linux-toradex.git/include/linux/phy/phy-sun4i-usb.h, branch v4.4.93 Linux kernel for Apalis and Colibri modules phy: sun4i-usb: Add a sunxi specific function for setting squelch-detect 2015-05-27T17:20:36+00:00 Hans de Goede hdegoede@redhat.com 2015-03-29T10:50:46+00:00 24fe86a617c550fb9bdc6c8bd7cf647d3955f8ba The sunxi otg phy has a bug where it wrongly detects a high speed squelch when reset on the root port gets de-asserted with a lo-speed device. The workaround for this is to disable squelch detect before de-asserting reset, and re-enabling it after the reset de-assert is done. Add a sunxi specific phy function to allow the sunxi-musb glue to do this.

The sunxi otg phy has a bug where it wrongly detects a high speed squelch
when reset on the root port gets de-asserted with a lo-speed device.

The workaround for this is to disable squelch detect before de-asserting
reset, and re-enabling it after the reset de-assert is done. Add a sunxi
specific phy function to allow the sunxi-musb glue to do this.
