Subject: [PATCH v2 0/3] dmaengine: Add support for immediate commands
Date: Thu, 27 Oct 2022 10:44:26 +0530	[thread overview]
Message-ID: <20221027051429.46593-1-sireeshkodali1@gmail.com> (raw)

The IPA v2.x block, found on some older Qualcomm SoCs, uses BAM DMA to
send and receive packets from the AP. It also uses BAM to receive
commands from the AP (and possibly the modem). These commands are
encoded as "Immediate Commands". They vary from regular BAM DMA
commands. Adding support for immediate commands is trivial, but requires
also adding Immediate Commands to the dmaengine API, which is what this
patch series does.
