From: Thierry Reding <treding@xxxxxxxxxx> Hi Linus, here's a first draft of patches to make GPIOLIB_IRQCHIP flexible enough to support the Tegra186 use-case. Instead of just fixing the bugs that I had pointed out earlier, this goes one step further and completely integrates IRQ chip registration into GPIO chip registration. The idea is that drivers will initialize a set of fields (collected in a new struct gpio_irq_chip) before calling gpiochip_add() (or derivatives) and gpiolib will internally set up an IRQ domain and register the IRQ chip. Currently this makes use of the new infrastructure only in the Tegra186 driver, but I plan to convert a couple of others once we can agree that this is a direction that you're comfortable with. Thierry Thierry Reding (12): gpio: Use unsigned int for interrupt numbers gpio: Implement tighter IRQ chip integration gpio: Move irq_nested into struct gpio_irq_chip gpio: Move irqdomain into struct gpio_irq_chip gpio: Move irqchip into struct gpio_irq_chip gpio: Move irq_valid_mask into struct gpio_irq_chip gpio: Move lock_key into struct gpio_irq_chip gpio: Move irq_chained_parent to struct gpio_irq_chip gpio: Move irq_default_type to struct gpio_irq_chip gpio: Move irq_handler to struct gpio_irq_chip gpio: Move irq_base to struct gpio_irq_chip gpio: Add Tegra186 support Documentation/gpio/driver.txt | 6 +- drivers/bcma/driver_gpio.c | 2 +- drivers/gpio/Kconfig | 9 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-104-dio-48e.c | 2 +- drivers/gpio/gpio-104-idi-48.c | 2 +- drivers/gpio/gpio-104-idio-16.c | 2 +- drivers/gpio/gpio-adnp.c | 2 +- drivers/gpio/gpio-altera.c | 4 +- drivers/gpio/gpio-aspeed.c | 6 +- drivers/gpio/gpio-ath79.c | 2 +- drivers/gpio/gpio-brcmstb.c | 2 +- drivers/gpio/gpio-crystalcove.c | 2 +- drivers/gpio/gpio-dln2.c | 2 +- drivers/gpio/gpio-ftgpio010.c | 2 +- drivers/gpio/gpio-intel-mid.c | 2 +- drivers/gpio/gpio-lynxpoint.c | 2 +- drivers/gpio/gpio-max732x.c | 2 +- drivers/gpio/gpio-mcp23s08.c | 2 +- drivers/gpio/gpio-merrifield.c | 2 +- drivers/gpio/gpio-mockup.c | 10 +- drivers/gpio/gpio-omap.c | 2 +- drivers/gpio/gpio-pca953x.c | 2 +- drivers/gpio/gpio-pcf857x.c | 2 +- drivers/gpio/gpio-pci-idio-16.c | 2 +- drivers/gpio/gpio-pl061.c | 2 +- drivers/gpio/gpio-rcar.c | 2 +- drivers/gpio/gpio-reg.c | 4 +- drivers/gpio/gpio-stmpe.c | 6 +- drivers/gpio/gpio-tc3589x.c | 2 +- drivers/gpio/gpio-tegra186.c | 625 +++++++++++++++++++++++++++++ drivers/gpio/gpio-vf610.c | 2 +- drivers/gpio/gpio-wcove.c | 2 +- drivers/gpio/gpio-ws16c48.c | 2 +- drivers/gpio/gpio-xgene-sb.c | 2 +- drivers/gpio/gpio-xlp.c | 2 +- drivers/gpio/gpio-zx.c | 2 +- drivers/gpio/gpio-zynq.c | 2 +- drivers/gpio/gpiolib.c | 232 ++++++++--- drivers/pinctrl/bcm/pinctrl-bcm2835.c | 4 +- drivers/pinctrl/bcm/pinctrl-iproc-gpio.c | 2 +- drivers/pinctrl/intel/pinctrl-baytrail.c | 6 +- drivers/pinctrl/intel/pinctrl-cherryview.c | 6 +- drivers/pinctrl/intel/pinctrl-intel.c | 2 +- drivers/pinctrl/nomadik/pinctrl-nomadik.c | 4 +- drivers/pinctrl/pinctrl-amd.c | 2 +- drivers/pinctrl/pinctrl-at91.c | 2 +- drivers/pinctrl/pinctrl-coh901.c | 2 +- drivers/pinctrl/pinctrl-oxnas.c | 2 +- drivers/pinctrl/pinctrl-pic32.c | 2 +- drivers/pinctrl/pinctrl-pistachio.c | 2 +- drivers/pinctrl/pinctrl-st.c | 2 +- drivers/pinctrl/pinctrl-sx150x.c | 2 +- drivers/pinctrl/qcom/pinctrl-msm.c | 2 +- drivers/pinctrl/sirf/pinctrl-atlas7.c | 2 +- drivers/pinctrl/sirf/pinctrl-sirf.c | 2 +- drivers/pinctrl/spear/pinctrl-plgpio.c | 2 +- include/linux/gpio/driver.h | 81 ++-- 58 files changed, 943 insertions(+), 147 deletions(-) create mode 100644 drivers/gpio/gpio-tegra186.c -- 2.12.0 -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
