|
Enable support for GPIOs (General-purpose Input/Output) in U-Boot.
|
|
GPIOs allow U-Boot to read the state of an input line (high or
|
|
low) and set the state of an output line. This can be used to
|
|
drive LEDs, control power to various system parts and read user
|
|
input. GPIOs can be useful to enable a 'sign-of-life' LED,
|
|
for example. Enable this option to build the drivers in
|
|
drivers/gpio as part of an U-Boot build.

config MPC8XXX_GPIO
|
|
bool "Freescale MPC8XXX GPIO driver"
|
|
depends on DM_GPIO
|
|
help
|
|
This driver supports the built-in GPIO controller of MPC8XXX 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.
