This makes linux/gpio.h mainly a wrapper for the consumer interface. There is one more possible follow-up that I did not include here: As there are only around 350 files[1] remaining that actually use the legacy interfaces, we could rename linux/gpio.h to e.g. linux/gpio/legacy.h, and leave linux/gpio.h as an alias for linux/gpio/consumer.h until we remove it entirely. Arnd Changes since v1: - incorporate feedback from Geert Uytterhoeven - remove asm-generic/gpio.h - drop legacy export interface and a few other functions - stop including linux/gpio/driver.h Arnd Bergmann (8): gpiolib: remove irq_to_gpio() definition gpiolib: remove empty asm/gpio.h files gpiolib: coldfire: remove custom asm/gpio.h gpiolib: remove asm-generic/gpio.h gpiolib: shrink further gpiolib: remove legacy gpio_export gpiolib: remove gpio_to_chip gpiolib: split linux/gpio/driver.h out of linux/gpio.h Documentation/admin-guide/gpio/sysfs.rst | 2 +- .../driver-api/driver-model/devres.rst | 1 - Documentation/driver-api/gpio/legacy.rst | 52 +----- Documentation/translations/zh_CN/gpio.txt | 26 --- Documentation/translations/zh_TW/gpio.txt | 27 --- arch/arm/Kconfig | 1 - arch/arm/include/asm/gpio.h | 22 --- arch/arm/mach-davinci/board-dm646x-evm.c | 28 +-- arch/arm/mach-omap1/irq.c | 1 + arch/arm/mach-omap2/pdata-quirks.c | 9 +- arch/arm/mach-orion5x/board-rd88f5182.c | 1 + arch/arm/mach-pxa/lubbock.c | 2 +- arch/arm/mach-s3c/mach-h1940.c | 1 + arch/arm/mach-s3c/s3c64xx.c | 1 + arch/arm/mach-sa1100/assabet.c | 1 + arch/arm/plat-orion/gpio.c | 1 + arch/m68k/Kconfig.cpu | 1 - arch/m68k/include/asm/gpio.h | 102 ----------- arch/m68k/include/asm/mcfgpio.h | 2 +- arch/sh/Kconfig | 1 - arch/sh/boards/board-magicpanelr2.c | 1 + arch/sh/boards/mach-ap325rxa/setup.c | 7 +- arch/sh/include/asm/gpio.h | 50 ----- drivers/gpio/Kconfig | 8 - drivers/gpio/gpio-davinci.c | 3 +- drivers/gpio/gpio-ucb1400.c | 1 + drivers/gpio/gpiolib-devres.c | 25 --- drivers/gpio/gpiolib-sysfs.c | 4 +- drivers/input/touchscreen/ads7846.c | 3 +- drivers/media/i2c/noon010pc30.c | 5 +- drivers/media/i2c/ov9650.c | 4 +- drivers/media/i2c/s5k4ecgx.c | 3 +- drivers/media/pci/sta2x11/sta2x11_vip.c | 10 +- drivers/mfd/dm355evm_msp.c | 3 +- drivers/mfd/htc-i2cpld.c | 1 + drivers/mfd/ucb1400_core.c | 1 + drivers/net/ieee802154/ca8210.c | 3 +- .../broadcom/brcm80211/brcmsmac/led.c | 1 + drivers/pinctrl/core.c | 5 +- drivers/soc/fsl/qe/gpio.c | 4 +- include/asm-generic/gpio.h | 172 ------------------ include/linux/bcma/bcma_driver_chipcommon.h | 2 +- include/linux/gpio.h | 123 +++++++------ include/linux/mfd/ucb1x00.h | 1 + include/linux/ucb1400.h | 1 + 45 files changed, 133 insertions(+), 590 deletions(-) delete mode 100644 arch/arm/include/asm/gpio.h delete mode 100644 arch/m68k/include/asm/gpio.h delete mode 100644 arch/sh/include/asm/gpio.h delete mode 100644 include/asm-generic/gpio.h
