Subject: [PATCH v2 11/18] dmaengine: ti: k3-psil-j721e: Add entry for CSI2RX
Date: Wed, 26 May 2021 20:53:01 +0530	[thread overview]
Message-ID: <20210526152308.16525-12-p.yadav@ti.com> (raw)
In-Reply-To: <20210526152308.16525-1-p.yadav@ti.com>

The CSI2RX subsystem uses PSI-L DMA to transfer frames to memory. It can
have up to 32 threads but the current driver only supports using one. So
add an entry for that one thread.

Signed-off-by: Pratyush Yadav <p.yadav@ti.com>

Changes in v2:
- Add all 64 threads, instead of having only the one thread being
  currently used by the driver.
