1 Specifying GPIO information for devices
16 GPIO properties should be named "[<name>-]gpios", with <name> being the purpose
17 of this GPIO for the device. While a non-existent <name> is considered valid
21 GPIO properties can contain one or more GPIO phandles, but only in exceptional
30 The following example could be used to describe GPIO pins used as device enable
66 GPIO pin number, and GPIO flags as accepted by the "qe_pio_e" gpio-controller.

71 A gpio-specifier should contain a flag indicating the GPIO polarity; active-

115 Every GPIO controller node must contain both an empty "gpio-controller"
119 Example of two SOC GPIO banks defined as gpio-controller nodes:
138 Some or all of the GPIOs provided by a GPIO controller may be routed to pins
140 GPIO and other functions.
