Subject: [PATCH v2 0/8] usb: Check for genXxY on host
Date: Wed, 03 Feb 2021 20:10:25 -0800 [thread overview]
Message-ID: <cover.1612410491.git.Thinh.Nguyen@synopsys.com> (raw)
This series add some missing support for USB 3.2 SuperSpeed Plus detection on
the host side. A SuperSpeed Plus device can operate in gen2x2, gen2x1, or
gen1x2. The current implementation can't detect whether the device is in Gen 1
or Gen 2 speed. We can do this by matching for the lane speed exponent and
mantissa of the SSP sublink speed capability descriptor from the hub driver.
Also, the current xHCI driver is missing some reports for the default SSP
Sublink Speed capability for USB 3.2 roothub. This series also add some support
for xHCI driver detecting various SuperSpeed Plus GenXxY.
Changes in v2:
- Remove RFC tag
- Rebase on greg/usb-testing
- Make some updates on BOS descriptor creation base on Mathias suggestions
Thinh Nguyen (8):
usb: core: Track SuperSpeed Plus GenXxY
usb: core: hub: Remove port_speed_is_ssp()
usb: core: hub: Print speed name based on ssp rate
usb: core: sysfs: Check for SSP rate in speed attr
usb: xhci: Init root hub SSP rate
usb: xhci: Fix port minor revision
usb: xhci: Rewrite xhci_create_usb3_bos_desc()
usb: xhci: Remove unused function
