Simon Glassd8b771d2015-02-05 21:41:35 -0700[diff] [blame]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.

166 GPIOs can be inspected through the normal get_get_value()

168 normal in sandbox, perhaps with test code actually driving the
169 behaviour of those GPIOs.

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).
