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.

125	bool "Enable the pca953x command"
126	help
127	  Deprecated: This should be converted to driver model.
128
129	  This command provides access to a pca953x GPIO device using the
130	  legacy GPIO interface. Several subcommands are provided which mirror
131	  the standard 'gpio' command. It should use that instead.
132
133config PM8916_GPIO
134	bool "Qualcomm PM8916 PMIC GPIO/keypad driver"
135	depends on DM_GPIO && PMIC_PM8916
136	help

163	  for each bank.
164
165config SANDBOX_GPIO
166	bool "Enable sandbox GPIO driver"
167	depends on SANDBOX && DM && DM_GPIO
168	help
169	  This driver supports some simulated GPIOs which can be adjusted
170	  using 'back door' functions like sandbox_gpio_set_value(). Then the
171	  GPIOs can be inspected through the normal get_get_value()
172	  interface. The purpose of this is to allow GPIOs to be used as
173	  normal in sandbox, perhaps with test code actually driving the
174	  behaviour of those GPIOs.
175

178	depends on SANDBOX_GPIO
179	default 128
180	help
181	  The sandbox driver can support any number of GPIOs. Generally these
182	  are specified using the device tree. But you can also have a number
183	  of 'anonymous' GPIOs that do not belong to any device or bank.
184	  Select a suitable value depending on your needs.

194	help
195	  DEPRECATED - This needs conversion to driver model
196
197	  This provides a way to looking at the pin state of this device.
198	  This mirrors the 'gpio' command and that should be used in preference
199	  to custom code.
200
201config TEGRA_GPIO
202	bool "Tegra20..210 GPIO driver"
203	depends on DM_GPIO
204	help
205	  Support for the GPIO controller contained in NVIDIA Tegra20 through

268	bool "PCA95[357]x, PCA9698, TCA64xx, and MAX7310 I/O ports"
269	depends on DM_GPIO
270	help
271	  Say yes here to provide access to several register-oriented
272	  SMBus I/O expanders, made mostly by NXP or TI.  Compatible
273	  models include:

290config MPC8XXX_GPIO
291	bool "Freescale MPC8XXX GPIO driver"
292	depends on DM_GPIO
293	help
294	  This driver supports the built-in GPIO controller of MPC8XXX CPUs.
295	  Each GPIO bank is identified by its own entry in the device tree,
296	  i.e.
297
298	  gpio-controller@fc00 {
299		#gpio-cells = <2>;
300		compatible = "fsl,pq3-gpio";
301		reg = <0xfc00 0x100>
302	  }
303
304	  By default, each bank is assumed to have 32 GPIOs, but the ngpios
305	  setting is honored, so the number of GPIOs for each bank is
306	  configurable to match the actual GPIO count of the SoC (e.g. the
307	  32/32/23 banks of the P1022 SoC).
308
309	  Aside from the standard functions of input/output mode, and output
310	  value setting, the open-drain feature, which can configure individual
311	  GPIOs to work as open-drain outputs, is supported.
