Subject: [PATCH v2 1/6] dt-bindings: media: rockchip,rk3568-vepu: Add the reset lines
Date: Thu, 12 Nov 2026 08:30:47 +0000 [thread overview]
Message-ID: <20261112-hantro-robust-v2-1-18561fd48838@gmail.com> (raw)
In-Reply-To: <20261112-hantro-robust-v2-0-18561fd48838@gmail.com>
From: Arun Iyengar <aiyengar1990@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.
