8	bool "Enable Driver Model for GPIO drivers"
9	depends on DM
10	help
11	  Enable driver model for GPIO access. The standard GPIO
12	  interface (gpio_get_value(), etc.) is then implemented by
13	  the GPIO uclass. Drivers provide methods to query the
14	  particular GPIOs that they provide. The uclass interface
15	  is defined in include/asm-generic/gpio.h.

42	  Say yes here to select AT91 PIO GPIO driver. AT91 PIO
43	  controller manages up to 32 fully programmable input/output
44	  lines. Each I/O line may be dedicated as a general-purpose
45	  I/O or be assigned to a function of an embedded peripheral.

137	bool "Enable the pca953x command"
138	help
139	  Deprecated: This should be converted to driver model.
140
141	  This command provides access to a pca953x GPIO device using the
142	  legacy GPIO interface. Several subcommands are provided which mirror
143	  the standard 'gpio' command. It should use that instead.

178	bool "Enable sandbox GPIO driver"
179	depends on SANDBOX && DM && DM_GPIO
180	help
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.
187
188config SANDBOX_GPIO_COUNT
189	int "Number of sandbox GPIOs"
190	depends on SANDBOX_GPIO
191	default 128
192	help
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.

207	  DEPRECATED - This needs conversion to driver model
208
209	  This provides a way to looking at the pin state of this device.
210	  This mirrors the 'gpio' command and that should be used in preference
211	  to custom code.

281	depends on DM_GPIO
282	help
283	  Say yes here to provide access to several register-oriented

302config MPC8XXX_GPIO
303	bool "Freescale MPC8XXX GPIO driver"
304	depends on DM_GPIO
305	help
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,
308	  i.e.

310	  gpio-controller@fc00 {
311		#gpio-cells = <2>;
312		compatible = "fsl,pq3-gpio";
313		reg = <0xfc00 0x100>
314	  }
315
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).
320
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.
324
325config MT7621_GPIO
