Subject: [PATCH] media: rkisp1: Adapt to different SoCs having different size limits
Date: Wed, 21 Feb 2024 00:57:17 +0100
Message-ID: <20240220235720.3010608-1-megi@xff.cz>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

From: Ondrej Jirman <megi@xff.cz>

- RK3399 has input/output limit of main path 4416 x 3312
- PX30 has input/output limit of main path 3264 x 2448

Use rkisp1_info struct to encode the limits.
