Subject: [PATCH v2 2/5] dt-bindings: media: IMX8MQ VPU: document reset usage
Date: Fri, 26 Feb 2021 10:11:25 +0100 [thread overview]
Message-ID: <20210226091128.14379-3-benjamin.gaignard@collabora.com> (raw)
In-Reply-To: <20210226091128.14379-1-benjamin.gaignard@collabora.com>
Document IMX8MQ VPU bindings to add the phandle to the reset driver.
Provide an independent reset driver allow to the both VPUs to share
their control/reset hardware block. The reset driver replace what
was previously done be using the 'ctrl' registers inside the driver.
This breaks the compatibility between DTB and kernel but the driver
is still in staging directory and limited to IMX8MQ SoC.
