USB: add SPDX identifiers to all remaining Makefiles

2017-11-07T14:53:48+00:00

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. This updates the remaining drivers/usb/*Makefile* that were missing SPDX identifiers. They all get the following identifier: SPDX-License-Identifier: GPL-2.0 The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text.

USB: c67x00: 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: c67x00: remove redundant pointer urbp

2017-11-01T16:05:17+00:00

Pointer urbp is assigned but is never read, hence it is redundant and can be removed. Cleans up clang warning: drivers/usb/c67x00/c67x00-sched.c:975:2: warning: Value stored to 'urbp' is never read Signed-off-by: Colin Ian King Signed-off-by: Greg Kroah-Hartman

c67x00-hcd: constify hc_driver structures

2017-07-30T14:26:52+00:00

The hc_driver structure is only passed as the first argument to usb_create_hcd, which is declared as const. Thus the hc_driver structure itself can be const. Done with the help of Coccinelle. Signed-off-by: Julia Lawall Signed-off-by: Greg Kroah-Hartman

c67x00-hcd: use USB_DT_HUB

usb: c67x00: drop owner assignment from platform_drivers

2014-10-20T14:21:46+00:00

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

USB: c67x00: add proper delays to HPI read/write

2014-01-08T00:15:39+00:00

According to CY7C67300 specification HPI read and write cycle duration Tcyc must be at least 6T long, where T is 1/48MHz, which is 125ns. Without this delay fast host processor cannot write to chip registers. Add proper ndelay to hpi_{read,write}_reg.
