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.
16
17config GPIO_HOG
18	bool "Enable GPIO hog support"
19	depends on DM_GPIO
20	default n
21	help
22	  Enable gpio hog support

24	  is a mechanism providing automatic GPIO request and config-
25	  uration as part of the gpio-controller's driver probe function.
26
27config ALTERA_PIO
28	bool "Altera PIO driver"
29	depends on DM_GPIO

50	default n
51	help
52	  Say yes here to select AT91 PIO GPIO driver. AT91 PIO
53	  controller manages up to 32 fully programmable input/output
54	  lines. Each I/O line may be dedicated as a general-purpose
55	  I/O or be assigned to a function of an embedded peripheral.
56	  The assignment to a function of an embedded peripheral is
57	  the responsibility of AT91 Pinctrl driver. This driver is
58	  responsible for the general-purpose I/O.
59
60config ATMEL_PIO4
61	bool "ATMEL PIO4 driver"
62	depends on DM_GPIO
63	default n

81config INTEL_BROADWELL_GPIO
82	bool "Intel Broadwell GPIO driver"
83	depends on DM
84	help
85	  This driver supports Broadwell U devices which have an expanded
86	  GPIO feature set. The difference is large enough to merit a separate
87	  driver from the common Intel ICH6 driver. It supports a total of
88	  95 GPIOs which can be configured from the device tree.
89
90config INTEL_ICH6_GPIO
91	bool "Intel ICH6 compatible legacy GPIO driver"

123          the number of available GPIOs with a minimum number of
124          additional pins on the device. The primary purpose of the
125          SIO controller is to connect control signals from SFP
126          modules and to act as an LED controller.
127

155config CMD_PCA953X
156	bool "Enable the pca953x command"
157	help
158	  Deprecated: This should be converted to driver model.
159
160	  This command provides access to a pca953x GPIO device using the
161	  legacy GPIO interface. Several subcommands are provided which mirror
162	  the standard 'gpio' command. It should use that instead.
163
164config PM8916_GPIO
165	bool "Qualcomm PM8916 PMIC GPIO/keypad driver"
166	depends on DM_GPIO && PMIC_PM8916
167	help

194	  for each bank.
195
196config SANDBOX_GPIO
197	bool "Enable sandbox GPIO driver"
198	depends on SANDBOX && DM && DM_GPIO
199	help
200	  This driver supports some simulated GPIOs which can be adjusted
201	  using 'back door' functions like sandbox_gpio_set_value(). Then the
202	  GPIOs can be inspected through the normal get_get_value()
203	  interface. The purpose of this is to allow GPIOs to be used as
204	  normal in sandbox, perhaps with test code actually driving the
205	  behaviour of those GPIOs.
206
207config SANDBOX_GPIO_COUNT
208	int "Number of sandbox GPIOs"
209	depends on SANDBOX_GPIO

212	  The sandbox driver can support any number of GPIOs. Generally these
213	  are specified using the device tree. But you can also have a number
214	  of 'anonymous' GPIOs that do not belong to any device or bank.
215	  Select a suitable value depending on your needs.
216
217config XILINX_GPIO

225	help
226	  DEPRECATED - This needs conversion to driver model
227
228	  This provides a way to looking at the pin state of this device.
229	  This mirrors the 'gpio' command and that should be used in preference
230	  to custom code.
231
232config TEGRA_GPIO
233	bool "Tegra20..210 GPIO driver"
234	depends on DM_GPIO
235	help
236	  Support for the GPIO controller contained in NVIDIA Tegra20 through

345	bool "Freescale MPC8XXX GPIO driver"
346	depends on DM_GPIO
347	help
348	  This driver supports the built-in GPIO controller of MPC8XXX CPUs.
349	  Each GPIO bank is identified by its own entry in the device tree,
350	  i.e.

352	  gpio-controller@fc00 {
353		#gpio-cells = <2>;
354		compatible = "fsl,pq3-gpio";
355		reg = <0xfc00 0x100>
356	  }
357
358	  By default, each bank is assumed to have 32 GPIOs, but the ngpios
359	  setting is honored, so the number of GPIOs for each bank is
360	  configurable to match the actual GPIO count of the SoC (e.g. the
361	  32/32/23 banks of the P1022 SoC).
362
363	  Aside from the standard functions of input/output mode, and output
364	  value setting, the open-drain feature, which can configure individual
365	  GPIOs to work as open-drain outputs, is supported.
