2013-12-02regulator: tps6586x: fixed voltage table for TPS658643Stefan Agner
The voltage table for the SM2 regulator on TPS658643 was wrong. However, since the requested voltage of 1.8V was at the right place, the system worked fine nonetheless.

2012-07-17regulator: tps6586x support for tps658623 and tps658643Marcel Ziswiler
From a regulator point of view those PMICs differentiate in their SM2 voltage tables. While the older tps658621a and tps658621d as utilised on Harmony resp. Ventana have a range from 3000 to 4550 mV the tps658623 goes from 1700 to 2475 mV and the tps658643 just from 1025 to 1800 mV. Using its VERSIONCRC register the type of PMIC is queried and the right ranges applied.
2012-07-02regulator: tps80031: support for min voltage toleranceLaxman Dewangan
Sometimes the system allow to run in less than requested minimum voltage and if this tolerance allow the regulator to set voltage in lower side range than this saves the power. For the example, if client request vmin = 975mV for regulator voltage then it sets the voltage to 987.5mv as the nearest to this desired value. The next lower side for the voltage is 974.8mv. So if system runs on tolerance of 1mv and if it request for 975mv then driver can look for minimum voltage as 975 - tolerance(1) = 974mv and possible configure 974.8mv rather than 987.5mV and so it can save the power equivalent to 12.5mV higher voltage. Support the configuration of tolerance value.
