7config DM_GPIO
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.

38	bool "AT91 PIO GPIO driver"
39	depends on DM_GPIO
40	default n
41	help
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.
46	  The assignment to a function of an embedded peripheral is
47	  the responsibility of AT91 Pinctrl driver. This driver is
48	  responsible for the general-purpose I/O.

108          the number of available GPIOs with a minimum number of
109          additional pins on the device. The primary purpose of the
110          SIO controller is to connect control signals from SFP

140config CMD_PCA953X
141	bool "Enable the pca953x command"
142	help
143	  Deprecated: This should be converted to driver model.
144
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.
148
149config PM8916_GPIO

151	depends on DM_GPIO && PMIC_PM8916
152	help

179	  for each bank.
180
181config SANDBOX_GPIO
182	bool "Enable sandbox GPIO driver"
183	depends on SANDBOX && DM && DM_GPIO
184	help
185	  This driver supports some simulated GPIOs which can be adjusted
186	  using 'back door' functions like sandbox_gpio_set_value(). Then the
187	  GPIOs can be inspected through the normal get_get_value()
188	  interface. The purpose of this is to allow GPIOs to be used as
189	  normal in sandbox, perhaps with test code actually driving the
190	  behaviour of those GPIOs.
191
192config SANDBOX_GPIO_COUNT
193	int "Number of sandbox GPIOs"
194	depends on SANDBOX_GPIO
195	default 128
196	help
197	  The sandbox driver can support any number of GPIOs. Generally these
198	  are specified using the device tree. But you can also have a number
199	  of 'anonymous' GPIOs that do not belong to any device or bank.
200	  Select a suitable value depending on your needs.
201
202config XILINX_GPIO

210	help
211	  DEPRECATED - This needs conversion to driver model
212
213	  This provides a way to looking at the pin state of this device.
214	  This mirrors the 'gpio' command and that should be used in preference
215	  to custom code.
216
217config TEGRA_GPIO
218	bool "Tegra20..210 GPIO driver"
219	depends on DM_GPIO

284	bool "PCA95[357]x, PCA9698, TCA64xx, and MAX7310 I/O ports"
285	depends on DM_GPIO
286	help
287	  Say yes here to provide access to several register-oriented

306config MPC8XXX_GPIO
307	bool "Freescale MPC8XXX GPIO driver"
308	depends on DM_GPIO
309	help
310	  This driver supports the built-in GPIO controller of MPC8XXX CPUs.
311	  Each GPIO bank is identified by its own entry in the device tree,
312	  i.e.

314	  gpio-controller@fc00 {
315		#gpio-cells = <2>;
316		compatible = "fsl,pq3-gpio";
317		reg = <0xfc00 0x100>
318	  }
319
320	  By default, each bank is assumed to have 32 GPIOs, but the ngpios
321	  setting is honored, so the number of GPIOs for each bank is
322	  configurable to match the actual GPIO count of the SoC (e.g. the
323	  32/32/23 banks of the P1022 SoC).
324
325	  Aside from the standard functions of input/output mode, and output
326	  value setting, the open-drain feature, which can configure individual
327	  GPIOs to work as open-drain outputs, is supported.
328
