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.

17config ALTERA_PIO
18	bool "Altera PIO driver"
19	depends on DM_GPIO
20	help
21	  Select this to enable PIO for Altera devices. Please find
22	  details on the "Embedded Peripherals IP User Guide" of Altera.

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.

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

62	bool "Intel Broadwell GPIO driver"
63	depends on DM
64	help
65	  This driver supports Broadwell U devices which have an expanded
66	  GPIO feature set. The difference is large enough to merit a separate
67	  driver from the common Intel ICH6 driver. It supports a total of
68	  95 GPIOs which can be configured from the device tree.

106	  direction and checking pin function).
107	  Supported devices:
108	  - APQ8016
109	  - MSM8916
110
111config OMAP_GPIO

118
119config CMD_PCA953X
120	bool "Enable the pca953x command"
121	help
122	  Deprecated: This should be converted to driver model.
123
124	  This command provides access to a pca953x GPIO device using the
125	  legacy GPIO interface. Several subcommands are provided which mirror
126	  the standard 'gpio' command. It should use that instead.
127
128config PM8916_GPIO
129	bool "Qualcomm PM8916 PMIC GPIO/keypad driver"
130	depends on DM_GPIO && PMIC_PM8916
131	help
132	  Support for GPIO pins and power/reset buttons found on
133	  Qualcomm PM8916 PMIC.

135	  Power and reset buttons are placed in "pm8916_key" bank and
136          have gpio numbers 0 and 1 respectively.

154	help
155	  Support GPIO access on Rockchip SoCs. The GPIOs are arranged into
156	  a number of banks (different for each SoC type) each with 32 GPIOs.
157	  The GPIOs for a device are defined in the device tree with one node
158	  for each bank.
159
160config SANDBOX_GPIO
161	bool "Enable sandbox GPIO driver"
162	depends on SANDBOX && DM && DM_GPIO
163	help
164	  This driver supports some simulated GPIOs which can be adjusted
165	  using 'back door' functions like sandbox_gpio_set_value(). Then the
166	  GPIOs can be inspected through the normal get_get_value()
167	  interface. The purpose of this is to allow GPIOs to be used as
168	  normal in sandbox, perhaps with test code actually driving the
169	  behaviour of those GPIOs.
170
171config SANDBOX_GPIO_COUNT
172	int "Number of sandbox GPIOs"
173	depends on SANDBOX_GPIO
174	default 128
175	help
176	  The sandbox driver can support any number of GPIOs. Generally these
177	  are specified using the device tree. But you can also have a number
178	  of 'anonymous' GPIOs that do not belong to any device or bank.
179	  Select a suitable value depending on your needs.
180
181config CMD_TCA642X
182	bool "tca642x - Command to access tca642x state"
183	help
184	  DEPRECATED - This needs conversion to driver model
185
186	  This provides a way to looking at the pin state of this device.
187	  This mirrors the 'gpio' command and that should be used in preference
188	  to custom code.
189
190config TEGRA_GPIO
191	bool "Tegra20..210 GPIO driver"
192	depends on DM_GPIO
193	help
194	  Support for the GPIO controller contained in NVIDIA Tegra20 through
195	  Tegra210.

199	depends on DM_GPIO
200	help
201	  Support for the GPIO controller contained in NVIDIA Tegra186. This
202	  covers both the "main" and "AON" controller instances, even though
203	  they have slightly different register layout.

253	  shift registers, such as 74lv165, 74hc595.
254	  This driver can be used to provide access to more gpio outputs.
255
256config DM_PCA953X
257	bool "PCA95[357]x, PCA9698, TCA64xx, and MAX7310 I/O ports"
258	depends on DM_GPIO
259	help
260	  Say yes here to provide access to several register-oriented
261	  SMBus I/O expanders, made mostly by NXP or TI.  Compatible
262	  models include:
263
264	  4 bits:	pca9536, pca9537
265
266	  8 bits:	max7310, max7315, pca6107, pca9534, pca9538, pca9554,

279config MPC8XXX_GPIO
280	bool "Freescale MPC8XXX GPIO driver"
281	depends on DM_GPIO
282	help
283	  This driver supports the built-in GPIO controller of MPC8XXX CPUs.
284	  Each GPIO bank is identified by its own entry in the device tree,
285	  i.e.
286
287	  gpio-controller@fc00 {
288		#gpio-cells = <2>;
289		compatible = "fsl,pq3-gpio";
290		reg = <0xfc00 0x100>
291	  }
292
293	  By default, each bank is assumed to have 32 GPIOs, but the ngpios
294	  setting is honored, so the number of GPIOs for each bank is
295	  configurable to match the actual GPIO count of the SoC (e.g. the
296	  32/32/23 banks of the P1022 SoC).
297
298	  Aside from the standard functions of input/output mode, and output
299	  value setting, the open-drain feature, which can configure individual
300	  GPIOs to work as open-drain outputs, is supported.
