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. | |

36 | Say yes here to support the Atmel PIO4 driver. | |
37 | The PIO4 is new version of Atmel PIO controller, which manages | |
38 | up to 128 fully programmable input/output lines. Each I/O line | |
39 | may be dedicated as a general purpose I/O or be assigned to | |
40 | a function of an embedded peripheral. | |

45 | help | |
46 | This driver supports Broadwell U devices which have an expanded | |
47 | GPIO feature set. The difference is large enough to merit a separate | |
48 | driver from the common Intel ICH6 driver. It supports a total of | |
49 | 95 GPIOs which can be configured from the device tree. | |

98 | config SANDBOX_GPIO |
99 | bool "Enable sandbox GPIO driver" | |
100 | depends on SANDBOX && DM && DM_GPIO | |
101 | help | |
102 | This driver supports some simulated GPIOs which can be adjusted | |
103 | using 'back door' functions like sandbox_gpio_set_value(). Then the | |
104 | GPIOs can be inspected through the normal get_get_value() | |
105 | interface. The purpose of this is to allow GPIOs to be used as | |
106 | normal in sandbox, perhaps with test code actually driving the | |
107 | behaviour of those GPIOs. | |

112 | default 128 | |
113 | help | |
114 | The sandbox driver can support any number of GPIOs. Generally these | |
115 | are specified using the device tree. But you can also have a number | |
116 | of 'anonymous' GPIOs that do not belong to any device or bank. | |
117 | Select a suitable value depending on your needs. | |

199 | config MPC85XX_GPIO | |
200 | bool "Freescale MPC85XX GPIO driver" | |
201 | depends on DM_GPIO | |
202 | help | |
203 | This driver supports the built-in GPIO controller of MPC85XX CPUs. | |
204 | Each GPIO bank is identified by its own entry in the device tree, | |
205 | i.e. | |
206 | ||
207 | gpio-controller@fc00 { | |
208 | #gpio-cells = <2>; | |
209 | compatible = "fsl,pq3-gpio"; | |
210 | reg = <0xfc00 0x100> | |
211 | } | |
212 | ||
213 | By default, each bank is assumed to have 32 GPIOs, but the ngpios | |
214 | setting is honored, so the number of GPIOs for each bank is | |
215 | configurable to match the actual GPIO count of the SoC (e.g. the | |
216 | 32/32/23 banks of the P1022 SoC). | |
217 | ||
51781783 | 218 | Aside from the standard functions of input/output mode, and output |
219 | value setting, the open-drain feature, which can configure individual | |
220 | GPIOs to work as open-drain outputs, is supported. | |
07d31f8f | 221 | |
222 | The driver has been tested on MPC85XX, but it is likely that other | |
223 | PowerQUICC III devices will work as well. | |
