Subject: [PATCH 0/4] Reset driver for IMX8MQ VPU hardware block
Date: Thu, 11 Feb 2021 12:49:59 +0100 [thread overview]
Message-ID: <20210211115003.249367-1-benjamin.gaignard@collabora.com> (raw)
The two VPUs inside IMX8MQ share the same control block which can be see
as a reset hardware block.
In order to be able to add the second VPU (for HECV decoding) it will be
more handy if the both VPU drivers instance don't have to share the
control block registers. This lead to implement it as an independ reset
driver and to change the VPU driver to use it.
