Subject: [PATCH RFC 1/3] dt-bindings: crypto: Add binding for TI DTHE V2 driver

Add new DT binding for Texas Instruments DTHE V2 crypto driver.

DTHE V2 is introduced as a part of TI AM62L SoC and can currently be
only found in it.

Signed-off-by: T Pratham <t-pratham@...com>

PS: Please note that the dmas option in dt-bindings is subject to change in
future as dma driver is not finalized yet. Any updated changes will be
sent in the next version of the patch.
