This series adds initial support for the Samsung S2MPG10 PMIC using the MFD framework. This is a PMIC for mobile applications and is used on the Google Pixel 6 and 6 Pro (oriole / raven). *** dependency note *** To compile, this depends on the Samsung ACPM driver in Linux next with the following additional patches: https://lore.kernel.org/all/20250324-acpm-atomic-v2-0-7d87746e1765@linaro.org/ https://lore.kernel.org/all/20250319-acpm-fixes-v2-0-ac2c1bcf322b@linaro.org/ https://lore.kernel.org/all/20250327-acpm-children-v1-0-0afe15ee2ff7@linaro.org/ *** dependency note end *** +++ Kconfig update +++ There is a Kconfig symbol update in this series, because the existing Samsung S2M driver has been split into core and transport (I2C & ACPM) parts. CONFIG_MFD_SEC_CORE is now truly a core driver, and the I2C code that was part of it is now enabled via CONFIG_MFD_SEC_I2C. This was necessary because unlike the other S2M PMICs, S2MPG10 doesn't talk via I2C, but via the Samsung ACPM firmware. +++ Kconfig update end +++ This series must be applied in-order, due to interdependencies of some of the patches. There are also various cleanup patches to the S2M drivers. I've kept them ordered as: * DT bindings (patches 1 ... 3) * s2m mfd prep for adding S2MPG10 support (patches 4 ... 7) * split S2M mfd driver into s2m-core and s2m-i2c, including the kconfig symbol update (patch 8) * S2MPG10 core driver (patch 9) * s2m mfd driver cleanup patches (patches 10 ... 23) * S2MPG10 clock driver (patch 24) * s2m RTC prep for adding S2MPG10 (patch 25 ... 26) * S2MPG10 RTC driver (patch 27) * s2m RTC cleanup patches (patches 28 ... 31) I realise these are many, but since some prep-work was required to be able to add S2MPG anyway, I wanted to get the cleanup patches in as well :-) Let me know if I should postpone them to a later date instead. The S2MPG10 includes buck converters, various LDOs, power meters, RTC, clock outputs, and additional GPIOs interfaces. This series adds support in the top-level device driver, and for the RTC and clock. Importantly, having the RTC driver allows to do a proper reset of the system. Drivers or driver updates for the other components will be added in future patches. This will need a DT update for Oriole / Raven to enable this device. I will send that out separately.
