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.

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.

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:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
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.

to use 'samsung-i2s' for cpu_dai is that 'samsung-i2s-sec' doesn't have a

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.

As suggested in reviews the requirement of clocks in the 'sound' node

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

Commit 87b132bc03 ("ASoC: samsung: s3c24{xx,12}-i2s: port to use

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.

This reverts commit cdaf9af1ea
which breaks I2S support on the non-DT Samsung SoC platforms,
since the default "tx", "rx" DMA channel names for playback
and capture streams or custom channel names in struct
snd_dmaengine_pcm_config are supported in the ASoC dmaengine
module only for devicetree booting case.

This patch adds pointer to I2S device to clk_register_* functions.
This in the future allow clock framework to ensure proper runtime state
of the I2S device during all operations on the clocks provided by I2S
module.

This patch adds handling of parent operational clock to runtime PM
callbacks. This way it is ensured that when I2S module is in runtime
suspended state, all its parent clocks are disabled and unprepared.

This patch moves saving and restoring I2S registers to runtime PM
operations, what prepares the driver to operate with audio power domain.
When support for audio power domain is enabled and the domain is being
turned off, the I2S module will loose its context (registers), so runtime
callbacks have to handle it. System sleep suspend/resume operation are
implemented on top of runtime PM operations with generic
pm_runtime_force_suspend/resume helpers.

This patch adds calls to pm_runtime_get/put to ensure that any access to
I2S registers is done with proper (active) runtime PM state of I2S device.
Till now the driver enabled runtime PM, but didn't manage the state during
driver operation. The driver worked fine only because the runtime PM
callbacks managed device clock, which was enabled all the time because of
the additional enable call in the driver's probe function.

For some unknown (maybe historical?) reasons support for secondary I2S DAI
was implemented by adding additional virtual platform device, which was
then probed again with the main I2S driver. This pattern is really hard
to follow and provides no benefits, so lets remove this hack and register
both DAIs during linear probe of Exynos I2S controller driver.

The driver was checking for non-NULL address of struct's members:
- s3c_audio_pdata->type (union),
- s3c_audio_pdata->type.i2s (embedded struct).
This is pointless as these will be always non-NULL. The 's3c_audio_pdata'
is always initialized in static memory so it will be zeroed.
Additionally the 'type' member was an union with only one member.
It is safe to reorganize the structures to get rid of useless union and
checks for addresses to fix the coccinelle warning:
