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.

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

63	  controller manages up to 32 fully programmable input/output
64	  lines. Each I/O line may be dedicated as a general-purpose
65	  I/O or be assigned to a function of an embedded peripheral.
66	  The assignment to a function of an embedded peripheral is
67	  the responsibility of AT91 Pinctrl driver. This driver is
68	  responsible for the general-purpose I/O.
69
70config ATMEL_PIO4
71	bool "ATMEL PIO4 driver"
72	depends on DM_GPIO
73	default n

92	bool "Intel Broadwell GPIO driver"
93	depends on DM
94	help
95	  This driver supports Broadwell U devices which have an expanded
96	  GPIO feature set. The difference is large enough to merit a separate
97	  driver from the common Intel ICH6 driver. It supports a total of
98	  95 GPIOs which can be configured from the device tree.
99

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

165config CMD_PCA953X
166	bool "Enable the pca953x command"
167	help
168	  Deprecated: This should be converted to driver model.
169
170	  This command provides access to a pca953x GPIO device using the
171	  legacy GPIO interface. Several subcommands are provided which mirror
172	  the standard 'gpio' command. It should use that instead.
173
174config PM8916_GPIO

176	depends on DM_GPIO && PMIC_PM8916

204	  for each bank.
205
206config SANDBOX_GPIO
207	bool "Enable sandbox GPIO driver"
208	depends on SANDBOX && DM && DM_GPIO
209	help
210	  This driver supports some simulated GPIOs which can be adjusted
211	  using 'back door' functions like sandbox_gpio_set_value(). Then the
212	  GPIOs can be inspected through the normal get_get_value()
213	  interface. The purpose of this is to allow GPIOs to be used as
214	  normal in sandbox, perhaps with test code actually driving the
215	  behaviour of those GPIOs.

222	  The sandbox driver can support any number of GPIOs. Generally these
223	  are specified using the device tree. But you can also have a number
224	  of 'anonymous' GPIOs that do not belong to any device or bank.
225	  Select a suitable value depending on your needs.

235	help
236	  DEPRECATED - This needs conversion to driver model
237
238	  This provides a way to looking at the pin state of this device.
239	  This mirrors the 'gpio' command and that should be used in preference
240	  to custom code.
241
242config TEGRA_GPIO
243	bool "Tegra20..210 GPIO driver"
244	depends on DM_GPIO

356	depends on DM_GPIO
357	help
358	  This driver supports the built-in GPIO controller of MPC8XXX CPUs.
359	  Each GPIO bank is identified by its own entry in the device tree,

366	  }
367
368	  By default, each bank is assumed to have 32 GPIOs, but the ngpios
369	  setting is honored, so the number of GPIOs for each bank is
370	  configurable to match the actual GPIO count of the SoC (e.g. the
371	  32/32/23 banks of the P1022 SoC).
372

374	  value setting, the open-drain feature, which can configure individual
375	  GPIOs to work as open-drain outputs, is supported.
