[PATCH 09/11] regulator: db8500-prcmu: Remove EPOD regulators
Linus Walleij
linusw at kernel.org
Wed Jun 17 22:00:55 PDT 2026
Remove the obsolete DB8500 PRCMU regulator drivers.
Drop the regulator build hooks now that EPODs are power domains.
Keep the MFD cell around because a later patch reuses it for a
small compatibility regulator driver.
