10 - Ramona Nechita <[email protected]>
13 The AD777X family consist of 8-channel, simultaneous sampling analog-to-
14 digital converter (ADC). Eight full Σ-Δ ADCs are on-chip. The
18 outputs into the full-scale ADC input range, maximizing the
19 dynamic range of the signal chain.

Dgpio.txt4 1) gpios property
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
