      "message": "gpio: sysfs interface\n\nThis adds a simple sysfs interface for GPIOs.\n\n    /sys/class/gpio\n    \t/export ... asks the kernel to export a GPIO to userspace\n    \t/unexport ... to return a GPIO to the kernel\n        /gpioN ... for each exported GPIO #N\n\t    /value ... always readable, writes fail for input GPIOs\n\t    /direction ... r/w as: in, out (default low); write high, low\n\t/gpiochipN ... for each gpiochip; #N is its first GPIO\n\t    /base ... (r/o) same as N\n\t    /label ... (r/o) descriptive, not necessarily unique\n\t    /ngpio ... (r/o) number of GPIOs; numbered N .. N+(ngpio - 1)\n\nGPIOs claimed by kernel code may be exported by its owner using a new\ngpio_export() call, which should be most useful for driver debugging.\nSuch exports may optionally be done without a \"direction\" attribute.\n\nUserspace may ask to take over a GPIO by writing to a sysfs control file,\nhelping to cope with incomplete board support or other \"one-off\"\nrequirements that don\u0027t merit full kernel support:\n\n  echo 23 \u003e /sys/class/gpio/export\n\t... will gpio_request(23, \"sysfs\") and gpio_export(23);\n\tuse /sys/class/gpio/gpio-23/direction to (re)configure it,\n\twhen that GPIO can be used as both input and output.\n  echo 23 \u003e /sys/class/gpio/unexport\n\t... will gpio_free(23), when it was exported as above\n\nThe extra D-space footprint is a few hundred bytes, except for the sysfs\nresources associated with each exported GPIO.  The additional I-space\nfootprint is about two thirds of the current size of gpiolib (!).  Since\nno /dev node creation is involved, no \"udev\" support is needed.\n\nRelated changes:\n\n  * This adds a device pointer to \"struct gpio_chip\".  When GPIO\n    providers initialize that, sysfs gpio class devices become children of\n    that device instead of being \"virtual\" devices.\n\n  * The (few) gpio_chip providers which have such a device node have\n    been updated.\n\n  * Some gpio_chip drivers also needed to update their module \"owner\"\n    field ...  for which missing kerneldoc was added.\n\n  * Some gpio_chips don\u0027t support input GPIOs.  Those GPIOs are now\n    flagged appropriately when the chip is registered.\n\nBased on previous patches, and discussion both on and off LKML.\n\nA Documentation/ABI/testing/sysfs-gpio update is ready to submit once this\nmerges to mainline.\n\n[akpm@linux-foundation.org: a few maintenance build fixes]\nSigned-off-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nCc: Guennadi Liakhovetski \u003cg.liakhovetski@pengutronix.de\u003e\nCc: Greg KH \u003cgreg@kroah.com\u003e\nCc: Kay Sievers \u003ckay.sievers@vrfy.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

The\nlack of such a flexible kernel API has been a big factor in the proliferation\nof board-specific drivers for these chips...  stuff that rarely makes it\nupstream since it\u0027s so ugly.  This driver will let such boards use standard\ncalls.\n\nSince it\u0027s a new-style driver, these devices must be configured as part of\nboard-specific init.  That eliminates the need for error-prone manual\nconfiguration of module parameters, and makes compatibility with legacy\ndrivers (pcf8574.c, pc8575.c) for these chips easier (there\u0027s a clear\neither/or disjunction).\n\nSigned-off-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nAcked-by: Jean Delvare \u003ckhali@linux-fr.org\u003e\nCc: Eric Miao \u003ceric.miao@marvell.com\u003e\nCc: Sam Ravnborg \u003csam@ravnborg.org\u003e\nCc: Haavard Skinnemoen \u003chskinnemoen@atmel.com\u003e\nCc: Philipp Zabel \u003cphilipp.zabel@gmail.com\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nCc: Ben Gardner \u003cbgardner@wabtec.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
