Subject: [PATCH] dt-bindings: usb: vialab,vl817: remove reset-gpios from required list
Date:   Wed, 18 Oct 2023 00:01:58 +0800
Message-Id: <20231017160158.1065-1-jszhang@kernel.org>

The "reset-gpios" is optional in real case, for example reset pin is
is hard wired to "high". And this fact is also reflected by the
devm_gpio_get_optional() calling in driver code.
