As exposed by "make randconfig", we have an issue around how SYSRESET_CMD_POWEROFF is typically selected. We cannot rely only on CMD_POWEROFF as SYSRESET_CMD_POWEROFF must also be tested for its own dependency of SYSRESET. Signed-off-by: Tom Rini <trini@konsulko.com>
Add a condition to enable the PMIC sysreset function via the system-power-controller device tree property in addition to the existing Kconfig dependency, provided the PMIC supports it.

The Linux kernel CPCAP driver uses uppercase regulator node names, while this driver uses lowercase. Since regulator names can be case-insensitive, update the driver to support both uppercase and lowercase node names. Signed-off-by: Svyatoslav Ryhel <clamor95@gmail.com>

Add support for the PMIC wrapper (pwrap) IP block found on MediaTek MT8365 and similar SoCs. On these SoCs the PMIC is connected via SPI. The SPI controller is not directly visible to the CPU, but only through the PMIC wrapper inside the SoC.

Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and drop the unnecessary inclusion of asm/global_data.h. Headers should be included directly by the files that need them, rather than indirectly via global_data.h.

The PMIC is also known as AXP819 in vendor pmu code For DCDC6, 8, 9, the underlying hardware support more than two levels voltage step tuning, but for now only first two levels are implemented in this driver, hence highest voltage will be limited at seccond level. It actual meets board requirement in current design, and we've verified it in Radxa Cubie A7A board. Following are detail explanation of voltage tuning stpes for those DCDCs: DCDC | voltage range | units | steps | implemented 6 | 0.5 - 1.2 | 10 mV | 71 | Y . | 1.22 - 1.54 | 20 mV | 17 | Y . | 1.8 - 2.4 | 20 mV | 31 | N . | 2.44 - 2.76 | 40 mV | 9 | N -------------------------------------------------- 8/9 | 0.5 - 1.2 | 10 mV | 71 | Y . | 1.22 - 1.84 | 20 mV | 32 | Y . | 1.9 - 3.4 | 100mV | 16 | N Signed-off-by: Yixun Lan <dlan@gentoo.org> Reviewed-by: Andre Przywara <andre.przywara@arm.com>

There are multiple PMICs by Samsung which are similar in architecture (register layout, interface, etc.) and is possible to be driven by a single driver. Variant specific code and data should be managed properly in the driver. And an enum which describes all supported variants. Pass the enum as the device driver data. Introduce a switch-case block on the enum for any variant specific code.

The probe function, s2mps11_probe() is responsible for binding its PMIC children. The driver doesn't have any functionality directly, but has sub-devices which are parts of the device. Therefore, this should be a bind function. This is the case in the Samsung S5M8767 PMIC driver.
