Subject: media: rkisp1: Add features mask to extensible block handlers
Author: Laurent Pinchart <laurent.pinch...@ideasonboard.com>
Date: Thu Aug 8 22:41:02 2024 +0200
Future ISP parameter blocks for i.MX8MP-specific features will not
support on Rockchip platforms as they lack the corresponding hardware.
Introduce a features mask in the extensible block handlers to indicate
which device features a block require, and ignore blocks that require
unavailable features.
