usb: isp1760: use the right irq status bit

2021-08-27T14:11:39Z

Instead of using the fields enum values to check interrupts trigged, use the correct bit values. Reported-by: Dietmar Eggemann Tested-by: Dietmar Eggemann Signed-off-by: Rui Miguel Silva Link: https://lore.kernel.org/r/20210827131154.4151862-5-rui.silva@linaro.org Signed-off-by: Greg Kroah-Hartman

usb: isp1760: isp1760-udc: Provide missing description for 'udc' param

2021-05-27T07:45:27Z

Fixes the following W=1 kernel build warning(s): drivers/usb/isp1760/isp1760-udc.c:150: warning: Function parameter or member 'udc' not described in 'isp1760_udc_select_ep' Cc: Greg Kroah-Hartman Cc: Rui Miguel Silva Cc: Laurent Pinchart Cc: linux-usb@vger.kernel.org Reviewed-by: Rui Miguel Silva Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/20210526130037.856068-7-lee.jones@linaro.org Signed-off-by: Greg Kroah-Hartman

usb: isp1763: add peripheral mode

2021-05-21T18:05:32Z

Besides the already host mode support add peripheral mode support for the isp1763 IP from the isp1760 family. Signed-off-by: Rui Miguel Silva Link: https://lore.kernel.org/r/20210513084717.2487366-10-rui.silva@linaro.org Signed-off-by: Greg Kroah-Hartman

usb: isp1760: add support for isp1763

2021-05-21T18:05:32Z

isp1763 have some differences from the isp1760, 8 bit address for registers and 16 bit for values, no bulk access to memory addresses, 16 PTD's instead of 32. Following the regmap work done before add the registers, memory access and add the functions to support differences in setup sequences.

usb: isp1760: move to regmap for register access

2021-05-21T18:05:31Z

Rework access to registers and memory to use regmap framework. No change in current feature or way of work is intended with this change. This will allow to reuse this driver with other IP of this family, for example isp1763, with little changes and effort.

usb: isp1760: Use kasprintf

2018-03-09T17:40:21Z

Use kasprintf instead of combination of kmalloc and sprintf and therefore avoid unnecessary computation of string length. Also, remove the useless local variable. Signed-off-by: Himanshu Jha Reviewed-by: Kees Cook Signed-off-by: Greg Kroah-Hartman

USB: isp1760: 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: isp1760: Convert timers to use timer_setup()

2017-11-01T15:57:23Z

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. Cc: "Gustavo A. R. Silva" Cc: Bhumika Goyal Signed-off-by: Kees Cook Signed-off-by: Greg Kroah-Hartman

usb: isp1760: constify usb_gadget_ops structures

2017-01-19T09:34:45Z

Declare usb_gadget_ops structures as const as they are only stored in the ops field of a usb_gadget structure. This field is of type const, so usb_gadget_ops structures having this property can be declared const too.
