I'll fix up stuff. > Should it be using "mcp->chip.dev->of_node" instead? Or should the > driver just depend on OF? The former I think, the driver has only optional DT support. I will fix up and send a new pull request when finished. Maybe I should not have the of_node inside #ifdef CONFIG_OF in the gpio_chip and just keep it around like we do in struct device, that makes for less #ifdef clutter.

Hi Linus, here is the bulk of GPIO changes for the v3.19 kernel series. The major external change is the new API to driver several GPIOs simultaneously, and the major internal change is that we're getting rid of a static array of GPIO descriptors and again moving away, slowly, from the global GPIO numberspace. There is a patch hitting the TTY/serial subsystem, it has been ACKed by Greg. More details in the signed tag as usual. Please pull it in! Yours, Linus Walleij The following changes since commit f114040e3ea6e07372334ade75d1ee0775c355e1: Linux 3.18-rc1 (2014-10-19 18:08:38 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git tags/gpio-v3.19-1 for you to fetch changes up to 256965d724347a9fa1cce42dc30987e7d92addb3: gpio: pl061: document gpio-ranges property for bindings file (2014-12-03 14:46:27 +0100) ---------------------------------------------------------------- This is the bulk of GPIO changes for the v3.19 series: - A new API that allows setting more than one GPIO at the time. This is implemented for the new descriptor-based API only and makes it possible to e.g. toggle a clock and data line at the same time, if the hardware can do this with a single register write. Both consumers and drivers need new calls, and the core will fall back to driving individual lines where needed. Implemented for the MPC8xxx driver initially. - Patched the mdio-mux-gpio and the serial mctrl driver that drives modems to use the new multiple-setting API to set several signals simultaneously. - Get rid of the global GPIO descriptor array, and instead allocate descriptors dynamically for each GPIO on a certain GPIO chip. This moves us closer to getting rid of the limitation of using the global, static GPIO numberspace. - New driver and device tree bindings for 74xx ICs. - New driver and device tree bindings for the VF610 Vybrid. - Support the RCAR r8a7793 and r8a7794. - Guidelines for GPIO device tree bindings trying to get things a bit more strict with the advent of combined device properties. - Suspend/resume support for the MVEBU driver. - A slew of minor fixes and improvements. ---------------------------------------------------------------- Alexander Shiyan (2): GPIO: Add driver for 74xx-ICs with MMIO access GPIO: 74xx-mmio: Add DT bindings documentation Alexander Stein (4): gpio: mcp23s08: Do not free unrequested interrupt gpio: mcp23s08: request a shared interrupt gpio: mcp23s08: Add simple IRQ support for SPI devices gpio: mcp23s08: Add option to configure IRQ output polarity as active high Alexandre Courbot (5): gpio: rename gpio_lock_as_irq to gpiochip_lock_as_irq Documentation: gpio: guidelines for bindings gpio: remove gpio_descs global array gpio: remove const modifier from gpiod_get_direction() gpio: fix deferred probe detection for legacy API Daniel Thompson (1): gpio: msm-v1: Fix typo in function argument Geert Uytterhoeven (2): gpio: Check if base is positive