6 the right in-kernel and userspace APIs/ABIs for the job, and that these
10 - leds-gpio: drivers/leds/leds-gpio.c will handle LEDs connected to GPIO
13 - ledtrig-gpio: drivers/leds/trigger/ledtrig-gpio.c will provide a LED trigger,
14 i.e. a LED will turn on/off in response to a GPIO line going high or low
15 (and that LED may in turn use the leds-gpio as per above).
17 - gpio-keys: drivers/input/keyboard/gpio_keys.c is used when your GPIO line
20 - gpio-keys-polled: drivers/input/keyboard/gpio_keys_polled.c is used when your
24 - gpio_mouse: drivers/input/mouse/gpio_mouse.c is used to provide a mouse with
29 - gpio-beeper: drivers/input/misc/gpio-beeper.c is used to provide a beep from
32 - extcon-gpio: drivers/extcon/extcon-gpio.c is used when you need to read an
36 - restart-gpio: drivers/power/reset/gpio-restart.c is used to restart/reboot
37 the system by pulling a GPIO line and will register a restart handler so
38 userspace can issue the right system call to restart the system.
40 - poweroff-gpio: drivers/power/reset/gpio-poweroff.c is used to power the
41 system down by pulling a GPIO line and will register a pm_power_off()
42 callback so that userspace can issue the right system call to power down the
43 system.
45 - gpio-gate-clock: drivers/clk/clk-gpio.c is used to control a gated clock
46 (off/on) that uses a GPIO, and integrated with the clock subsystem.
48 - i2c-gpio: drivers/i2c/busses/i2c-gpio.c is used to drive an I2C bus
50 appear as any other I2C bus to the system and makes it possible to connect
51 drivers for the I2C devices on the bus like any other I2C bus driver.
53 - spi_gpio: drivers/spi/spi-gpio.c is used to drive an SPI bus (variable number
54 of wires, at least SCK and optionally MISO, MOSI and chip select lines) using
55 GPIO hammering (bitbang). It will appear as any other SPI bus on the system
56 and makes it possible to connect drivers for SPI devices on the bus like
60 - w1-gpio: drivers/w1/masters/w1-gpio.c is used to drive a one-wire bus using
61 a GPIO line, integrating with the W1 subsystem and handling devices on
64 - gpio-fan: drivers/hwmon/gpio-fan.c is used to control a fan for cooling the
65 system, connected to a GPIO line (and optionally a GPIO alarm line),
66 presenting all the right in-kernel and sysfs interfaces to make your system
69 - gpio-regulator: drivers/regulator/gpio-regulator.c is used to control a
73 - gpio-wdt: drivers/watchdog/gpio_wdt.c is used to provide a watchdog timer
75 it from 1-to-0-to-1. If that hardware does not receive its "ping"
76 periodically, it will reset the system.
78 - gpio-nand: drivers/mtd/nand/raw/gpio.c is used to connect a NAND flash chip
80 NAND flash MTD subsystem and provides chip access and partition parsing like
83 - ps2-gpio: drivers/input/serio/ps2-gpio.c is used to drive a PS/2 (IBM) serio
85 any other serio bus to the system and makes it possible to connect drivers
88 - cec-gpio: drivers/media/platform/cec-gpio/ is used to interact with a CEC
90 with devices on the HDMI bus.
92 - gpio-charger: drivers/power/supply/gpio-charger.c is used if you need to do
99 - gpio-mux: drivers/mux/gpio.c is used for controlling a multiplexer using
101 different GPIO lines. Often the GPIOs are on a SoC and the devices are
102 some SoC-external entities, such as different components on a PCB that
108 MTD NOR flash has add-ons for extra GPIO lines too, though the address bus is
114 speed up your embedded hacking in particular by providing ready-made components.
