Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.By default all files without license information are under the default
license of the kernel, which is GPL version 2.Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if

Pull clk updates from Stephen Boyd:
"The diff is dominated by the Allwinner A10/A20 SoCs getting converted
to the sunxi-ng framework. Otherwise, the heavy hitters are various
drivers for SoCs like AT91, Amlogic, Renesas, and Rockchip. There are
some other new clk drivers in here too but overall this is just a
bunch of clk drivers for various different pieces of hardware and a
collection of non-critical fixes for clk drivers.New Drivers:
- Allwinner R40 SoCs
- Renesas R-Car Gen3 USB 2.0 clock selector PHY
- Atmel AT91 audio PLL

Since gclk (generated-clk) is now able to determine the rate of the
audio_pll, there is no need for classd to have a direct phandle to the
audio_pll while already having a phandle to gclk.Thus, remove all mentions to aclk in classd driver and update macros and
variable names.Signed-off-by: Quentin Schulz

The function platform_set_drvdata copies the value the variable
card to card->dev->driver_data, then the address of &pdev->dev is
assigned to card->dev in atmel_pdmic_asoc_card_init, but when
calling snd_soc_register_card,the function
dev_set_drvdata(card->dev, card) will do the same copy operation,
so i think that the former copy operation can be removed.Signed-off-by: Peng Donglin

This breaks devicetree compatibility, but in this case that is ok. All
affected units are either on my desk, or running an even older version
of the driver that is not compatible with the upstreamed version anyway
(and when these other units are eventually updated, they will get a
fresh dtb as well, so that is not a significant problem either).All of that is of course assuming that noone else has managed to build
something that can use this driver, but that seems extremely improbable.Signed-off-by: Peter Rosin
