-Subject: [PATCH] usb: dwc2: masquerade split-interrupt transfers
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Masquerading Interrupt split transfers as Control puts the transfer into
-the non-periodic handler in the hub. This stops the hub dropping
-complete-split data in the microframe after a CSPLIT should have
-arrived, improving resilience to host IRQ latency. Devices are none
-the wiser - the handshake tokens are the same.
-
-Originally devised by Hans Petter Selasky @ FreeBSD.
-
-(v2: dwc2 needs an un-masquerade prior to channel interrupt handling)
-
-Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com>
-(cherry picked from commit 5329a41ef5655b559fb5274123ce13a0287db878)
