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 <redacted> --- Changes in v2: - Add all 64 threads, instead of having only the one thread being currently used by the driver.
How many threads CSI2RX have? 32 (as per commit message) or 64? If I recall right, it is 32.
