2020-04-16USB: host: Use the correct style for SPDX License IdentifierNishad Kamdar
This patch corrects the SPDX License Identifier style in header files related to USB host controller drivers. For C header files Documentation/process/license-rules.rst mandates C-like comments (opposed to C source files where C++ style should be used). Changes made by using a script provided by Joe Perches here: https://lkml.org/lkml/2019/2/7/46.

2017-11-07USB: host: Remove redundant license textGreg Kroah-Hartman
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.

2017-11-04USB: add SPDX identifiers to all remaining files in drivers/usb/Greg Kroah-Hartman
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.

2017-11-01usb: r8a66597-hcd: Convert timers to use timer_setup()Kees Cook
In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly. This rearranges the arrays of timers to minimize the need for a pointer back to the main structure.

2011-07-08usb: r8a66597-hcd: add function for external controllerYoshihiro Shimoda
R8A66597 has the pin of WR0 and WR1. So, if one write-pin of CPU connects to the pins, we have to change the setting of FIFOSEL register in the controller. If we don't change the setting, the controller cannot send the data of odd length.

2010-06-02usb: r8a66597-hcd pio to mmio accessor conversion.Paul Mundt
r8a66597-hcd is erroneously using PIO routines on MMIO registers, which presently blows up for any platform that elects to either override or do away with PIO routines. This managed to work for the common cases since the PIO routines were simply wrapped to their MMIO counterparts. This switches over to using the MMIO routines directly, and enables us to kill off a lot of superfluous casting in the process.

2009-07-23usb: move r8a66597 register definesMagnus Damm
Move r8a66597 hardware register definitions from the host controller header file to the platform data header file. With this change in place we can easily share register definitions between the host controller driver and a future gadget driver.

2009-07-20usb: r8a66597-hcd platform data on_chip supportMagnus Damm
Convert the r8a66597-hcd driver to use the on_chip flag from platform data to enable on chip behaviour instead of relying on CONFIG_SUPERH_ON_CHIP_R8A66597 ugliness. This makes the code cleaner and also allows us to support both external and internal r8a66597 with the same kernel. It also makes the Kconfig part more future proof since we with this patch can add support for new processors with on-chip r8a66597 without modifying the Kconfig.

2007-07-12USB: r8a66597-hcd: host controller driver for R8A66597Yoshihiro Shimoda
I would like to submit Renesas R8A66597 USB HCD driver. R8A66597 is Renesas USB 2.0 host and peripheral combined controller device originally designed for embedded products. As a limitation of this device, it does not support externel hub more than 2 tier, and cannot communicate with a USB device more than 10. Then this device is not compatible with EHCI and/or OHCI, I wrote driver support patch based on sl811 code. This driver has the following unique specifications: - Implement transfer timeout to share one pipe with plural endpoint. - Detach detection of a USB device connected to externel hub. The driver has been tested external hub, usb-hdd, usb-cdrom, usb-speaker, mice, keyboard, and usbtest driver.
