[PATCH 1/5] dt-bindings: media: rockchip,rk3568-vepu: Add the reset lines

From: Arun Iyengar <aiyengar1990 at gmail.com>

The VEPU121 encoder cores of the RK3588 each have their own AXI and AHB
reset lines in the CRU (SRST_A_JPEG_ENCODERx and SRST_H_JPEG_ENCODERx).
They are needed to recover a core that is stuck on the bus, which its
registers can't stop.

Describe them as optional, so that existing device trees stay valid.
