Subject: [RFC PATCH V3 5/5] media: platform: mtk-mdp3: Add struct tuning_addr and img_sw_buffer

From: <[email-masked]>
Date: Tue, 10 Sep 2019 03:22:44 +0800

From: Frederic Chen <[email-masked]>

We added a struct tuning_addr which contains a field "present"
so that the driver can tell the firmware if we have user tuning
dataor not.

The strcut img_sw_buffer is also added. This struct has no cpu address
field and uses a handle instead so that we don't pass a cpu address
to co-processor.
