Subject: [PATCH v1] drm/panthor: skip regulator setup if no such prop
Date: Fri, 26 Sep 2025 17:07:22 +0800	[thread overview]
Message-ID: <20250926090722.23097-1-jiyu.yang@oss.nxp.com> (raw)

From: Rain Yang <jiyu.yang@nxp.com>

The regulator is optional, skip the setup instead of returning an
error if it is not present
