Subject: regulator: s2mps11: Question about the code updating ramp_delay setting
Date: Sat, 03 Aug 2013 17:13:08 +0800	[thread overview]
Message-ID: <1375521188.3891.3.camel@phoenix> (raw)

Hi Yadwinder,
The code updating ramp_delay setting looks wrong to me.

Current code:
        return regmap_update_bits(rdev->regmap, ramp_reg,
                                  ramp_val << ramp_shift, 1 << ramp_shift);
I'd expect something like below:
        return regmap_update_bits(rdev->regmap, ramp_reg,
                                  ramp_mask << ramp_shift,
                                  ramp_val << ramp_shift);
I don't have the datasheet so I don't know the correct ramp_mask setting
here. Can you check if this needs fix?

Thanks,
Axel
