include: fsl_devices.h: drop unused, misspelled FLS_USB2_WORKAROUND_ENGCM09152

2025-06-19T10:29:17+00:00

The macro was introduced in commit 69cb1ec4ce4d ("mxc_udc: add workaround for ENGcm09152 for i.MX35") on 2010-10-15, but its prefix was misspelled as **FLS_** instead of the usual **FSL_**. Its last in-tree user disappeared with commit a390bef7db1f ("usb: gadget: fsl_mxc_udc: Remove the driver") on 2020-12-10, so the macro has been completely unused since then. Remove the dead and wrongly named definition. Signed-off-by: RubenKelevra Link: https://lore.kernel.org/r/20250618164743.1916838-1-rubenkelevra@gmail.com Signed-off-by: Greg Kroah-Hartman

drivers: usb :fsl: Remove USB Errata checking code

2019-01-18T09:02:09+00:00

Remove USB errata checking code from driver. Applicability of erratum is retrieved by reading corresponding property in device tree. This property is written during device tree fixup. Besides, replace spaces with tabs to make code aligned.

fsl/usb: Workarourd for USB erratum-A005697

2016-12-05T14:13:58+00:00

The EHCI specification states the following in the SUSP bit description: In the Suspend state, the port is sensitive to resume detection. Note that the bit status does not change until the port is suspended and that there may be a delay in suspending a port if there is a transaction currently in progress on the USB. However, in NXP USBDR controller, the PORTSCx[SUSP] bit changes immediately when the application sets it and not when the port is actually suspended. So the application must wait for at least 10 milliseconds after a port indicates that it is suspended, to make sure this port has entered suspended state before initiating this port resume using the Force Port Resume bit. This bit is for NXP controller, not EHCI compatible. Signed-off-by: Changming Huang Signed-off-by: Ramneek Mehresh Acked-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

Incoming packets in high speed are randomly corrupted by h/w resulting in multiple errors. This workaround makes FS as default mode in all affected socs by disabling HS chirp signalling.This errata does not affect FS and LS mode.
