145 This command provides access to a pca953x GPIO device using the
146 legacy GPIO interface. Several subcommands are provided which mirror
147 the standard 'gpio' command. It should use that instead.

192 using 'back door' functions like sandbox_gpio_set_value(). Then the
193 GPIOs can be inspected through the normal get_get_value()
194 interface. The purpose of this is to allow GPIOs to be used as
195 normal in sandbox, perhaps with test code actually driving the
196 behaviour of those GPIOs.
198 config SANDBOX_GPIO_COUNT
199 int "Number of sandbox GPIOs"
200 depends on SANDBOX_GPIO
203 The sandbox driver can support any number of GPIOs. Generally these
204 are specified using the device tree. But you can also have a number
205 of 'anonymous' GPIOs that do not belong to any device or bank.

336 bool "Freescale MPC8XXX GPIO driver"
339 This driver supports the built-in GPIO controller of MPC8XXX CPUs.
340 Each GPIO bank is identified by its own entry in the device tree,
343 gpio-controller@fc00 {
345 compatible = "fsl,pq3-gpio";
349 By default, each bank is assumed to have 32 GPIOs, but the ngpios
350 setting is honored, so the number of GPIOs for each bank is
351 configurable to match the actual GPIO count of the SoC (e.g. the
352 32/32/23 banks of the P1022 SoC).
354 Aside from the standard functions of input/output mode, and output
355 value setting, the open-drain feature, which can configure individual
356 GPIOs to work as open-drain outputs, is supported.
359 bool "MediaTek MT7621 GPIO driver"
