If called +when enabled, then the voltage changes instantly, otherwise the voltage +configuration changes and the voltage is physically set when the regulator is +next enabled. + +The regulators configured voltage output can be found by calling :- + +int regulator_get_voltage(regulator); + +NOTE: get_voltage() will return the configured output voltage whether the +regulator is enabled or disabled and should NOT be used to determine regulator +output state.

Regulator Operating Mode Control & Status (dynamic drivers) +============================================================= + +Some consumers can further save system power by changing the operating mode of +their supply regulator to be more efficient when the consumers operating state +changes. e.g. consumer driver is idle and subsequently draws less current + +Regulator operating mode can be changed indirectly or directly. + +Indirect operating mode control. +-------------------------------- +Consumer drivers can request a change in their supply regulator operating mode +by calling :- + +int regulator_set_optimum_mode(struct regulator *regulator, int load_uA); + +This will cause the core to recalculate the total load on the regulator (based +on all it's consumers) and change operating mode (if necessary and permitted) +to best match the current operating load. + +The load_uA value can be determined from the consumers datasheet. e.g.most +datasheets have tables showing the max current consumed in certain situations. + +Most consumers will use indirect operating mode control since they have no +knowledge of the regulator or whether the regulator is shared with other +consumers. + +Direct operating mode control. +------------------------------ +Bespoke or tightly coupled drivers may want to directly control regulator +operating mode depending on their operating point.

Constraints exist at three levels: + + Regulator Level: This is defined by the regulator hardware + operating parameters and is specified in the regulator + datasheet. i.e. + + - voltage output is in the range 800mV -> 3500mV. + - regulator current output limit is 20mA @ 5V but is + 10mA @ 10V. + + Power Domain Level: This is defined in software by kernel + level board initialisation code. It is used to constrain a + power domain to a particular power range. i.e. + + - Domain-1 voltage is 3300mV + - Domain-2 voltage is 1400mV -> 1600mV + - Domain-3 current limit is 0mA -> 20mA. + + Consumer Level: This is defined by consumer drivers + dynamically setting voltage or current limit levels. + + e.g. a consumer backlight driver asks for a current increase + from 5mA to 10mA to increase LCD illumination. This passes + to through the levels as follows :- + + Consumer: need to increase LCD brightness.

Consumer driver interface. + + This uses a similar API to the kernel clock interface in that consumer + drivers can get and put a regulator (like they can with clocks atm) and + get/set voltage, current limit, mode, enable and disable. This should + allow consumers complete control over their supply voltage and current + limit. This also compiles out if not in use so drivers can be reused in + systems with no regulator based power control. + + See Documentation/power/regulator/consumer.txt + + 2. Regulator driver interface. + + This allows regulator drivers to register their regulators and provide + operations to the core. It also has a notifier call chain for propagating + regulator events to clients. + + See Documentation/power/regulator/regulator.txt + + 3. Machine interface. + + This interface is for machine specific code and allows the creation of + voltage/current domains (with constraints) for each regulator. It can + provide regulator constraints that will prevent device damage through + overvoltage or over current caused by buggy client drivers. It also + allows the creation of a regulator tree whereby some regulators are + supplied by others (similar to a clock tree). + + See Documentation/power/regulator/machine.txt + + 4.

Prior to this KVM - initialization, we choose to map virtual to physical addresses - 1:1. That is, the kernel virtual address exactly matches the - physical address on the bus. These mappings are typically done - in arch/ppc/kernel/head.S, or arch/ppc/mm/init.c. Only - absolutely necessary mappings should be done at this time, for - example board control registers or a serial uart. Normal device - driver initialization should map resources later when necessary. - - Although platform dependent, and certainly the case for embedded - 8xx, traditionally memory is mapped at physical address zero, - and I/O devices above physical address 0x80000000. The lowest - and highest (above 0xf0000000) I/O addresses are traditionally - used for devices or registers we need to map during kernel - initialization and prior to KVM operation. For this reason, - and since it followed prior PowerPC platform examples, I chose - to map the embedded 8xx kernel to the 0xc0000000 virtual address. - This way, we can enable the MMU to map the kernel for proper - operation, and still map a few windows before the KVM is operational. - - On some systems, you could possibly run the kernel at the - 0x80000000 or any other virtual address. It just depends upon - mapping that must be done prior to KVM operational. You can never - map devices or kernel spaces that overlap with the user virtual - space. This is why default IMMR mapping used by most BDM tools - won't work. They put the IMMR at something like 0x10000000 or - 0x02000000 for example. You simply can't map these addresses early - in the kernel, and continue proper system operation. - - The embedded 8xx/82xx kernel is mature enough that all you should - need to do is map the IMMR someplace at or above 0xf0000000 and it - should boot far enough to get serial console messages and KGDB - connected on any platform.
