57 for the same functionality in board code.
59 config SPL_DM_GPIO_LOOKUP_LABEL
60 bool "Enable searching for gpio labelnames"
61 depends on DM_GPIO && SPL_DM && SPL_GPIO_SUPPORT

266 using 'back door' functions like sandbox_gpio_set_value(). Then the
267 GPIOs can be inspected through the normal get_get_value()
268 interface. The purpose of this is to allow GPIOs to be used as
269 normal in sandbox, perhaps with test code actually driving the
270 behaviour of those GPIOs.
272 config SANDBOX_GPIO_COUNT
273 int "Number of sandbox GPIOs"

423 bool "Freescale MPC8XXX GPIO driver"
426 This driver supports the built-in GPIO controller of MPC8XXX CPUs.
427 Each GPIO bank is identified by its own entry in the device tree,
430 gpio-controller@fc00 {
432 compatible = "fsl,pq3-gpio";
436 By default, each bank is assumed to have 32 GPIOs, but the ngpios
437 setting is honored, so the number of GPIOs for each bank is
438 configurable to match the actual GPIO count of the SoC (e.g. the
439 32/32/23 banks of the P1022 SoC).
441 Aside from the standard functions of input/output mode, and output
442 value setting, the open-drain feature, which can configure individual
443 GPIOs to work as open-drain outputs, is supported.
