Hi,
I=E2=80=99m running current as of last week on a raspberry pi B.
i don=E2=80=99t know if this only related to arm, but this is what I =
have in my rpi-b.dts:
=E2=80=A6.
spi0 {
rfid0 {
compatible =3D "rfid,mfrc5";
spi-chipselect =3D <0>;
reset {
compatible =3D "pcd-reset";
gpios =3D <&gpio 6 2>;
};
lock {
compatible =3D "lock-1";
gpios =3D <&gpio 13 2>;
};
sense {
compatible =3D "sense-1";
gpios =3D <&gpio 19 1>;
};=20
};
=E2=80=A6
and a call to
uint32_t data[3];
=09
OF_getprop(node, =E2=80=9Cgpios=E2=80=9D, data, sizeof(data)); =
// node is =E2=80=98pcd-reset'
returns:
data[0]: 0x03000000
data[1]: 0x06000000
data[2]: 0x02000000
which looks to me that it=E2=80=99s in the wrong endian?
cheers,
danny
