Looks like you want regulator_bulk_get() here. Or (better yet though it'd be a potential issue for merge via MFD and the benefits aren't that exciting since you still need to disable) devm_regulator_bulk_get().
I need separate control for the two power source since we can hit different power levels depending on which is powered/not powered: power down: vio, v2v1 is OFF deep sleep: vio is ON, v2v1 is OFF sleep/power on: vio, v2v1 is ON
And we have certain sequence to move between power states.
That's not a problem for using the bulk get - the array is part of the API so you can use regulator_bulk_get() and still look at individual supplies within the array later on when enabling and disabling them.
- ret = regulator_enable(twl6040->vio);
- if (ret != 0) {
dev_err(&client->dev, "Failed to enable VIO: %d\n", ret);
goto power_err;
- }
- ret = regulator_enable(twl6040->v2v1);
- if (ret != 0) {
dev_err(&client->dev, "Failed to enable V2V1: %d\n", ret);
regulator_disable(twl6040->vio);
I disable the vio here, if the v2v1 enable fails.
Oh, that's quite confusing when mixed in with the goto/unwind - it'd be clearer to have the extra lable to jump to.
