usb: dwc2: Remove redundant license text

2022-09-22T13:52:29Z

SPDX-License-Identifier have been added in commit 5fd54ace4721 ("USB: add SPDX identifiers to all remaining files in drivers/usb/") There is no point in keeping the now redundant license text. Remove it.

usb: dwc2: Modify dwc2_readl/writel functions prototype

2018-07-30T07:39:16Z

Added hsotg argument to dwc2_readl/writel function prototype, and also instead of address pass offset of register. hsotg will contain flag field for endianness. Also customized dwc2_set_bit and dwc2_clear_bit function for dwc2_readl/writel functions. Signed-off-by: Gevorg Sahakyan Signed-off-by: Felipe Balbi

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: dwc2: Cleanup some checkpatch issues

2017-01-24T09:04:18Z

This commmit is the result of running checkpatch --fix. The results were verified for correctness. Some of the fixes result in line over 80 char which we will fix manually later. The following is a summary of what was done by checkpatch: * Remove externs on function prototypes. * Replace symbolic permissions with octal. * Align code to open parens. * Replace 'unsigned' with 'unsigned int'. * Remove unneccessary blank lines. * Add blank lines after declarations. * Add spaces around operators. * Remove unnecessary spaces after casts. * Replace 'x == NULL' with '!x'. * Replace kzalloc() with kcalloc(). * Concatenate multi-line strings. * Use the BIT() macro.

usb: dwc2: host: Rename MAX_DMA_DESC_SIZE to HOST_DMA_NBYTES_LIMIT

2016-11-18T11:54:19Z

Rename MAX_DMA_DESC_SIZE to HOST_DMA_NBYTES_LIMIT as it stores value of host DMA descriptor transfer bytes' limit. Values are different in case of gadget DMA descriptors. Signed-off-by: Vahram Aharonyan Signed-off-by: John Youn Signed-off-by: Felipe Balbi
