Subject: [PATCH v3 3/3] dt-bindings: pinctrl: mediatek,mt8365-pinctrl: add drive strength property
Date: Tue, 04 Apr 2023 18:29:51 +0200	[thread overview]
Message-ID: <20230327-cleanup-pinctrl-binding-v3-3-6f56d5c7a8de@baylibre.com> (raw)
In-Reply-To: <20230327-cleanup-pinctrl-binding-v3-0-6f56d5c7a8de@baylibre.com>

This SoC is able to drive the following output current:
- 2 mA
- 4 mA
- 6 mA
- 8 mA
- 10 mA
- 12 mA
- 14 mA
- 16 mA

Then drive-strength property is set with enum to reflect its HW capability.
