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.

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.
49

51	bool "ATMEL PIO4 driver"
52	depends on DM_GPIO
53	default n

72	bool "Intel Broadwell GPIO driver"
73	depends on DM

78	  95 GPIOs which can be configured from the device tree.
79
80config INTEL_ICH6_GPIO
81	bool "Intel ICH6 compatible legacy GPIO driver"

113          the number of available GPIOs with a minimum number of
114          additional pins on the device. The primary purpose of the
115          SIO controller is to connect control signals from SFP
116          modules and to act as an LED controller.
117
118config MSM_GPIO

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

184	  for each bank.
185
186config SANDBOX_GPIO
187	bool "Enable sandbox GPIO driver"
188	depends on SANDBOX && DM && DM_GPIO
189	help
190	  This driver supports some simulated GPIOs which can be adjusted
191	  using 'back door' functions like sandbox_gpio_set_value(). Then the
192	  GPIOs can be inspected through the normal get_get_value()
193	  interface. The purpose of this is to allow GPIOs to be used as
194	  normal in sandbox, perhaps with test code actually driving the
195	  behaviour of those GPIOs.
196
197config SANDBOX_GPIO_COUNT
198	int "Number of sandbox GPIOs"
199	depends on SANDBOX_GPIO

202	  The sandbox driver can support any number of GPIOs. Generally these
203	  are specified using the device tree. But you can also have a number
204	  of 'anonymous' GPIOs that do not belong to any device or bank.
205	  Select a suitable value depending on your needs.
206
207config XILINX_GPIO

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

335	bool "Freescale MPC8XXX GPIO driver"
336	depends on DM_GPIO
337	help
338	  This driver supports the built-in GPIO controller of MPC8XXX CPUs.
339	  Each GPIO bank is identified by its own entry in the device tree,
340	  i.e.

342	  gpio-controller@fc00 {
343		#gpio-cells = <2>;
344		compatible = "fsl,pq3-gpio";
345		reg = <0xfc00 0x100>
346	  }
347
348	  By default, each bank is assumed to have 32 GPIOs, but the ngpios
349	  setting is honored, so the number of GPIOs for each bank is
350	  configurable to match the actual GPIO count of the SoC (e.g. the
351	  32/32/23 banks of the P1022 SoC).
352
353	  Aside from the standard functions of input/output mode, and output
354	  value setting, the open-drain feature, which can configure individual
355	  GPIOs to work as open-drain outputs, is supported.
