Change the logic for selecting pmic_children_info to use the compatible string from the devicetree instead of expecting the pwrap (part of the MCU) to correspond to the separate PMIC chip. In addition to being more correct, it also saves a few lines of code for each MCU type that is added by dropping the enum and type field.

Drop the PWRAP_SLV_CAP_DUALIO flag from the mt6359 PMIC definition. The mt6359p variant of the PMIC does support dual I/O. Prior to this change, the driver would attempt to write to the PWRAP_DEW_DIO_EN register, which was not defined, so would write register 0 (DONE2).

Add a PWRAP_CAP_INIT capability flag to specify if it is safe to call pwrap_init() or not. Not all targets define the registers accessed by pwrap_init(). In that case, it is expected that an earlier bootloader has already initialized the PMIC. If not, we now return an error instead of trying to access undefined registers.

The family of PCA9450 PMICs have the ability to perform system resets. Restarting via PMIC is preferred method of restarting the system as all the peripherals are brought to a know state after a power-cycle. The PCA9450 features a cold restart procedure which is initiated by an I2C command 0x14 to the SW_RST register. Support in Linux for restarting via PCA9450 PMIC has been added by Linux commit 6157e62b07d9 ("regulator: pca9450: Add restart handler").

2025-08-30power: rk8xx: allow to customize RK806 reset modeQuentin Schulz
The RK806 PMIC has a bitfield for configuring the restart/reset behavior (which I assume Rockchip calls "function") whenever the PMIC is reset either programmatically (c.f. DEV_RST in the datasheet) or via PWRCTRL or RESETB pins. For RK806, the following values are possible for RST_FUN: 0b00 means "Restart PMU" 0b01 means "Reset all the power off reset registers, forcing the state to switch to ACTIVE mode" 0b10 means "Reset all the power off reset registers, forcing the state to switch to ACTIVE mode, and simultaneously pull down the RESETB PIN for 5mS before releasing" 0b11 means the same as for 0b10 just above. This adds the appropriate logic in the driver to parse the new rockchip,reset-mode DT property to pass this information. It just happens that the values in the binding match the values to write in the bitfield so no mapping is necessary. For backward compatibility reasons, if the property is missing we set it to 0b10 (i.e. BIT(7)) like before this commit was merged instead of leaving it untouched like in the kernel driver. Note that this does nothing useful for U-Boot at the moment as the ways to reset the device (e.g. via `reset` command) doesn't interact with the RK8xx PMIC and simply does a CPU reset. Considering the upstream Linux kernel left this register untouched until (assumed) v6.17[1], this is useful for cases in which the U-Boot bootloader has this patch (and running with a DT with rockchip,reset-mode property set) and running an upstream kernel before (assumed) v6.17, or alternatively later without the property in the kernel DT.

2025-06-06power: rk8xx: fix swapped mask and value in init registers for RK806Quentin Schulz
The val (the bits to set) is the second member of the reg_data structure and mask the third one. We obviously want to clear bits 6 and 7 in order to only set bit 7 in there instead of only clearing bit 7 in order to write bits 6 and 7 (which makes no sense). Fortunately, according to the datasheet, bit 6 value doesn't matter when bit 7 is set so this is essentially just a cosmetic change, no intended change in behavior.

2024-10-11Merge patch series "Tidy up use of 'SPL' and CONFIG_SPL_BUILD"Tom Rini
Simon Glass <[email protected]> says: When the SPL build-phase was first created it was designed to solve a particular problem (the need to init SDRAM so that U-Boot proper could be loaded). It has since expanded to become an important part of U-Boot, with three phases now present: TPL, VPL and SPL Due to this history, the term 'SPL' is used to mean both a particular phase (the one before U-Boot proper) and all the non-proper phases. This has become confusing. For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL' phases, not just SPL. So code which can only be compiled for actual SPL, for example, must use something like this: #if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD) In Makefiles we have similar issues. SPL_ has been used as a variable which expands to either SPL_ or nothing, to chose between options like CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable was created which expanded to 'SPL_', 'TPL_' or nothing. Later it was updated to support 'VPL_' as well. This series starts a change in terminology and usage to resolve the above issues: - The word 'xPL' is used instead of 'SPL' to mean a non-proper build - A new CONFIG_XPL_BUILD define indicates that the current build is an 'xPL' build - The existing CONFIG_SPL_BUILD is changed to mean SPL; it is not now defined for TPL and VPL phases - The existing SPL_ Makefile variable is renamed to SPL_ - The existing SPL_TPL Makefile variable is renamed to PHASE_ It should be noted that xpl_phase() can generally be used instead of the above CONFIGs without a code-space or run-time penalty. This series does not attempt to convert all of U-Boot to use this new terminology but it makes a start. In particular, renaming spl.h and common/spl seems like a bridge too far at this point. The series is fully bisectable. It has also been checked to ensure there are no code-size changes on any commit.
