Subject: [PATCH v3 3/7] media: renesas: vsp1: Change V3U to be gen4
Date: Wed, 21 Dec 2022 11:24:44 +0200	[thread overview]
Message-ID: <20221221092448.741294-4-tomi.valkeinen+renesas@ideasonboard.com> (raw)
In-Reply-To: <20221221092448.741294-1-tomi.valkeinen+renesas@ideasonboard.com>

V3U is actually gen4, not gen3. The same IP is also used in the
(not-yet-supported) V4H.

Change VI6_IP_VERSION_MODEL_VSPD_V3U to VI6_IP_VERSION_MODEL_VSPD_GEN4,
to represent the model correctly. V3U and V4H can still be
differentiated, if needed, with the VI6_IP_VERSION_SOC_xxx.

Also mark VI6_IP_VERSION_MODEL_VSPD_GEN4 as gen 4 in vsp1_device_info,
and update the code to correctly match for gen 4.
