173 a number of banks (different for each SoC type) each with 32 GPIOs.
174 The GPIOs for a device are defined in the device tree with one node
178 bool "Enable sandbox GPIO driver"
179 depends on SANDBOX && DM && DM_GPIO
181 This driver supports some simulated GPIOs which can be adjusted
182 using 'back door' functions like sandbox_gpio_set_value(). Then the
183 GPIOs can be inspected through the normal get_get_value()
184 interface. The purpose of this is to allow GPIOs to be used as
185 normal in sandbox, perhaps with test code actually driving the
186 behaviour of those GPIOs.
188 config SANDBOX_GPIO_COUNT
189 int "Number of sandbox GPIOs"
190 depends on SANDBOX_GPIO
193 The sandbox driver can support any number of GPIOs. Generally these
194 are specified using the device tree. But you can also have a number
195 of 'anonymous' GPIOs that do not belong to any device or bank.
196 Select a suitable value depending on your needs.

221 bool "Tegra186 GPIO driver"
224 Support for the GPIO controller contained in NVIDIA Tegra186. This

303 bool "Freescale MPC8XXX GPIO driver"
306 This driver supports the built-in GPIO controller of MPC8XXX CPUs.
307 Each GPIO bank is identified by its own entry in the device tree,
310 gpio-controller@fc00 {
312 compatible = "fsl,pq3-gpio";
316 By default, each bank is assumed to have 32 GPIOs, but the ngpios
317 setting is honored, so the number of GPIOs for each bank is
318 configurable to match the actual GPIO count of the SoC (e.g. the
319 32/32/23 banks of the P1022 SoC).
321 Aside from the standard functions of input/output mode, and output
322 value setting, the open-drain feature, which can configure individual
323 GPIOs to work as open-drain outputs, is supported.
326 bool "MediaTek MT7621 GPIO driver"
327 depends on DM_GPIO && ARCH_MT7620
330 Say yes here to support MediaTek MT7621 compatible GPIOs.
