git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of the GPIO changes for the v4.14 cycle. Not so much changes this time, phew. David Daney and Bartosz Golaszewski did all the really interesting work in infrastructure improvement across GPIO and IRQ core, hats off for them and to tglx and Marc Z for general help with these patch sets. Core changes: - Allow the GPIO irqchip to allocate IRQs dynamically. This is an important change on systems where only a restricted number of IRQs, lesser than the number of GPIO lines, can be utilized. Now we can allocate these on a first-come-first-served basis instead of hogging up valuable IRQ lines. - Serious fix-up of the kerneldoc documentation and inclusion into the kerneldoc builds. - Pulled in the IRQ simulator from the IRQ core tree and use this in the GPIO mockup driver for exhaustive testing of interrupt abilities. New drivers: - New driver for ThunderX and OCTEON-TX. This is especially interesting as it picks up improvements from the IRQ core that allow us to handle fasteoi ACKs upwards in a hierarchy when there are IRQ flag latches on several levels in a hierarchy. Very interesting work here. - New subdriver for Renesas R-Car r8a7745 (RZ/G1E). Misc: - Several fixes and improvements for Xilinx Zynq GPIO. - Support an enablement GPIO for the 74x164 GPIO. - Switch a bunch of chips to use devres to allocate irq descriptors. - A bunch of constification fixes" * tag 'gpio-v4.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (63 commits) gpio: mockup: remove unused variable gc gpio: pl061: constify amba_id Revert "gpiolib: request the gpio before querying its direction" gpio: twl6040: remove unneeded forward declaration gpio: zevio: make gpio_chip const gpio: add gpio_add_lookup_tables() to add several tables at once gpio: rcar: Add r8a7745 (RZ/G1E) support gpio: brcmstb: check return value of gpiochip_irqchip_add() MAINTAINERS: Add entry for THUNDERX GPIO Driver. gpio: Add gpio driver support for ThunderX and OCTEON-TX gpio: mockup: use irq_sim gpio: mxs: use devres for irq generic chip gpio: mxc: use devres for irq generic chip gpio: pch: use devres for irq generic chip gpio: ml-ioh: use devres for irq generic chip gpio: sta2x11: use devres for irq generic chip gpio: sta2x11: disallow unbinding the driver gpio: mxs: disallow unbinding the driver gpio: mxc: disallow unbinding the driver gpio: aspeed: Remove reference to clock name in debounce warning message ...

2017-08-14gpio: Add support for TPS68470 GPIOsRajmohan Mani3-0/+192
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 Aisheng1-3/+44
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.
