Subject: [PATCH 08/17] media: camss: csid-170: set the right HALT_CMD when disabled
Date: Tue,  8 Jun 2021 18:34:57 -0400	[thread overview]
Message-ID: <20210608223513.23193-9-jonathan@marek.ca> (raw)
In-Reply-To: <20210608223513.23193-1-jonathan@marek.ca>

Use the "HALT_CMD_RESUME_AT_FRAME_BOUNDARY" define instead of a "1" which
is otherwise confusing, and add a "HALT_CMD_HALT_AT_FRAME_BOUNDARY" which
is set when disabling.

Fixes: eebe6d00e9bf ("media: camss: Add support for CSID hardware version Titan 170")
Signed-off-by: Jonathan Marek <jonathan@marek.ca>
