[PATCH v7 09/34] dt-bindings: pinctrl: airoha: en7581: allow configuration of pcie_reset pins as gpio or pwm
From: Mikhail Kshevetskiy
Date: Mon Jul 27 2026 - 03:52:48 EST
In the an7581 case
* gpio47 and pcie_reset0 shares the same pin,
* gpio48 and pcie_reset1 shares the same pin,
* gpio49 and pcie_reset2 shares the same pin.
This patch defines a way to configure these pins as gpio or pwm.
