Message-ID: <CACUGKYN4uaT0xn4fMCqVNXeKYSf_WP+GkpkAb6vagQeGFdJUmw@mail.gmail.com> (raw)
Hi All,
I was trying to enable the PFUZE100 regulator driver
(pfuze100-regulator) on linux 3.13.0. The PMIC is connected to the
i2c2 bus.
&i2c2 {
.....
pmic: pfuze100 at 08 {
compatible = "fsl,pfuze100";
reg = <0x08>;
regulators {
......
};
};
}
After loading the driver, I was getting an error:
pfuze100-regulator 0-0008: unrecognized pfuze chip ID!
Then, I printed the return value of i2c_transfer function and got -5.
Is there anything that I forgot?. I tried to use the i2cget in
userspace and I was able to communicate it to the device.
Regards,
john
