Subject: [PATCH v2 8/9] media: v4l: uapi: Add user control base for stm32 dma2d controls
Date: Thu, 15 Jul 2021 17:24:27 +0800	[thread overview]
Message-ID: <1626341068-20253-19-git-send-email-dillon.minfei@gmail.com> (raw)
In-Reply-To: <1626341068-20253-1-git-send-email-dillon.minfei@gmail.com>

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

Add a control base for stm32 controls, and reserve 16 controls.

Signed-off-by: Dillon Min <dillon.minfei@gmail.com>
