7 Nodes that makes use of GPIOs should specify them using one or more
8 properties, each containing a 'gpio-list':
10 gpio-list ::= <single-gpio> [gpio-list]
11 single-gpio ::= <gpio-phandle> <gpio-specifier>
12 gpio-phandle : phandle to gpio controller node
13 gpio-specifier : Array of #gpio-cells specifying specific gpio
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

5 -----------------
7 GPIO properties should be named "[<name>-]gpios", with <name> being the purpose
8 of this GPIO for the device. While a non-existent <name> is considered valid
9 for compatibility reasons (resolving to the "gpios" property), it is not allowed
10 for new bindings. Also, GPIO properties named "[<name>-]gpio" are valid and old
15 cases should they contain more than one. If your device uses several GPIOs with
17 meaningful name. The only case where an array of GPIOs is accepted is when
18 several GPIOs serve the same function (e.g. a parallel data line).
20 The exact purpose of each gpios property must be documented in the device tree
