SubjectRe: [PATCH v2 0/2] Add memcpy support for tegra210-adma

Thanks. Any reason you choose this DMA and not the APB DMA? The APB DMA
is more of a generic DMA and so for memcpy it would seem to be a good
choice and it is available on all Tegras not just Tegra210.

Furthermore, from a power standpoint the ADMA is in the audio power
domain and so using it for memcpy would mean the audio power domain is
turned on. It may not be a big deal for some, but given the APB is in
the CORE domain (always on when not in low-power) it seems like a better
choice for power as well.

Cheers
Jon
