Subject: [PATCH 0/3] usb: gadget: uvc: allocate requests based on frame interval length and buffersize
Date: Tue, 09 Apr 2024 23:24:56 +0200 [thread overview]
Message-ID: <20240403-uvc_request_length_by_interval-v1-0-9436c4716233@pengutronix.de> (raw)
This patch series is improving the size calculation and allocation
of the uvc requests. Using the currenlty setup frame duration of the
stream it is possible to calculate the number of requests based on the
interval length.
