Subject: [PATCH] dt-bindings: pinctrl: mt8192: Add mediatek, pull-down-adv property
Date: Fri, 29 Apr 2022 16:06:37 -0400 [thread overview]
Message-ID: <20220429200637.2204937-1-nfraprado@collabora.com> (raw)
Add the mediatek,pull-down-adv property to the pinctrl-mt8192 dt-binding
to allow configuring pull-down resistors on the pins of MT8192. It is
the same as in mt8183-pinctrl.
