Subject: [PATCH 1/2] dt-bindings: pinctrl: mediatek: deprecate custom drive strength property
Date: Tue, 28 Mar 2023 15:06:32 +0200	[thread overview]
Message-ID: <20230327-cleanup-pinctrl-binding-v1-1-b695e32e4f2e@baylibre.com> (raw)
In-Reply-To: <20230327-cleanup-pinctrl-binding-v1-0-b695e32e4f2e@baylibre.com>

Deprecate mediatek,drive-strength-adv which shall not exist, that was an
unnecessary property that leaked upstream from downstream kernels and
there's no reason to use it.

The generic property drive-strength-microamp should be used instead.
