Hi,
devm_gpiod_get method takes 3 params after kernel 3.16 .
struct gpio_desc *gpiod;
gpiod = devm_gpiod_get(dev, "data-pin",GPIOD_OUT_HIGH)
where data-pin defintion in the device tree is :
data-pin = <&gpio2 51 GPIO_ACTIVE_HIGH>;
But this on inserting ht module givees "failed to parse DT (-2)
GPIOD_OUT_HIGH is one of the gpiod flags :
enum gpiod_flags {
GPIOD_ASIS = 0,
GPIOD_IN = GPIOD_FLAGS_BIT_DIR_SET,
GPIOD_OUT_LOW = GPIOD_FLAGS_BIT_DIR_SET |
GPIOD_FLAGS_BIT_DIR_OUT,
GPIOD_OUT_HIGH = GPIOD_FLAGS_BIT_DIR_SET | GPIOD_FLAGS_BIT_DIR_OUT |
GPIOD_FLAGS_BIT_DIR_VAL,
};
what is wrong here?I just want to extract the gpio number for the dt parser.
Thanks and Rgds,
Rp
