2010-03-07mfd: Support 88pm8606 in 860x driverHaojian Zhuang
88PM8606 and 88PM8607 are two discrete chips used for power management. Hardware designer can use them together or only one of them according to requirement. There's some logic tightly linked between these two chips. For example, USB charger driver needs to access both chips by I2C interface. Now share one driver to these two devices. Only one I2C client is identified in platform init data. If another chip is also used, user should mark it in companion_addr field of platform init data. Then driver could create another I2C client for the companion chip. All I2C operations are accessed by 860x-i2c driver. In order to support both I2C client address, the read/write API is changed in below. reg_read(client, offset) reg_write(client, offset, data) The benefit is that client drivers only need one kind of read/write API. I2C and MFD driver can be shared in both 8606 and 8607. Since API is changed, update API in 8607 regulator driver.

2010-03-03regulator: Provide optional dummy regulator for consumersMark Brown
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.

2010-03-03regulator: mc13783: consider Power Gates as digital regulators.Alberto Panizzo
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.

2010-03-03regulator: Allow regulators to specify the time taken to ramp on enableMark Brown
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.

2010-03-03regulator: Add notifier event on regulator disableMark Brown
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.

2009-12-17regulator: mc13783-regulator: correct the probing time.Alberto Panizzo
When the mc13783-regulator driver is built in kernel, probing it during the regulator subsystem initialisation result in a fault. That is because regulator subsystem is planned to be initialised very early in the boot process, before the mfd subsystem initialisation. The mc12783-regulator probing process need to access to the mc13783-core functionality to read/write mc13783 registers and so must be called after the mc13783-core driver initialisation. The way to do this is to let the kernel probe the mc13783-regulator driver when mc13783-core register his regulator subdevice.
