usb: add a HCD_DMA flag instead of guestimating DMA capabilities

2019-08-21T17:03:35Z

The usb core is the only major place in the kernel that checks for a non-NULL device dma_mask to see if a device is DMA capable. This is generally a bad idea, as all major busses always set up a DMA mask, even if the device is not DMA capable - in fact bus layers like PCI can't even know if a device is DMA capable at enumeration time. This leads to lots of workaround in HCD drivers, and also prevented us from setting up a DMA mask for platform devices by default last time we tried. Replace this guess with an explicit HCD_DMA that is set by drivers that appear to have DMA support.

USB: renesas_usbhs: Remove redundant license text

2017-11-07T14:45:01Z

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/

2017-11-04T10:48:02Z

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: renesas_usbhs: constify hc_driver structures

2017-07-30T14:26:52Z

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

usb: renesas_usbhs: change arguments of dma_map_ctrl()

usb: renesas_usbhs: Modify pipe configuration

2015-12-15T15:12:41Z

The current code has info->bufnmb_last to calculate the BUFNMB bits of PIPEBUF register. However, since the bufnmb_last is initialized in the usbhs_pipe_init() only, this driver is possible to set unexpected value to the register if usb_ep_{enable,disable}() are called many times. So, this patch modifies the pipe configuration via struct renesas_usbhs_driver_param to simplify the code. Also this patch changes: - a double buffer configuration - isochronous buffer size from 512 to 1024 Signed-off-by: Yoshihiro Shimoda Signed-off-by: Felipe Balbi
