ASoC: samsung: i2s: Fix rclk_srcrate handling
As the RCLK clock may be updated through the common clk API before each
snd_soc_dai_ops::trigger call, it is not enough to update i2s->rclk_srcrate
only once after it has been initially set to 0. To avoid wrong PSR values
we always get RCLK frequency from the CLK_I2S_RCLK_SRC clock, when that
clock is available.

the CLK_SCLK_I2S1 leaf clock, the exynos5433 clock tree

The device tree parsing part is changed is a way it supports older

ASoC: samsung: i2s: Ensure names of supplied clocks are unique
In order to support multiple instances of the I2S IP block the platform
device name is prepended to each clock registered by the driver.
The clock-output-names property is now not used, this should not cause
any issues as, for example, CDCLK clock is referenced through DT 'clocks'
property, not by name.

This change allows to have both I2S0 and I2S1 enabled simultaneously
on exynos5433 and working properly when #clock-cells property is specified
in respective DT nodes.

ASoC: samsung: i2s: Ensure the RCLK rate is properly determined
If the RCLK mux clock configuration is specified in DT and no set_sysclk()
callback is used in the sound card driver the sclk_srcrate field will remain
set to 0, leading to an incorrect PSR divider setting.
To fix this the frequency value is retrieved from the CLK_I2S_RCLK_SRC clock,
so the actual RCLK mux selection is taken into account.

Greg Kroah-Hartman b24413180f License cleanup: add SPDX GPL-2.0 license identifier to files with no license
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 <5
   lines).

All documentation files were explicitly excluded.

The following heuristics were used to determine which SPDX license
identifiers to apply.

 - when both scanners couldn't find any license traces, file was
   considered to have no license information in it, and the top level
   COPYING file license applied.

   For non */uapi/* files that summary was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0                                              11139

   and resulted in the first patch in this series.

   If that file was a */uapi/* path one, it was "GPL-2.0 WITH
   Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0 WITH Linux-syscall-note                        930

   and resulted in the second patch in this series.

 - if a file had some form of licensing information in it, and was one
   of the */uapi/* ones, it was denoted with the Linux-syscall-note if
   any GPL family license was found in the file or had no licensing in
   it (per prior point).  Results summary:

   and that resulted in the third patch in this series.

 - when the two scanners agreed on the detected license(s), that became
   the concluded license(s).

 - when there was disagreement between the two scanners (one detected a
   license but the other didn't, or they both detected different
   licenses) a manual inspection of the file occurred.

 - In most cases a manual inspection of the information in the file
   resulted in a clear resolution of the license that should apply (and
   which scanner probably needed to revisit its heuristics).

 - When it was not immediately clear, the license identifier was
   confirmed with lawyers working with the Linux Foundation.

 - If there was any question as to the appropriate license identifier,
   the file was flagged for further research and to be revisited later
   in time.

In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.

Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.  The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.

Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.

In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.

Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
 - a full scancode scan run, collecting the matched texts, detected
   license ids and scores
 - reviewing anything where there was a license detected (about 500+
   files) to ensure that the applied SPDX license was correct
 - reviewing anything where there was no detection but the patch license
   was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
   SPDX license was correct

This produced a worksheet with 20 files needing minor correction.  This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.

These .csv files were then reviewed by Greg.  Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected.  This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.)  Finally Greg ran the script using the .csv files to
generate the patches.

Marek Szyprowski 064970a0aa ASoC: samsung: i2s: disable secondary DAI until it gets fixed
Secondary DAI in Exynos I2S driver is not used by any of the currently
supported boards and it causes problems due to some limitations in the
ASoC code. Disable it until it gets proper support both by board-specific
and ASoC core code. Also disable IDMA support, which relies on secondary
DAI presence.

Jaechul Lee e8d9320890 ASoC: samsung: Use 'samsung-i2s' cpu_dai for dai_links
Add specific cpu_dai_name to dai_link because samsung i2s driver registers
two dais and components. Selecting one of them clearly is needed more
information like cpu_dai_name, of_node. The reason why the dai_links have
to use 'samsung-i2s' for cpu_dai is that 'samsung-i2s-sec' doesn't have a
capture functionality.

Without this code, cpu_dai will be selected the first one of the
component_list. For example, if I describe nothing to cpu_dai_name,
'samsung-i2s-sec' might be selected to HiFi Primay.

Jaechul Lee 22289ddcd8 ASoC: samsung: i2s: Use specific name for i2s dais
Add specific dais name when components are registered. Component and dai
name will follow their parent dev name, if the name isn't described.  In
case of this driver, each dais will have same name like '11440000.i2s0' by
fmt_single_name function.

The problem having same name is that TM2 machine driver can't detect
capture devices correctly. Machine driver doesn't know which one is proper
to use for cpu dai. The driver just selects to use 'samsung-i2c-sec' that
doesn't have capture functionality because the component of
samsung-i2s-sec is located in the first of the component_list.

I add dai name like 'samsung-i2s', 'samsung-i2s-sec' for each dais. The
reason why adding dai id to 1 is that it doesn't allow to use particular
dai name in case of when I use 0 for dai id.

of the audio root clock PLL. This can work now after the clock tree
definitions have been updated to allow clock rate setting propagation
on the path from the I2S controller up to the EPLL.

This patch also lowers the CODEC master clock frequency so as
to not exceed the maximum allowed 60 MHz at maximum audio sampling

Krzysztof Kozlowski 776bac64bf ASoC: samsung: Fix possible double iounmap on s3c24xx driver probe failure
Commit 87b132bc03 ("ASoC: samsung: s3c24{xx,12}-i2s: port to use
generic dmaengine API") moved ioremap() call from
s3c-i2s-v2.c:s3c_i2sv2_probe() to s3c2412-i2s.c:s3c2412_iis_dev_probe()
and converted it to devm- resource managed interface.

However the error path in first of them - s3c_i2sv2_probe() - was not
updated.  If getting a iis clock in s3c_i2sv2_probe() failed, the
address space would be unmapped there.  This could lead to:
1. double iounmap() later from devm-interface of s3c2412_iis_dev_probe()),
2. accessing the memory by other functions in s3c2412-i2s.c unit.

Anyway, the owner of this mapped region should be s3c2412-i2s.c because
it starts the mapping.

Affected are drivers for S3C24xx family although issue was not reproduced.
