2021-10-25power: pmic: axp: Implement poweroff via sysresetSamuel Holland2-1/+50
The AXP PMICs have the ability to power off the system. The existing code for this is duplicated for each PMIC variant, and uses the legacy non-DM "pmic_bus" interface. When SYSRESET is enabled, this can all be replaced with a sysreset device using the DM_PMIC interface. Since the trigger bit is the same on all PMIC variants, use the register definitions from the oldest supported PMIC.

The bulk of it is Samuel's DM_I2C rework, which removes the nasty I2C deprecation warnings for most 32-bit boards. It also includes some smaller refactorings that pave the way for more changes, mostly driven by needing to support the Allwinner RISC-V SoC later on. Board wise we gain support for the FriendlyARM NanoPi R1S H5 router board and official Pinetab support. Build-tested for all 160 sunxi boards, and boot tested on a A64, A20, H3, H6, and H616 board. USB, SD card, eMMC, and Ethernet all work there (where applicable).
2021-10-12power: pmic: Add a driver for X-Powers AXP PMICsSamuel Holland3-0/+53
These PMICs provide some combination of battery charger, fuel gauge, GPIOs, regulators, and VBUS routing. These functions are represented as child nodes in the device tree. Add the minimal driver needed to probe these child devices and provide the DM_PMIC ops. Enable the driver by default for SoCs that normally pair with a PMIC.

Kconfig symbols for two PMIC drivers (PMIC_AS3722 and DM_PMIC_MC34708) were missing a dependency on DM_PMIC. To fix this inconsistency, and to keep it from happening again, wrap the driver section with "if DM_PMIC" instead of using a "depends on DM_PMIC" clause for each driver.

2021-07-14power: pmic: Add driver for ST-Ericsson AB8500 via PRCMUStephan Gerhold3-0/+279
All devices based on ST-Ericsson Ux500 use a PMIC similar to AB8500 (Analog Baseband). There is AB8500, AB8505, AB9540 and AB8540 although in practice only AB8500 and AB8505 are relevant since the platforms with AB9540 and AB8540 were cancelled and never used in production. In general, the AB8500 PMIC uses I2C as control interface, where the different register banks are represented as separate I2C devices. However, in practice AB8500 is always connected to a special I2C bus on the DB8500 SoC that is controlled by the power/reset/clock management unit (PRCMU) firmware. Add a simple driver that allows reading/writing registers of the AB8500 PMIC. The driver directly accesses registers from the PRCMU parent device (represented by syscon in U-Boot). Abstracting it further (e.g. with the i2c uclass) would not provide any advantage because the PRCMU I2C bus is always just connected to AB8500 and vice-versa. The ab8500.h header is mostly taken as-is from Linux (with some minor adjustments) to allow using similar code in both Linux and U-Boot.

CONFIG_IS_ENABLED(DM_I2C) expands to: - 1 if CONFIG_SPL_BUILD is undefined and CONFIG_DM_I2C is set to 'y', - 1 if CONFIG_SPL_BUILD is defined and CONFIG_SPL_DM_I2C is set to 'y', - 0 otherwise.

We use the U_BOOT_ prefix (i.e. U_BOOT_DRIVER) to declare a driver but in every other case we just use DM_. Update the alias macros to use the DM_ prefix. We could perhaps rename U_BOOT_DRIVER() to DM_DRIVER(), but this macro is widely used and there is at least some benefit to indicating it us a U-Boot driver, particularly for code ported from Linux.

2020-07-10core: add support for U_BOOT_DRIVER_ALIASWalter Lozano1-0/+2
Currently when using OF_PLATDATA the binding between devices and drivers is done trying to match the compatible string in the node with a driver name. However, usually a single driver supports multiple compatible strings which causes that only devices which its compatible string matches a driver name get bound. To overcome this issue, this patch adds the U_BOOT_DRIVER_ALIAS macro, which generates no code at all, but allows an easy way to declare driver name aliases. Thanks to this, dtoc could be improve to look for the driver name based on its alias when it populates the U_BOOT_DEVICE entry.
