dm: regulator: add implementation of driver model regulator uclass This commit introduces the implementation of dm regulator API. Device tree support allows for auto binding. And by the basic uclass operations, it allows to driving the devices in a common way. For detailed informations, please look into the header file. Core files: - drivers/power/regulator-uclass.c - provides regulator common functions api - include/power/regulator.h - define all structures required by the regulator Changes: - new uclass-id: UCLASS_REGULATOR - new config: CONFIG_DM_REGULATOR Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Acked-by: Simon Glass <sjg@chromium.org>

---help---
This config enables the driver model regulator support.
UCLASS_REGULATOR - designed to provide a common API for basic regulator's
functions, like get/set Voltage or Current value, enable state, etc...
Note:
When enabling this, please read the description, found in the files:
- 'include/power/pmic.h'
- 'include/power/regulator.h'
- 'drivers/power/pmic/pmic-uclass.c'
- 'drivers/power/pmic/regulator-uclass.c'
It's important to call the device_bind() with the proper node offset,
when binding the regulator devices. The pmic_bind_childs() can be used

regulator: bd718x7: support ROHM BD71837 and BD71847 PMICs BD71837 and BD71847 is PMIC intended for powering single-core, dual-core, and quad-core SoC’s such as NXP-i.MX 8M. BD71847 is used for example on NXP imx8mm EVK. Add regulator driver for ROHM BD71837 and BD71847 PMICs. BD71837 contains 8 bucks and 7 LDOS. BD71847 is reduced version containing 6 bucks and 6 LDOs. Voltages for DVS bucks (1-4 on BD71837, 1 and 2 on BD71847) can be adjusted when regulators are enabled. For other bucks and LDOs we may have over- or undershooting if voltage is adjusted when regulator is enabled. Thus this is prevented by default. BD718x7 has a quirk which may leave power output disabled after reset if enable/disable state was controlled by SW. Thus the SW control is only allowed for BD71837 bucks 3 and 4 by default. The impact of this limitation must be evaluated board-by board and restrictions may need to be modified. (Linux driver get's these limitations from DT and we may want to implement same on u-Boot driver).

power: add FAN53555 family support This adds a driver for the FAN53555 family of regulators and wraps it in a PMIC implementation. While these devices support a 'normal' and 'suspend' mode (controlled via an external pin) to switch between two programmable voltages, this incarnation of the driver assumes that the device is always operating in 'normal' mode. Only setting/reading the programmed voltage is supported at this time and the following device functionality remains unsupported: - switching the selected voltage (via a GPIO) - disabling the voltage output via software-control This matches the functionality of the Linux driver. Tested on a RK3399-Q7 (with 'option 5' devices): setting voltages from the U-Boot shell and verifying output voltages on the board.

sandbox: add: sandbox PMIC device drivers: I2C emul, pmic, regulator This commit adds emulation of sandbox PMIC device, which includes: - PMIC I2C emulation driver - PMIC I/O driver (UCLASS_PMIC) - PMIC regulator driver (UCLASS_REGULATOR) The sandbox PMIC has 12 significant registers and 4 as padding to 16 bytes, which allows using 'i2c md' command with the default count (16). The sandbox PMIC provides regulators: - 2x BUCK - 2x LDO Each, with adjustable output: - Enable state - Voltage - Current limit (LDO1/BUCK1 only) - Operation mode (different for BUCK and LDO) Each attribute has it's own register, beside the enable state, which depends on operation mode. The header file: sandbox_pmic.h includes PMIC's default register values, which are set on i2c pmic emul driver's probe() method.

Enable the regulator driver for emulated Sandbox PMIC.
The emulated PMIC device depends on two drivers:
- sandbox PMIC I/O driver - implements dm pmic operations
- sandbox PMIC regulator driver - implements dm regulator operations
- sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission
The regulator driver provides uclass operations for sandbox PMIC's
regulators. The driver implements get/set api for: voltage, current,
operation mode and enable state.
The driver supports LDO and BUCK regulators.
The Sandbox PMIC info:
* I/O interface:
- I2C chip address: 0x40
- first register address: 0x0
- register count: 0x10
* Adjustable outputs:
- 2x LDO
- 2x BUCK
- Each, with a different operating conditions (header).
* Reset values:
- set by i2c emul driver's probe() (defaults in header)
A detailed information can be found in header: '<power/sandbox_pmic.h>'
