Subject: [PATCH v1 0/2] To support the HFP WBS, a chip vendor may choose a particular
Date: Thu, 13 Aug 2020 16:41:27 +0800	[thread overview]
Message-ID: <20200813084129.332730-1-josephsih@chromium.org> (raw)

USB alternate seeting of which the packet size is distinct.
The patches are to expose the packet size to user space so that
the user space does not need to hard code those values.

We have verified this patch on Chromebooks which use
- Realtek 8822CE controller with USB alt setting 1
- Intel controller with USB alt setting 6
Our user space audio server, cras, can get the correct
packet length from the socket option.
