From 4fb48fc52cde53f93270822d381b6ae7b1427f34 Mon Sep 17 00:00:00 2001 From: Paul Elder Date: Thu, 4 Jul 2024 19:20:32 +0300 Subject: include: rkisp1: Update header for compand parameters Update the rkisp1-config.h header with the definitions for the companding block, which use the extensible parameters format. The changes come from the "[PATCH v2 0/5] media: rkisp1: Add support for the companding block" series posted to the linux-media mailing list and available at [1].
