Subject: [PATCH v4 6/8] media: v4l2-ctrls: Add RGB color effects control
Date: Thu, 14 Oct 2021 18:25:04 +0800	[thread overview]
Message-ID: <1634207106-7632-7-git-send-email-dillon.minfei@gmail.com> (raw)
In-Reply-To: <1634207106-7632-1-git-send-email-dillon.minfei@gmail.com>

From: Dillon Min <dillon.minfei@gmail.com>

Add V4L2_COLORFX_SET_RGB color effects control, V4L2_CID_COLORFX_RGB
for RGB color setting.

Signed-off-by: Dillon Min <dillon.minfei@gmail.com>
---
v4:
- replace V4L2_COLORFX_SET_ARGB, V4L2_CID_COLORFX_ARGB to
  V4L2_COLORFX_SET_RGB, V4L2_CID_COLORFX_RGB since Alpha paramter not used
  in current. thanks Hans.
