Subject: [PATCH v1 3/4] usb: typec: ucsi: Delay alternate mode discovery
Date: Fri, 19 Apr 2024 21:16:49 +0000 [thread overview]
Message-ID: <20240419211650.2657096-4-jthies@google.com> (raw)
In-Reply-To: <20240419211650.2657096-1-jthies@google.com>
Delay the ucsi_check_altmodes task to be inline with surrounding partner
tasks. This allows partner, cable and identity discovery to complete
before alternate mode registration. With that order, alternate mode
discovery can be used to indicate the ucsi driver has completed
discovery.
