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. | |

44 | depends on DM | |
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. | |

62 | help | |
63 | Support GPIO controllers on Qualcomm Snapdragon family of SoCs. | |
64 | This controller have single bank (default name "soc"), every | |
65 | gpio has it's own set of registers. | |
66 | Only simple GPIO operations are supported (get/set, change of | |
67 | direction and checking pin function). | |
68 | Supported devices: | |
69 | - APQ8016 | |
70 | - MSM8916 | |

75 | help | |
76 | Support for GPIO pins and power/reset buttons found on | |
77 | Qualcomm PM8916 PMIC. | |
78 | Default name for GPIO bank is "pm8916". | |
79 | Power and reset buttons are placed in "pm8916_key" bank and | |
80 | have gpio numbers 0 and 1 respectively. | |

85 | help | |
86 | Support GPIO access on Rockchip SoCs. The GPIOs are arranged into | |
87 | a number of banks (different for each SoC type) each with 32 GPIOs. | |
88 | The GPIOs for a device are defined in the device tree with one node | |
89 | for each bank. | |

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

102 | config SANDBOX_GPIO_COUNT | |
103 | int "Number of sandbox GPIOs" | |
104 | depends on SANDBOX_GPIO | |
105 | default 128 | |
106 | help | |
107 | The sandbox driver can support any number of GPIOs. Generally these | |
108 | are specified using the device tree. But you can also have a number | |
109 | of 'anonymous' GPIOs that do not belong to any device or bank. | |
110 | Select a suitable value depending on your needs. | |
