7 config 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.

17 config 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.

24 config BCM6345_GPIO
25 	bool "BCM6345 GPIO driver"
26 	depends on DM_GPIO && ARCH_BMIPS
27 	help

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.

50 config ATMEL_PIO4
51 	bool "ATMEL PIO4 driver"
52 	depends on DM_GPIO

61 config INTEL_BROADWELL_GPIO
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.
69

109 	help
110 	  Support for GPIO pins and power/reset buttons found on
111 	  Qualcomm PM8916 PMIC.

124 	bool "Rockchip GPIO driver"
125 	depends on DM_GPIO
126 	help
127 	  Support GPIO access on Rockchip SoCs. The GPIOs are arranged into
128 	  a number of banks (different for each SoC type) each with 32 GPIOs.
129 	  The GPIOs for a device are defined in the device tree with one node
130 	  for each bank.
131 
132 config SANDBOX_GPIO
133 	bool "Enable sandbox GPIO driver"
134 	depends on SANDBOX && DM && DM_GPIO
135 	help
136 	  This driver supports some simulated GPIOs which can be adjusted
137 	  using 'back door' functions like sandbox_gpio_set_value(). Then the
138 	  GPIOs can be inspected through the normal get_get_value()
139 	  interface. The purpose of this is to allow GPIOs to be used as
140 	  normal in sandbox, perhaps with test code actually driving the
141 	  behaviour of those GPIOs.
142 
143 config SANDBOX_GPIO_COUNT
144 	int "Number of sandbox GPIOs"
145 	depends on SANDBOX_GPIO
146 	default 128
147 	help
148 	  The sandbox driver can support any number of GPIOs. Generally these
149 	  are specified using the device tree. But you can also have a number
150 	  of 'anonymous' GPIOs that do not belong to any device or bank.
151 	  Select a suitable value depending on your needs.

162 	depends on DM_GPIO
163 	help
164 	  Support for the GPIO controller contained in NVIDIA Tegra186. This
165 	  covers both the "main" and "AON" controller instances, even though
166 	  they have slightly different register layout.

221 	depends on DM_GPIO
222 	help
223 	  Say yes here to provide access to several register-oriented
224 	  SMBus I/O expanders, made mostly by NXP or TI.  Compatible
225 	  models include:
226 
227 	  4 bits:	pca9536, pca9537
228 
229 	  8 bits:	max7310, max7315, pca6107, pca9534, pca9538, pca9554,
230 			pca9556, pca9557, pca9574, tca6408, xra1202
231

240 	  supported
241 
242 config MPC85XX_GPIO
243 	bool "Freescale MPC85XX GPIO driver"
244 	depends on DM_GPIO
245 	help
246 	  This driver supports the built-in GPIO controller of MPC85XX CPUs.
247 	  Each GPIO bank is identified by its own entry in the device tree,
248 	  i.e.
249 
250 	  gpio-controller@fc00 {
251 		#gpio-cells = <2>;
252 		compatible = "fsl,pq3-gpio";
253 		reg = <0xfc00 0x100>
254 	  }
255 
256 	  By default, each bank is assumed to have 32 GPIOs, but the ngpios
257 	  setting is honored, so the number of GPIOs for each bank is
258 	  configurable to match the actual GPIO count of the SoC (e.g. the
259 	  32/32/23 banks of the P1022 SoC).
260 
261 	  Aside from the standard functions of input/output mode, and output
262 	  value setting, the open-drain feature, which can configure individual
263 	  GPIOs to work as open-drain outputs, is supported.
264 
265 	  The driver has been tested on MPC85XX, but it is likely that other
266 	  PowerQUICC III devices will work as well.
