Subject: [PATCH v2 2/3] usb: typec: ucsi: Report power supply changes on power opmode changes
Date: Thu, 16 Oct 2025 23:59:08 +0000 [thread overview]
Message-ID: <20251016235909.2092917-3-jthies@google.com> (raw)
In-Reply-To: <20251016235909.2092917-1-jthies@google.com>
Report opmode changes from the PPM to the power supply class by calling
ucsi_port_psy_changed(). If the current opmode is USB PD, do not call
ucsi_port_psy_changed(). The power supply class will be updated after
requesting partner source PDOs.
