132	  Deprecated: This should be converted to driver model.
133
134	  This command provides access to a pca953x GPIO device using the
135	  legacy GPIO interface. Several subcommands are provided which mirror
136	  the standard 'gpio' command. It should use that instead.
137
138config PM8916_GPIO
139	bool "Qualcomm PM8916 PMIC GPIO/keypad driver"
140	depends on DM_GPIO && PMIC_PM8916

168	  for each bank.
169
170config SANDBOX_GPIO
171	bool "Enable sandbox GPIO driver"
172	depends on SANDBOX && DM && DM_GPIO
173	help
174	  This driver supports some simulated GPIOs which can be adjusted
175	  using 'back door' functions like sandbox_gpio_set_value(). Then the
176	  GPIOs can be inspected through the normal get_get_value()
177	  interface. The purpose of this is to allow GPIOs to be used as
178	  normal in sandbox, perhaps with test code actually driving the
179	  behaviour of those GPIOs.
180

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

199	help
200	  DEPRECATED - This needs conversion to driver model
201
202	  This provides a way to looking at the pin state of this device.
203	  This mirrors the 'gpio' command and that should be used in preference
204	  to custom code.
205
206config TEGRA_GPIO
207	bool "Tegra20..210 GPIO driver"
208	depends on DM_GPIO
209	help
210	  Support for the GPIO controller contained in NVIDIA Tegra20 through

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

295config MPC8XXX_GPIO
296	bool "Freescale MPC8XXX GPIO driver"
297	depends on DM_GPIO
298	help
299	  This driver supports the built-in GPIO controller of MPC8XXX CPUs.
300	  Each GPIO bank is identified by its own entry in the device tree,
301	  i.e.
302
303	  gpio-controller@fc00 {
304		#gpio-cells = <2>;
305		compatible = "fsl,pq3-gpio";
306		reg = <0xfc00 0x100>
307	  }
308
309	  By default, each bank is assumed to have 32 GPIOs, but the ngpios
310	  setting is honored, so the number of GPIOs for each bank is
311	  configurable to match the actual GPIO count of the SoC (e.g. the
312	  32/32/23 banks of the P1022 SoC).
313
314	  Aside from the standard functions of input/output mode, and output
315	  value setting, the open-drain feature, which can configure individual
316	  GPIOs to work as open-drain outputs, is supported.
