I understand the concern regarding mixing subsystems, and I apologize for the extra overhead this caused during review. The decision to group these was driven by tight functional inter-dependencies that I felt would have caused build failures or regressions if split: MFD & Charger: The charger driver relies on new macros and symbols defined in mfd/max77759.h. Additionally, the MFD driver handles the IRQ chip initialization and defines the named IRQ resources that the charger driver requires to register its handlers. Charger & USB Type-C: To avoid a regression, the charger driver needed to take over charger mode programming from the TCPC driver (where it was previously handled as a workaround). Merging these separately would have created a race condition or left the hardware in an inconsistent state during the transition. I see now that this made the patchset difficult to manage across subsystems. For future cases involving such dependencies, would you recommend providing an immutable branch for maintainers to pull from, or is there a different preferred workflow you'd suggest?
