由 MyungJoo Ham 提交于
This patch supports PMIC/Regulator part of MAX8997/MAX8966 MFD. In this initial release, selecting voltages or current-limit and switching on/off the regulators are supported. Controlling voltages for DVS with GPIOs is not implemented fully and requires more considerations: it controls multiple bucks (selection of 1, 2, and 5) at the same time with SET1~3 gpios. Thus, when DVS-GPIO is activated, we lose the ability to control the voltage of a single buck regulator independently; i.e., contolling a buck affects other two bucks. Therefore, using the conventional regulator framework directly might be problematic. However, in this driver, we try to choose a setting without such side effect of affecting other regulators and then try to choose a setting with the minimum side effect (the sum of voltage changes in other regulators). On the other hand, controlling all the three bucks simultenously based on the voltage set table may help build cpufreq and similar system more robust; i.e., all the three voltages are consistent every time without glitches during transition.

MAX8952 PMIC is used to provide voltage output between 770mV - 1400mV with DVS support. In this initial release, users can set voltages for four DVS modes, RAMP delay values, and SYNC frequency. Controlling FPWM/SYNC_MODE/Pull-Down/Ramp Modes and reading CHIP_ID is not supported in this release. If GPIO of EN is not valid in platform data, the driver assumes that it is always-on. If GPIO of VID0 or VID1 is invalid, the driver pulls down VID0 and VID1 to fix DVS mode as 0 and disables DVS support. We assume that V_OUT is capable to provide every voltage from 770mV to 1.40V in 10mV steps although the data sheet has some ambiguity on it.

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.

Support most of the LDO regulators in the twl4030 family chips. In the case of LDOs supporting MMC/SD, the voltage controls are used; but in most other cases, the regulator framework is only used to enable/disable a supplies, conserving power when a given voltage rail is not needed. The drivers/mfd/twl4030-core.c code already sets up the various regulators according to board-specific configuration, and knows that some chips don't provide the full set of voltage rails. The omitted regulators are intended to be under hardware control, such as during the hardware-mediated system powerup, powerdown, and suspend states. Unless/until software hooks are known to be safe, they won't be exported here. These regulators implement the new get_status() operation, but can't realistically implement get_mode(); the status output is effectively the result of a vote, with the relevant hardware inputs not exposed.
