Subject: [PATCH v2 3/9] media: hantro: Add a field to distinguish the hardware versions
Date: Thu, 18 Feb 2021 20:18:38 +0100 [thread overview]
Message-ID: <20210218191844.297869-4-benjamin.gaignard@collabora.com> (raw)
In-Reply-To: <20210218191844.297869-1-benjamin.gaignard@collabora.com>
Decoders hardware blocks could exist in multiple versions: add
a field to distinguish them at runtime.
G2 hardware block doesn't have postprocessor hantro_needs_postproc
function should always returns false in for this hardware.
hantro_needs_postproc function becoming to much complex to
stay inline in .h file move it to .c file.
Keep the default behavoir to be G1 hardware.

version 2:
- squash this commit with the post processor change
to show one usage of core_hw_dec_rev
