| * regulator: ab8500: Remove SYSCLKREQ from enum ab8505_regulator_idStephan Gerhold2020-01-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 458ea3ad033fc86e291712ce50cbe60c3428cf30 upstream. Those regulators are not actually supported by the AB8500 regulator driver. There is no ab8500_regulator_info for them and no entry in ab8505_regulator_match. As such, they cannot be registered successfully, and looking them up in ab8505_regulator_match causes an out-of-bounds array read.

| * regulator: Fix return value of _set_load() stubMark Brown2019-12-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit f1abf67217de91f5cd3c757ae857632ca565099a ] The stub implementation of _set_load() returns a mode value which is within the bounds of valid return codes for success (the documentation just says that failures are negative error codes) but not sensible or what the actual implementation does. Fix it to just return 0.

| | | | | | | | | | | | | | | | | | | | | | | | | | Since the regulator debugfs consumer does not call regulator_allow_bypass() on its regulator handles, regulators will not be placed on bypass mode even if all other consumers request for this. Fix this by introducing an open offset count that can be used to selectively disregard the debugfs consumer. Also, introduce a debugfs file to allow or disallow bypass mode on each regulator by leveraging on the new open offset count.

Add another routine regulator_set_voltage_triplet(), which accepts target, min and max voltages as arguments. This first tries to set the voltage between the target voltage and the upper limit, then fall back on the full range. The idea behind this is to set regulator's voltage as close to the target voltage, as possible. Based on regulator_set_voltage_tol().
