S08 was moved out to a pin control driver. - Convert MEVEBU to use regmap for register access. - Drop Vulcan support from the Broadcom driver. - Serious cleanup and improvement of the mockup driver, giving us a better test coverage. Misc: - Lots of janitorial clean up. - A bunch of documentation fixes" * tag 'gpio-v4.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (70 commits) serial: exar: Add support for IOT2040 device gpio-exar/8250-exar: Make set of exported GPIOs configurable platform: Accept const properties serial: exar: Factor out platform hooks gpio-exar/8250-exar: Rearrange gpiochip parenthood gpio: exar: Fix iomap request gpio-exar/8250-exar: Do not even instantiate a GPIO device for Commtech cards serial: uapi: Add support for bus termination gpio: rcar: Add R8A7743 (RZ/G1M) support gpio: gpio-wcove: Fix GPIO control register offset calculation gpio: lp87565: Add support for GPIO gpio: dwapb: fix missing first irq for edgeboth irq type MAINTAINERS: Take maintainership for GPIO ACPI support gpio: exar: Fix reading of directions and values gpio: exar: Allocate resources on behalf of the platform device gpio-exar/8250-exar: Fix passing in of parent PCI device gpio: mockup: use devm_kcalloc() where applicable gpio: mockup: add myself as author gpio: mockup: improve the error message gpio: mockup: don't return magic numbers from probe() ...

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "This is the big bulk of pin control changes for the v4.13 series: Core: - The documentation is moved over to RST. - We now have agreed bindings for enabling input and output buffers without actually enabling input and/or output on a pin. We are chiseling out some details of pin control electronics. New drivers: - ZTE ZX - Renesas RZA1 - MIPS Ingenic JZ47xx: also switch over existing drivers in the tree to use this pin controller and consolidate earlier spread out code. - Microschip MCP23S08: this driver is migrated from the GPIO subsystem and totally rewritten to use proper pin control. All users are switched over. New subdrivers: - Renesas R8A7743 and R8A7745. - Allwinner Sunxi A83T R_PIO. - Marvell MVEBU Armada CP110 and AP806. - Intel Cannon Lake PCH. - Qualcomm IPQ8074. Notable improvements: - IRQ support on the Marvell MVEBU Armada 37xx. - Meson driver supports HDMI CEC, AO, I2S, SPDIF and PWM. - Rockchip driver now supports iomux-route switching for RK3228, RK3328 and RK3399. - Rockchip A10 and A20 are merged into a single driver. - STM32 has improved GPIO support. - Samsung Exynos drivers are split per ARMv7 and ARMv8. - Marvell MVEBU is converted to use regmap for register access. Maintenance: - Several Renesas SH-PFC refactorings and updates. - Serious code size cut for Mediatek MT7623. - Misc janitorial and MAINTAINERS fixes" * tag 'pinctrl-v4.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (137 commits) pinctrl: samsung: Remove bogus irq_[un]mask from resource management pinctrl: rza1: make structures rza1_gpiochip_template and rza1_pinmux_ops static pinctrl: rza1: Remove unneeded wrong check for wrong variable pinctrl: qcom: Add ipq8074 pinctrl driver pinctrl: freescale: imx7d: make of_device_ids const. pinctrl: DT: extend the pinmux property to support integers array pinctrl: generic: Add output-enable property pinctrl: armada-37xx: Fix number of pin in sdio_sb pinctrl: armada-37xx: Fix uart2 group selection register mask pinctrl: bcm2835: Avoid warning from __irq_do_set_handler pinctrl: sh-pfc: r8a7795: Add PWM support MAINTAINERS: Add Qualcomm pinctrl drivers section arm: dts: dt-bindings: Add Renesas RZ/A1 pinctrl header dt-bindings: pinctrl: Add RZ/A1 bindings doc pinctrl: Renesas RZ/A1 pin and gpio controller pinctrl: sh-pfc: r8a7792: Add SCIF1 and SCIF2 pin groups pinctrl.txt: move it to the driver-api book pinctrl: ingenic: checking for NULL instead of IS_ERR() pinctrl: uniphier: fix WARN_ON() of pingroups dump on LD20 pinctrl: uniphier: fix WARN_ON() of pingroups dump on LD11 ...

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core updates from Greg KH: "Here is the big driver core update for 4.13-rc1. The large majority of this is a lot of cleanup of old fields in the driver core structures and their remaining usages in random drivers. All of those fixes have been reviewed by the various subsystem maintainers. There's also some small firmware updates in here, a new kobject uevent api interface that makes userspace interaction easier, and a few other minor things. All of these have been in linux-next for a long while with no reported issues" * tag 'driver-core-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (56 commits) arm: mach-rpc: ecard: fix build error zram: convert remaining CLASS_ATTR() to CLASS_ATTR_RO() driver-core: remove struct bus_type.dev_attrs powerpc: vio_cmo: use dev_groups and not dev_attrs for bus_type powerpc: vio: use dev_groups and not dev_attrs for bus_type USB: usbip: convert to use DRIVER_ATTR_RW s390: drivers: convert to use DRIVER_ATTR_RO/WO platform: thinkpad_acpi: convert to use DRIVER_ATTR_RO/RW pcmcia: ds: convert to use DRIVER_ATTR_RO wireless: ipw2x00: convert to use DRIVER_ATTR_RW net: ehea: convert to use DRIVER_ATTR_RO net: caif: convert to use DRIVER_ATTR_RO TTY: hvc: convert to use DRIVER_ATTR_RW PCI: pci-driver: convert to use DRIVER_ATTR_WO IB: nes: convert to use DRIVER_ATTR_RW HID: hid-core: convert to use DRIVER_ATTR_RO and drv_groups arm: ecard: fix dev_groups patch typo tty: serdev: use dev_groups and not dev_attrs for bus_type sparc: vio: use dev_groups and not dev_attrs for bus_type hid: intel-ish-hid: use dev_groups and not dev_attrs for bus_type ...
