2020-01-28power: pmic: add driver for Dialog DA9063 PMICMartin Fuzzey1-0/+1
This adds the basic register access operations and child regulator binding (if a regulator driver exists). Robert Beckett: simplify accesses by using bottom bit of address as offset overflow. This avoids the need to track which page we are on. Add an option CONFIG_SPL_DM_PMIC_DA9063.

2018-12-10power: add FAN53555 family supportPhilipp Tomsich1-0/+1
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.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-3/+1
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

Texas Instrument's TPS65910 PMIC contains 3 buck DC-DC converts, one boost DC-DC converter and 8 LDOs. This patch implements driver model support for the TPS65910 PMIC and its regulators making the get/set API for regulator value/enable available. This patch depends on the patch "am33xx: Add a function to query MPU voltage in uV" to build correctly. For boards relying on the DT include file tps65910.dtsi the v3 patch "power: extend prefix match to regulator-name property" and an appropriate regulator naming is also required.

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.

2015-05-15dm: pmic: add max77686 pmic driverPrzemyslaw Marczak1-0/+1
This is the implementation of driver model PMIC driver. The max77686 PMIC driver implements read/write operations and driver bind method - to bind its childs. This driver will try to bind the regulator devices by using it's child info array with regulator prefixes and driver names. This should succeed when compatible regulator driver is compiled. If no regulator driver found, then the pmic can still provide read/write operations, and can be used with PMIC function calls.

2015-05-15dm: pmic: add implementation of driver model pmic uclassPrzemyslaw Marczak1-0/+1
This commit introduces the PMIC uclass implementation. It allows providing the basic I/O interface for PMIC devices. For the multi-function PMIC devices, this can be used as I/O parent device, for each IC's interface. Then, each PMIC particular function can be provided by the child device's operations, and the child devices will use its parent for read/write by the common API. Core files: - 'include/power/pmic.h' - 'drivers/power/pmic/pmic-uclass.c' The old pmic framework is still kept and is independent. For more detailed informations, please look into the header file.
