| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a system has said that it has fully specified constraints for its regulators it is still possible that some supplies may be missing, especially if regulator support has been added to a driver after the board was integrated. We can handle such situations more gracefully by providing a dummy regulator. Unless the caller has specifically indicated that the system design may not include a given regulator by using regulator_get_optional() or that it needs its interactions to have an effect using regulator_get_exclusive() provide a dummy regulator if we can't locate a real one. The kconfig option REGULATOR_DUMMY that provided similar behaviour for all regulators has been removed, systems that need it should flag that they have full constraints instead.

| * regulator: Introduce TI Adaptive Body Bias(ABB) on-chip LDO driverAndrii.Tseglytskyi2013-05-121-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adaptive Body Biasing (ABB) modulates transistor bias voltages dynamically in order to optimize switching speed versus leakage. Texas Instruments' SmartReflex 2 technology provides support for this power management technique with Forward Body Biasing (FBB) and Reverse Body Biasing (RBB). These modulate the body voltage of transistor cells or blocks dynamically to gain performance and reduce leakage. TI's SmartReflex white paper[1] has further information for usage in conjunction with other power management techniques. The application of FBB/RBB technique is determined for each unique device in some process nodes, whereas, they are mandated on other process nodes. In a nutshell, ABB technique is implemented on TI SoC as an on-chip LDO which has ABB module controlling the bias voltage. However, the voltage is unique per device. These vary per SoC family and the manner in which these techniques are used may vary depending on the Operating Performance Point (OPP) voltage targeted. For example: OMAP3630/OMAP4430: certain OPPs mandate usage of FBB independent of devices. OMAP4460/OMAP4470: certain OPPs mandate usage of FBB, while others may optionally use FBB or optimization with RBB. OMAP5: ALL OPPs may optionally use ABB, and ABB biasing voltage is influenced by vset fused in s/w and requiring s/w override of default values. Further, two generations of ABB module are used in various TI SoCs. They have remained mostly register field compatible, however the register offset had switched between versions. We introduce ABB LDO support in the form of a regulator which is controlled by voltages denoting the desired Operating Performance Point which is targeted. However, since ABB transition is part of OPP change sequence, the sequencing required to ensure sane operation w.r.t OPP change is left to the controlling driver (example: cpufreq SoC driver) using standard regulator operations. The driver supports all ABB modes and ability to override ABB LDO vset control efuse based ABB mode detection etc. Current implementation is heavily influenced by the original patch series [2][3] from Mike Turquette. However, the current implementation supports only device tree based information.

Advanced features such as D-Cap+ architecture with overlapping pulse support and OSR overshoot reduction provide fast transient response, lowest output capacitance and high efficiency. The TPS51632 supports both I2C and DVFS interfaces (through PWM) for dynamic control of the output voltage and current monitor telemetry. Add regulator driver for TPS51632.
