1ac051631a media: get rid of i2c-addr.h
In the past, the same I2C address were used on multiple places.
After I2C rebinding changes, this is no longer needed. So, we
can just get rid of this header, placing the I2C address where
they belong, e. g. either at bttv driver or at tvtuner.

1cb26030f3 media: i2c: enable i2c IR for hardware which isn't HD-PVR
This is a fix for commit 329d88da4d ("[media] media: i2c: Don't export
ir-kbd-i2c module alias") that stopped the module from being loaded
automagically.

The problems described only affect the HD-PVR, so it should not affect
other hardware; also if the module happens to be loaded, the i2c IR
part of the HD-PVR will be enabled anyway.

Fixes: 329d88da4d ("[media] media: i2c: Don't export ir-kbd-i2c module alias")

acaa34bf06 media: rc: implement zilog transmitter
This code implements the transmitter which is currently implemented
in the staging lirc_zilog driver.

The new code does not need a signal database, iow. the
haup-ir-blaster.bin firmware file is no longer needed, and the driver
does not know anything about the keycodes in that file.

Instead, the new driver can send raw IR, but the hardware is limited
to few different lengths of pulse and spaces, so it is best to use
generated IR rather than recorded IR.

ab5222ed16 media: merge ir_tx_z8f0811_haup and ir_rx_z8f0811_haup i2c devices
These two devices ids are really just one device with multiple
addresses. Probing becomes much simpler if we simply fold this into
one i2c device with two address.

Note that this breaks the lirc_zilog driver, however we will teach
ir-kbd-i2c to do what lirc_zilog does in a later commit.

afc7f24c01 media: rc: i2c: set parent of rc device and improve name
With the parent set for the rc device, the messages clearly state
that it is attached via i2c. The additional printk is unnecessary.

These are the old messages:

rc rc1: i2c IR (Hauppauge WinTV PVR-150 as /devices/virtual/rc/rc1
ir-kbd-i2c: i2c IR (Hauppauge WinTV PVR-150 detected at i2c-10/10-0071/ir0 [ivtv i2c driver #0]

Now we simply get:

rc rc1: Hauppauge WinTV PVR-150 as /devices/pci0000:00/0000:00:1e.0/0000:02:00.0/i2c-10/10-0071/rc/rc1

Note that we no longer copy the name. I've checked all call sites
to verfiy this is not a problem.

29236349aa media: ov9650: fix bogus warnings
The smatch logic gets confused with the syntax used to check if the
ov9650x_read() reads succedded:
	drivers/media/i2c/ov9650.c:895 __g_volatile_ctrl() error: uninitialized symbol 'reg2'.
	drivers/media/i2c/ov9650.c:895 __g_volatile_ctrl() error: uninitialized symbol 'reg1'.

There's nothing wrong with the original logic, except that
it is a little more harder to review.

So, let's stick with the syntax that won't cause read
issues.

00b4bac78f media: imx274: don't randomly return if range_count is zero
As smatch reported:
	drivers/media/i2c/imx274.c:659 imx274_regmap_util_write_table_8() error: uninitialized symbol 'err'.

There is a bug at imx274_regmap_util_write_table_8() with causes
it to randomly return a random error if range_count is zero.

Worse than that, the logic there starts with range_count
equal to zero, and periodically resets it to zero again.

As it is a way more likely that err assumes a non-zero value,
I suspect that the chance of this code to run is very small,
so, it would be worth to review the entire function.

Anyway, clearly it shouldn't be returning error if range_count
is zero. So, let's fix it.

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:

   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.

These types devices aren't directly related to the sensor, but are
nevertheless handled by the smiapp driver due to the relationship of these
component to the main part of the camera module --- the sensor.

This does not yet address providing the user space with information on how
to associate the sensor or lens devices but the kernel now has the
necessary information to do that.

The test_pattern_menu[] array has two valid items and a null terminated

v4l2_ctrl_new_std_menu_items() should be one.  However,
'ARRAY_SIZE(test_pattern_menu) - 1' is actually passed and it's not

Fix it by removing unnecessary terminated entry and let the correct

7bc9f038d0 media: i2c: OV5647: ensure clock lane in LP-11 state before streaming on
When I was supporting Rpi Camera Module on the ASUS Tinker board,
I found this driver have some issues with rockchip's mipi-csi driver.
It didn't place clock lane in LP-11 state before performing
D-PHY initialisation.

>From our experience, on some OV sensors,
LP-11 state is not achieved while BIT(5)-0x4800 is cleared.

So let's set BIT(5) and BIT(0) both while not streaming, in order to
coax the clock lane into LP-11 state.

0x4800 : MIPI CTRL 00
	BIT(5) : clock lane gate enable
		0: continuous
		1: none-continuous
	BIT(0) : manually set clock lane
		0: Not used
		1: used
