Subject: [PATCH v5 5/8] media: staging: tegra-vde: Bump BSEV DMA timeout
Date: Sun, 20 Feb 2022 23:46:20 +0300 [thread overview]
Message-ID: <20220220204623.30107-6-digetx@gmail.com> (raw)
In-Reply-To: <20220220204623.30107-1-digetx@gmail.com>
BSEV DMA timeouts if VDE is downclocked by x10. Bump the timeout to allow
DMA to complete. We don't support freq scaling yet, this is just a minor
improvement which may become useful sometime later.
