Subject: [PATCH v2 07/13] gpu: host1x: Allow reset to be missing
Date: Wed, 22 Jun 2022 14:37:27 +0300 [thread overview]
Message-ID: <20220622113733.1710471-8-cyndis@kapsi.fi> (raw)
In-Reply-To: <20220622113733.1710471-1-cyndis@kapsi.fi>
From: Mikko Perttunen <mperttunen@nvidia.com>
Host1x on Tegra234 does not have a software-controllable reset line.
As such, don't bail out if we don't find one in the device tree.