before calling gpio_is_valid() gpio: em: Use dynamic allocation of GPIOs Hisashi Nakamura (1): gpio: rcar: Add r8a7793 and r8a7794 support Janusz Uzycki (1): gpio: mxs: implement get_direction callback Linus Walleij (1): gpio: dwapb: fix compile errors Pramod Gurav (3): gpio: cs5535: Switch to using managed resources with devm_ gpio: amd8111: unmap ioport on failure case gpio: grgpio: remove irq_domain resources on failure Rojhalat Ibrahim (4): gpiolib: allow simultaneous setting of multiple GPIO outputs gpio-mpc8xxx: add mpc8xxx_gpio_set_multiple function mdio-mux-gpio: Use GPIO descriptor interface and new gpiod_set_array function serial: mctrl_gpio: use gpiod_set_array function Stefan Agner (2): gpio: vf610: add gpiolib/IRQ chip driver for Vybrid Documentation: dts: add bindings for Vybrid GPIO/PORT module Thomas Petazzoni (1): gpio: mvebu: add suspend/resume support Varka Bhadram (3): gpio: gpio-stp-xway: remove duplicate check on resource gpio: gpio-tb10x: remove duplicate check on resource gpio: gpio-davinci: remove duplicate check on resource Yunlei He (2): gpio: pl061: hook request if gpio-ranges avaiable gpio: pl061: document gpio-ranges property for bindings file .../devicetree/bindings/gpio/gpio-74xx-mmio.txt | 30 +++ .../devicetree/bindings/gpio/gpio-mcp23s08.txt | 2 + .../devicetree/bindings/gpio/gpio-vf610.txt | 55 ++++ Documentation/devicetree/bindings/gpio/gpio.txt | 40 ++- .../devicetree/bindings/gpio/pl061-gpio.txt | 2 +- .../devicetree/bindings/gpio/renesas,gpio-rcar.txt | 4 +- Documentation/gpio/consumer.txt | 27 ++ Documentation/gpio/driver.txt | 4 +- drivers/gpio/Kconfig | 23 ++ drivers/gpio/Makefile | 2 + drivers/gpio/gpio-74xx-mmio.c | 170 ++++++++++++ drivers/gpio/gpio-amd8111.c | 1 + drivers/gpio/gpio-bcm-kona.c | 4 +- drivers/gpio/gpio-cs5535.c | 11 +- drivers/gpio/gpio-davinci.c | 5 - drivers/gpio/gpio-dwapb.c | 4 +- drivers/gpio/gpio-em.c | 11 +- drivers/gpio/gpio-grgpio.c | 1 + drivers/gpio/gpio-mcp23s08.c | 40 ++- drivers/gpio/gpio-mpc8xxx.c | 27 ++ drivers/gpio/gpio-msm-v1.c | 2 +- drivers/gpio/gpio-mvebu.c | 99 +++++++ drivers/gpio/gpio-mxs.c | 13 + drivers/gpio/gpio-omap.c | 2 +- drivers/gpio/gpio-pl061.c | 20 +- drivers/gpio/gpio-rcar.c | 27 +- drivers/gpio/gpio-stp-xway.c | 8 +- drivers/gpio/gpio-tb10x.c | 7 +- drivers/gpio/gpio-tegra.c | 4 +- drivers/gpio/gpio-vf610.c | 295 +++++++++++++++++++++ drivers/gpio/gpio-vr41xx.c | 4 +- drivers/gpio/gpiolib-acpi.c | 6 +- drivers/gpio/gpiolib-legacy.c | 12 +- drivers/gpio/gpiolib-sysfs.c | 6 +- drivers/gpio/gpiolib.c | 241 +++++++++++++++-- drivers/net/phy/mdio-mux-gpio.c | 37 +-- drivers/pinctrl/pinctrl-at91.c | 4 +- drivers/pinctrl/samsung/pinctrl-exynos.c | 4 +- drivers/pinctrl/sunxi/pinctrl-sunxi.c | 6 +- drivers/tty/serial/serial_mctrl_gpio.c | 12 +- include/linux/gpio.h | 7 +- include/linux/gpio/consumer.h | 40 ++- include/linux/gpio/driver.h | 8 +- 43 files changed, 1165 insertions(+), 162 deletions(-) create mode 100644 Documentation/devicetree/bindings/gpio/gpio-74xx-mmio.txt create mode 100644 Documentation/devicetree/bindings/gpio/gpio-vf610.txt create mode 100644 drivers/gpio/gpio-74xx-mmio.c create mode 100644 drivers/gpio/gpio-vf610.c -- To unsubscribe from this list: send the line "unsubscribe linux-gpio" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
