usb: dwc2: Rename hibernation to partial_power_down

2018-03-13T08:47:53+00:00

No-op change, only rename. This code was misnamed originally. It was only responsible for partial power down and not for hibernation. Rename core_params->hibernation to core_params->power_down, dwc2_set_param_hibernation() to dwc2_set_param_power_down().

usb: dwc2: Add core parameters for LPM support

2018-03-13T08:47:47+00:00

Add lpm, lpm_clock_gating, besl, hird_threshold_en and hird_threshold core parameters. These will indicate LPM and LPM Errata support as well as chosen L1 sleeping mode for the core and PHY. Signed-off-by: Sevak Arakelyan Signed-off-by: Grigor Tovmasyan Signed-off-by: Felipe Balbi

USB: dwc2: Re-use DEFINE_SHOW_ATTRIBUTE() macro

2018-03-08T13:12:00+00:00

...instead of open coding file operations followed by custom ->open() callbacks per each attribute. Cc: John Youn Signed-off-by: Andy Shevchenko Signed-off-by: Felipe Balbi

USB: dwc2: Remove redundant license text

2017-11-07T14:45:01+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: dwc2: Cleanup some checkpatch issues

2017-01-24T09:04:18+00:00

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: Use platform endianness when accessing registers

2015-09-27T15:54:31+00:00

This patch switches calls to readl/writel to their dwc2_readl/dwc2_writel equivalents which preserve platform endianness. This patch is necessary to access dwc2 registers correctly on big-endian systems such as the mips based SoCs made by Lantiq. Then dwc2 can be used to replace ifx-hcd driver for Lantiq platforms found e.g. in OpenWrt. The patch was autogenerated with the following commands: $EDITOR core.h sed -i "s/\/dwc2_readl/g" *.c hcd.h hw.h sed -i "s/\/dwc2_writel/g" *.c hcd.h hw.h Some files were then hand-edited to fix checkpatch.pl warnings about too long lines.
