Subject: [RFC PATCH 4/7] usb: typec: ucsi: acpi: Reduce the command completion timeout
Date: Thu, 26 Aug 2021 17:31:43 +0300 [thread overview]
Message-ID: <20210826143146.25799-5-heikki.krogerus@linux.intel.com> (raw)
In-Reply-To: <20210826143146.25799-1-heikki.krogerus@linux.intel.com>
The huge delay was there to workaround a problem where the
firmware did not report that it was busy with the alternate
mode commands. Now that the alternate modes are polled, the
delay can be dropped.
