2019-03-21regulator: tps65217: Simplify linear range for selector 25-52Axel Lin
The original code separates the selector 25-52 into 2 ranges on purpose because DCDC1/DCDC3 only support up to 1.8V/1.5V in the old code. Both DCDC1 and DCDC3 support up to 3.3V since commit b4c2e158a1e1 ("regulator: tps65217: Allow DCDC1 and DCDC3 up to 3.3V"), so merge 25-30 and 31-52 ranges to one range.

2019-03-19regulator: core: fix error path for regulator_set_voltage_unlockedSteve Twiss
During several error paths in the function regulator_set_voltage_unlocked() the value of 'ret' can take on negative error values. However, in calls that go through the 'goto out' statement, this return value is lost and return 0 is used instead, indicating a 'pass'. There are several cases where this function should legitimately return a fail instead of a pass: one such case includes constraints check during voltage selection in the call to regulator_check_voltage(), which can have -EINVAL for the case when an unsupported voltage is incorrectly requested. In that case, -22 is expected as the return value, not 0.

2019-03-18regulator: core: Fix application of "drop lockdep annotation in ↵Mark Brown
drms_uA_update()" [The original commit was sent against -next but needed to be sent as a bugfix, however -next had some additional changes which needed to be reverted. Now everything is all in one branch applying the rest of the changes to fix up the merge issue -- broonie] commit e5e21f70bfd3 ("regulator: core: Take lock before applying system load") took the regulator lock before calling drms_uA_update() in order to silence a lockdep warning during regulator_register(). However, we are not supposed to need locks at this point as the regulator is in the process of being registered, so there should be no possibility of concurrent access. Instead, remove the unnecessary locking and simply drop the lockdep annotation, since it is no longer valid.
