Subject: [PATCH 28/28] media: ti-vpe: cal: support 8 DMA contexts
Date: Mon, 12 Apr 2021 14:34:57 +0300 [thread overview]
Message-ID: <20210412113457.328012-29-tomi.valkeinen@ideasonboard.com> (raw)
In-Reply-To: <20210412113457.328012-1-tomi.valkeinen@ideasonboard.com>
The current driver only ever needs 2 DMA contexts (one per PHY), but we
need to use more of the 8 contexts to add support for multiple streams.
Change the code so that we allocate DMA contexts as needed, which at
this time is 1 per PHY, but could be up to 8.
