Subject: [PATCH 1/5] dt-bindings: serial: 8250_omap: Add wakeup pinctrl state
Date: Thu, 23 May 2024 09:58:15 +0200

Pins associated with the 8250 omap unit can be the source of a wakeup in
deep sleep states. To be able to wakeup, these pins have to be
configured in a special way. To support this configuration add the
default and wakeup pinctrl states.
