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. | |

164 | This driver supports some simulated GPIOs which can be adjusted | |
165 | using 'back door' functions like sandbox_gpio_set_value(). Then the | |
166 | GPIOs can be inspected through the normal get_get_value() | |
167 | interface. The purpose of this is to allow GPIOs to be used as | |
168 | normal in sandbox, perhaps with test code actually driving the | |

279 | config MPC85XX_GPIO | |
280 | bool "Freescale MPC85XX GPIO driver" | |
281 | depends on DM_GPIO | |
282 | help | |
283 | This driver supports the built-in GPIO controller of MPC85XX CPUs. | |
284 | Each GPIO bank is identified by its own entry in the device tree, | |
285 | i.e. | |
286 | ||
287 | gpio-controller@fc00 { | |
288 | #gpio-cells = <2>; | |
289 | compatible = "fsl,pq3-gpio"; | |
290 | reg = <0xfc00 0x100> | |
291 | } | |
292 | ||
293 | By default, each bank is assumed to have 32 GPIOs, but the ngpios | |
294 | setting is honored, so the number of GPIOs for each bank is | |
295 | configurable to match the actual GPIO count of the SoC (e.g. the | |
296 | 32/32/23 banks of the P1022 SoC). | |
297 | ||
51781783 | 298 | Aside from the standard functions of input/output mode, and output |
299 | value setting, the open-drain feature, which can configure individual | |
300 | GPIOs to work as open-drain outputs, is supported. | |
07d31f8f | 301 | |
302 | The driver has been tested on MPC85XX, but it is likely that other | |
303 | PowerQUICC III devices will work as well. | |
