Dear Maintainer,

For RZ platform the DMA engine needs enabling using the kernel config:

CONFIG_RZ_DMAC=m

Please support to enable this config in debian kernel config:

https://salsa.debian.org/kernel-team/linux/-/blob/debian/latest/debian/config/arm64/config

-- System Information:

Debian Release: Trixie 
Architecture: arm64 
Kernel: Linux 6.18.rc5

This is the second bug you've opened requesting a single driver for the
RZ platform.  Can you provide a list of *all* the drivers that should be
enabled?  From a quick look through the Kconfig files it seems like we
are also missing RTC, watchdog, PWM, reset, DRM, and other drivers.

Ben.
