regulator: Set PROBE_PREFER_ASYNCHRONOUS for drivers that existed in 4.14 Probing of regulators can be a slow operation and can contribute to slower boot times. This is especially true if a regulator is turned on at probe time (with regulator-boot-on or regulator-always-on) and the regulator requires delays (off-on-time, ramp time, etc). While the overall kernel is not ready to switch to async probe by default, as per the discussion on the mailing lists [1] it is believed that the regulator subsystem is in good shape and we can move regulator drivers over wholesale. There is no way to just magically opt in all regulators (regulators are just normal drivers like platform_driver), so we set PROBE_PREFER_ASYNCHRONOUS for all regulators found in 'drivers/regulator' individually. Given the number of drivers touched and the impossibility to test this ahead of time, it wouldn't be shocking at all if this caused a regression for someone. If there is a regression caused by this patch, it's likely to be one of the cases talked about in [1]. As a "quick fix", drivers involved in the regression could be fixed by changing them to PROBE_FORCE_SYNCHRONOUS. That being said, the correct fix would be to directly fix the problem that caused the issue with async probe. The approach here follows a similar approach that was used for the mmc subsystem several years ago [2]. In fact, I ran nearly the same python script to auto-generate the changes. The only thing I changed was to search for "i2c_driver", "spmi_driver", and "spi_driver" in addition to "platform_driver".

regulator: ab8500: Remove AB8505 USB regulator The USB regulator was removed for AB8500 in commit 41a06aa738ad ("regulator: ab8500: Remove USB regulator"). It was then added for AB8505 in commit 547f384f33db ("regulator: ab8500: add support for ab8505"). However, there was never an entry added for it in ab8505_regulator_match. This causes all regulators after it to be initialized with the wrong device tree data, eventually leading to an out-of-bounds array read. Given that it is not used anywhere in the kernel, it seems likely that similar arguments against supporting it exist for AB8505 (it is controlled by hardware). Therefore, simply remove it like for AB8500 instead of adding an entry in ab8505_regulator_match.

regulator: ab8500: Fix set voltage for AB8540_LDO_AUX3 When setting voltage for AB8540_LDO_AUX3, current code only updates one of info->voltage_reg and info->expand_register registers which is wrong. To ensure we set to correct voltage, it always needs to clear or set expand_register.voltage_mask bit of expand_register. The function of the expand register bit is the following (from the user manual): 0: VAUX3 output voltage is determined by Vaux3Sel bit settings in register VldoCVaux3Sel 1: VAUX3 output voltage is set to 3.05V regardless of Vaux3Sel settings in register VldoCVaux3Sel (VldoCVaux3Sel is the register at 0x0421) So when going to 3.05V, set the expand register bit. When leaving 3.05V for another voltage, set the target voltage before clearing the expand register bit.

regulator: ab8500: Get rid of is_enabled from struct ab8500_regulator_info The intention of this patch is to simplify the code. Maintain the is_enabled flag is not trivial, it not only needs to set/clear the flag in disable()/enable() but also needs to set the flag in is_enable() to get initial status. The only benefit of keeping is_enabled flag is just save a register read when set_mode(). Remove is_enabled flag makes the code simpler. This patch also moves ab8500_regulator_is_enabled() close to ab8500_regulator_[en|dis]able functions. This is required to avoid a forward declaration because now we call ab8500_regulator_is_enabled() in ab8500_regulator_set_mode().

By doing this we avoid needing to do further changes like the recent addition of device tree support which required each regulator driver to be updated to take an additional parameter. The regulator_desc which should (mostly) be static data is still passed separately as most drivers are able to configure this statically at build time.

regulator: Add module.h to drivers/regulator users as required Another group of drivers that are taking advantage of the implicit presence of module.h -- and will break when we pull the carpet out from under them during a cleanup. Fix 'em now. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

regulator: initialization for ab8500 regulators The regulators on the AB8500 have a lot of custom hardware control settings pertaining to 8 external signals, settings which are board-specific and need be provided from the platform at startup. Initialization added for regulators Vana, VextSupply1, VextSupply2, VextSupply3, Vaux1, Vaux2, Vaux3, VTVout, Vintcore12, Vaudio, Vdmic, Vamic1, Vamic2, VrefDDR.

regulators: Fixed errors in ab8500 register mapping For INTCORE and TVOUT regulators, the low power register bit is included in the mask so that enable will set the regulator in normal (high power) mode. ANAMIC1, ANAMIC2, DMIC regulator settings are swapped with each other so that the correct regulator gets enabled/disabled. ANA regulator register address is corrected.

regulators: Moved define for number of regulators in ab8500 The define for number of regulators is moved from ab8500-core to ab8500-regulator so that the regulator driver can be updated independently of ab8500-core. This also changes the platform configuration structure of ab8500-core so that it contains a pointer to the regulator_init_data array plus number of regulators instead of an fixed size array of pointers to regulator_init_data.

regulator: Report actual configured voltage to set_voltage() Change the interface used by set_voltage() to report the selected value to the regulator core in terms of a selector used by list_voltage(). This allows the regulator core to know the voltage that was chosen without having to do an explict get_voltage(), which would be much more expensive as it will generally access hardware.
