| 8 | |
| 9 | description: | |
| 10 | The TI J721E CSI2RX Shim is a wrapper around Cadence CSI2RX bridge that |
| 11 | enables sending captured frames to memory over PSI-L DMA. In the J721E |
| 12 | Technical Reference Manual (SPRUIL1B) it is referred to as "SHIM" under the |
| 13 | CSI_RX_IF section. |
