* Regulators: lp3971 - fail if platform data was not suppliedDmitry Torokhov2010-03-031-29/+29
| | | | | | | | | | | | | There is no point in completing probe if platform data is missing so let's abort loading early. Also, use kcalloc when allocating several instances of the same data structure and mark setup_regulators() as __devinit since it is only called from lp3971_i2c_probe() which is __devinit.

* regulator: Provide optional dummy regulator for consumersMark Brown2010-03-035-1/+135
| | | | | | | | | | | | | | | | | | | | | | | | In order to ease transitions with drivers are boards start using regulators provide an option to cause all regulator_get() calls to succeed, with a dummy always on regulator being supplied where one has not been configured. A warning is printed whenever the dummy regulator is used to aid system development. This regulator does not implement any regulator operations but will allow simple consumers which only do enable() and disable() calls to run. It is kept separate from the fixed voltage regulator to avoid Kconfig confusion on the part of users when it is extended to allow boards to explicitly use the dummy regulator to simplify cases where the majority of supplies are from fixed regulators without software control. This option is currently only effective for systems which do not specify full constriants. If required an override could also be provided to allow these systems to use the dummy regulator, though it is likely that unconfigured supplies on such systems will lead to error due to regulators being powered down more aggressively when not in use.

* regulator: mc13783: consider Power Gates as digital regulators.Alberto Panizzo2010-03-032-6/+128
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GPO regulators are digital outputs that can be enabled or disabled by a dedicated bit in mc13783 POWERMISC register. In this family can be count in also Power Gates (PWGT1 and 2): enabled by a dedicated pin a Power Gate is an hardware driven supply where the output (PWGTnDRV) follow this law: Bit PWGTxSPIEN | Pin PWGTxEN | PWGTxDRV | Read Back 0 = default | | | PWGTxSPIEN ---------------+-------------+----------+------------ 1 | x | Low | 0 0 | 0 | High | 1 0 | 1 | Low | 0 As read back value of control bit reflects the PWGTxDRV state (not the control value previously written) and mc13783 POWERMISC register contain only regulator related bits, a dedicated function to manage these bits is created here with the aim of tracing the real value of PWGTxSPIEN bits and reproduce it on next writes. All POWERMISC users _must_ use the new function to not accidentally disable Power Gates supplies. v2 changes: -Better utilization of abstraction layers. -Voltage query support. GPO's and PWGTxDRV are fixed voltage regulator with voltage value of 3.1V and 5.5V respectively.

* regulator: Allow regulators to specify the time taken to ramp on enableMark Brown2010-03-032-6/+41
| | | | | | | | | | | | | | | | | Regulators may sometimes take longer to enable than the control operation used to do so, either because the regulator has ramp rate control used to limit inrush current or because the control operation is very fast (GPIO being the most common example of this). In order to ensure that consumers do not rely on the regulator before it is enabled provide an enable_time() operation and have the core delay for that time before returning to the caller. This is implemented as a function since the ramp rate may be specified in voltage per unit time and therefore the time depend on the configuration. In future it would be desirable to allow the bulk operations to run the delays for multiple enables in parallel but this is not currently supported.

* regulator: Add notifier event on regulator disableMark Brown2010-03-032-3/+8
| | | | | | | | | | | The intended use case is for drivers which disable regulators to save power but need to do some work to restore the hardware state when restarting. If the supplies are not actually disabled due to board limits or sharing with other active devices this notifier allows the driver to avoid unneeded reinitialisation, particularly when used with runtime PM.
