Unfortunately (?) "Audio DMAC Peripheral Peripheral"
(= double Peripheral) is the formal name

Oops, this is my fault.
I will fix in v2

Hmm...
This driver is called from shdma-base.c.
And shdmac.c/sudmac.c/rcar-hpbdmac.c are same style.
1) this "slave_id" came from shdma_ops::set_slave
and, it is using "int"
2) above drivers have same xxx_find_slave(),
they are using "int".
(this driver is based on that)
What should I do ?

I will fixup these in v2
Thank you
Best regards
