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