Subject: [PATCH 2/7] dt-bindings: can: m_can: Add wakeup pinctrl state
Date: Thu, 23 May 2024 09:53:42 +0200	[thread overview]
Message-ID: <20240523075347.1282395-3-msp@baylibre.com> (raw)
In-Reply-To: <20240523075347.1282395-1-msp@baylibre.com>

Pins associated with m_can 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.
