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
11 lines, giving you the LED sysfs interface
13 - ledtrig-gpio: drivers/leds/trigger/ledtrig-gpio.c will provide a LED trigger,
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
26 mouse cable and connect the wires to GPIO lines or solder a mouse connector
27 to the lines for a more permanent solution of this type.
29 - gpio-beeper: drivers/input/misc/gpio-beeper.c is used to provide a beep from
31 off/on, for an actual PWM waveform, see pwm-gpio below.)
33 - pwm-gpio: drivers/pwm/pwm-gpio.c is used to toggle a GPIO with a high
37 - extcon-gpio: drivers/extcon/extcon-gpio.c is used when you need to read an
41 - restart-gpio: drivers/power/reset/gpio-restart.c is used to restart/reboot
45 - poweroff-gpio: drivers/power/reset/gpio-poweroff.c is used to power the
50 - gpio-gate-clock: drivers/clk/clk-gpio.c is used to control a gated clock
53 - i2c-gpio: drivers/i2c/busses/i2c-gpio.c is used to drive an I2C bus
54 (two wires, SDA and SCL lines) by hammering (bitbang) two GPIO lines. It will
58 - spi_gpio: drivers/spi/spi-gpio.c is used to drive an SPI bus (variable number
59 of wires, at least SCK and optionally MISO, MOSI and chip select lines) using
62 any other SPI bus driver. For example any MMC/SD card can then be connected
63 to this SPI by using the mmc_spi host from the MMC/SD card subsystem.
65 - w1-gpio: drivers/w1/masters/w1-gpio.c is used to drive a one-wire bus using
69 - gpio-fan: drivers/hwmon/gpio-fan.c is used to control a fan for cooling the
71 presenting all the right in-kernel and sysfs interfaces to make your system
74 - gpio-regulator: drivers/regulator/gpio-regulator.c is used to control a
78 - gpio-wdt: drivers/watchdog/gpio_wdt.c is used to provide a watchdog timer
80 it from 1-to-0-to-1. If that hardware does not receive its "ping"
83 - gpio-nand: drivers/mtd/nand/raw/gpio.c is used to connect a NAND flash chip
84 to a set of simple GPIO lines: RDY, NCE, ALE, CLE, NWP. It interacts with the
88 - ps2-gpio: drivers/input/serio/ps2-gpio.c is used to drive a PS/2 (IBM) serio
89 bus, data and clock line, by bit banging two GPIO lines. It will appear as
93 - cec-gpio: drivers/media/platform/cec-gpio/ is used to interact with a CEC
97 - gpio-charger: drivers/power/supply/gpio-charger.c is used if you need to do
100 nothing but GPIO lines, this driver provides that and also a clearly defined
104 - gpio-mux: drivers/mux/gpio.c is used for controlling a multiplexer using
105 n GPIO lines such that you can mux in 2^n different devices by activating
106 different GPIO lines. Often the GPIOs are on a SoC and the devices are
107 some SoC-external entities, such as different components on a PCB that
110 Apart from this there are special GPIO drivers in subsystems like MMC/SD to
111 read card detect and write protect GPIO lines, and in the TTY serial subsystem
112 to emulate MCTRL (modem control) signals CTS/RTS by using two GPIO lines. The
113 MTD NOR flash has add-ons for extra GPIO lines too, though the address bus is
119 speed up your embedded hacking in particular by providing ready-made components.
