4 1) gpios property5 -----------------7 GPIO properties should be named "[<name>-]gpios", with <name> being the purpose8 of this GPIO for the device. While a non-existent <name> is considered valid9 for compatibility reasons (resolving to the "gpios" property), it is not allowed10 for new bindings. Also, GPIO properties named "[<name>-]gpio" are valid and old15 cases should they contain more than one. If your device uses several GPIOs with17 meaningful name. The only case where an array of GPIOs is accepted is when18 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[all …]
13 Internal Representation of GPIOs26 between 0 and n-1, n being the number of GPIOs managed by the chip.29 example if a system uses a memory-mapped set of I/O-registers where 32 GPIO30 lines are handled by one bit per line in a 32-bit register, it makes sense to44 So for example one platform could use global numbers 32-159 for GPIOs, with a45 controller defining 128 GPIOs at a "base" of 32 ; while another platform uses46 global numbers 0..63 with one set of GPIO controllers, 64-79 with another type47 of GPIO controller, and on one particular board 80-95 with an FPGA.
