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.

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.
49
50config ATMEL_PIO4
51	bool "ATMEL PIO4 driver"
52	depends on DM_GPIO
53	default n

68	depends on DM
69	help
70	  This driver supports Broadwell U devices which have an expanded
71	  GPIO feature set. The difference is large enough to merit a separate
72	  driver from the common Intel ICH6 driver. It supports a total of
73	  95 GPIOs which can be configured from the device tree.

111	depends on DM_GPIO && SOC_VCOREIII
112	help
113	  Support for the VCoreIII SoC serial GPIO device. By using a
114          serial interface, the SIO controller significantly extends
115          the number of available GPIOs with a minimum number of
116          additional pins on the device. The primary purpose of the
117          SIO controller is to connect control signals from SFP
118          modules and to act as an LED controller.

148	bool "Enable the pca953x command"
149	help
150	  Deprecated: This should be converted to driver model.
151
152	  This command provides access to a pca953x GPIO device using the
153	  legacy GPIO interface. Several subcommands are provided which mirror
154	  the standard 'gpio' command. It should use that instead.
155
156config PM8916_GPIO
157	bool "Qualcomm PM8916 PMIC GPIO/keypad driver"
158	depends on DM_GPIO && PMIC_PM8916
159	help

185	  The GPIOs for a device are defined in the device tree with one node
186	  for each bank.
187
188config SANDBOX_GPIO
189	bool "Enable sandbox GPIO driver"
190	depends on SANDBOX && DM && DM_GPIO
191	help
192	  This driver supports some simulated GPIOs which can be adjusted
193	  using 'back door' functions like sandbox_gpio_set_value(). Then the
194	  GPIOs can be inspected through the normal get_get_value()
195	  interface. The purpose of this is to allow GPIOs to be used as
196	  normal in sandbox, perhaps with test code actually driving the
197	  behaviour of those GPIOs.
198
199config SANDBOX_GPIO_COUNT
200	int "Number of sandbox GPIOs"
201	depends on SANDBOX_GPIO
202	default 128
203	help
204	  The sandbox driver can support any number of GPIOs. Generally these
205	  are specified using the device tree. But you can also have a number
206	  of 'anonymous' GPIOs that do not belong to any device or bank.
207	  Select a suitable value depending on your needs.
208
209config XILINX_GPIO

217	help
218	  DEPRECATED - This needs conversion to driver model
219
220	  This provides a way to looking at the pin state of this device.
221	  This mirrors the 'gpio' command and that should be used in preference
222	  to custom code.
223
224config TEGRA_GPIO
225	bool "Tegra20..210 GPIO driver"
226	depends on DM_GPIO

291	bool "PCA95[357]x, PCA9698, TCA64xx, and MAX7310 I/O ports"
292	depends on DM_GPIO
293	help
294	  Say yes here to provide access to several register-oriented
295	  SMBus I/O expanders, made mostly by NXP or TI.  Compatible

313config MPC8XXX_GPIO
314	bool "Freescale MPC8XXX GPIO driver"
315	depends on DM_GPIO
316	help
317	  This driver supports the built-in GPIO controller of MPC8XXX CPUs.
318	  Each GPIO bank is identified by its own entry in the device tree,
319	  i.e.

322		#gpio-cells = <2>;
323		compatible = "fsl,pq3-gpio";
324		reg = <0xfc00 0x100>
325	  }
326
327	  By default, each bank is assumed to have 32 GPIOs, but the ngpios
328	  setting is honored, so the number of GPIOs for each bank is
329	  configurable to match the actual GPIO count of the SoC (e.g. the
330	  32/32/23 banks of the P1022 SoC).
331
332	  Aside from the standard functions of input/output mode, and output
333	  value setting, the open-drain feature, which can configure individual
334	  GPIOs to work as open-drain outputs, is supported.
335
336config MT7621_GPIO
337	bool "MediaTek MT7621 GPIO driver"
