[PATCH] mmc: renesas_sdhi: add regulator dependency

From: Arnd Bergmann
Date: Sat Mar 29 2025 - 04:21:36 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

The driver started using the regulator subsystem and fails to build without
that now:

ERROR: modpost: "rdev_get_drvdata" [drivers/mmc/host/renesas_sdhi_core.ko] undefined!
ERROR: modpost: "devm_regulator_register" [drivers/mmc/host/renesas_sdhi_core.ko] undefined!

Add a Kconfig dependency for this.

The 'select RESET_CONTROLLER' needs to either go away or get changed to a dependency
in order to avoid Kconfig dependency loops here. The 'select' is otherwise used by
drivers that register a reset controller, but normally not by those that just use one.

Fixes: fae80a99dc03 ("mmc: renesas_sdhi: Add support for RZ/G3E SoC")
