USB: fhci-hcd: no need to check return value of debugfs_create functions

2018-05-31T10:54:22+00:00

When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

There is also no need to keep the file dentries around at all, so remove
those variables from the host controller structure.

USB: host: fhci: Re-use DEFINE_SHOW_ATTRIBUTE() macro

2018-03-09T17:31:25+00:00

...instead of open coding file operations followed by custom ->open()
callbacks per each attribute.

USB: host: fhci: Remove redundant license text

2017-11-07T14:45:02+00:00

Now that the SPDX tag is in all USB files, that identifies the license
in a specific and legally-defined manner.  So the extra GPL text wording
can be removed as it is no longer needed at all.

This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text.  And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.

No copyright headers or other non-license-description text was removed.

USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02+00:00

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Update the drivers/usb/ and include/linux/usb* files with the correct
SPDX license identifier based on the license text in the file itself.
The SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.

This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

USB: FHCI: Reusing QUICC Engine USB Controller registers from immap_qe.h

2012-06-27T02:42:11+00:00

The struct fhci_regs (in drivers/usb/host/fhci.h) is basically a redefinition
of the struct qe_usb_ctlr (in arch/powerpc/include/asm/immap_qe.h).

The qe_usb_ctlr struct is preferrable once it uses accurately the registers'
names found in the Freescale's QUICC Engine Block Reference Manuals (QEIWRM.pdf
Rev.4.4 Chapter 19 for MPC836xE series and MPC8323ERM.pdf Rev.2 Chapter 36 for
MPC832xE series), making easier to map the FHCI device driver to the hardware
manual. Also, as the FHCI driver uses the USB Controller registers, the name
qe_usb_ctlr is a more precise representation of the hardware than fhci_regs.

USB: make hcd.h public (drivers dependency)

2010-05-20T20:21:30+00:00

The usbcore headers: hcd.h and hub.h are shared between usbcore,
HCDs and a couple of other drivers (e.g. USBIP modules).
So, it makes sense to move them into a more public location and
to cleanup dependency of those modules on kernel internal headers.
This patch moves hcd.h from drivers/usb/core into include/linux/usb/

USB: Driver for Freescale QUICC Engine USB Host Controller

2009-01-28T00:15:38+00:00

This patch adds support for the FHCI USB controller, as found
in the Freescale MPC836x and MPC832x processors. It can support
Full or Low speed modes.

Quite a lot the hardware is doing by itself (SOF generation, CRC
generation and checking), though scheduling and retransmission is on
software's shoulders.

This controller does not integrate the root hub, so this driver also
fakes one-port hub. External hub is required to support more than
one device.
