Subject: [PATCH 14/18] media: hantro: make PP enablement logic a bit smarter
Date: Mon, 12 Oct 2020 23:59:53 +0300
Message-ID: <20201012205957.889185-15-adrian.ratiu@collabora.com> (raw)
In-Reply-To: <20201012205957.889185-1-adrian.ratiu@collabora.com>

Now that we support two cores with different PP operations we need
to make the condition to enable PP a bit smarter based on what is
actually supported by each core.

While doing this also move the needs_postproc() test inside the
postproc .c file instead of cluttering the header.
