For consistency, please do the same here:

and here:

Why not go one step further:
u32 mask = BIT(data->desc->resets[idx].bit);
return regmap_update_bits(data->regmap, data->desc->offset, mask, mask);
That seems to be a common pattern in other qcom drivers.
Either way, with the above reset/num_reset changes:

Also,

for the whole series to go through the qcom tree, or let me know if you
want me to pick up patches 2-4 next round.
