Subject: [PATCH v7/v3 16/22] gpu: host1x: Allow reset to be missing
Date: Mon, 27 Jun 2022 17:20:02 +0300	[thread overview]
Message-ID: <20220627142008.2072474-17-cyndis@kapsi.fi> (raw)
In-Reply-To: <20220627142008.2072474-1-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.
