Subject: [PATCH v2] dt-bindings: pinctrl: mt8186: Fix 'reg-names' for pinctrl nodes
Date:   Wed, 17 Aug 2022 13:26:15 +0800
Message-ID: <20220817052615.27153-1-allen-kh.cheng@mediatek.com>
MIME-Version: 1.0
Content-Type: text/plain
Precedence: bulk

The mt8186 contains 8 GPIO physical address bases that correspond to
the 'reg-names' of the pinctrl driver. The 'reg-names' entries in
bindings are ordered incorrectly, though. The system crashes due of an
erroneous address when the regulator initializes.

We fix the 'reg-names' for the pinctrl nodes and the pinctrl-mt8186
example in bindings.

Fixes: 338e953f1bd1 ("dt-bindings: pinctrl: mt8186: add pinctrl file and binding document")
