Masahiro Yamada 4c11edfcf7 Remove MODULE_ALIAS() calls that take undefined macro
These files do not define (USBHS_)DRIVER_NAME. Yet, they can be
successfully compiled because they are never built as a module by
anyone, i.e, the MODULE_ALIAS() calls are always no-op.

A problem showed up when a patch "moduleparam: Save information about
built-in modules in separate file" was applied. With this new feature,
MODULE_*() will be populated even if the callers are built-in.

To avoid the build errors, the lines referencing to the undefined
macro must be removed.

The complete fix is to remove all MODULE_* and #include <linux/module.h>
like many "make ... explicitly non-modular" commits did.

For now, I am touching only the offending lines.

Tony Lindgren 44773ba170 ARM: OMAP2+: Drop unused pm-noop
Looks like these functions don't do anything in the mainline kernel so
we can just drop it.

Note that we must now also remove ir-rx51 pdata as it relies on the dummy
platform data that does not do anything. And ir-rx51 is calling a pdata
callback that doesn't do anything without checking if it exists first.

For configuring device specific minimal latencies, the interface to use
is pm_qos_add_request(). For an example, see what was done in commit
9834ffd1ec ("ASoC: omap-mcbsp: Add PM QoS support for McBSP to prevent
glitches"). I've added some comments to ir-rx51 so people using it can
add pm_qos support and test it.

Linus Torvalds 167569343f ARM: SoC platform updates for 4.17
This release brings up a new platform based on the old ARM9 core: the
 Nuvoton NPCM is used as a baseboard management controller, competing
 with the better known ASpeed AST2xx series.
 
 Another important change is the addition of ARMv7-A based chips
 in mach-stm32. The older parts in this platform are ARMv7-M based
 microcontrollers, now they are expanding to general-purpose workloads.
 
 The other changes are the usual defconfig updates to enable additional
 drivers, lesser bugfixes. The largest updates as often are the ongoing
 OMAP cleanups, but we also have a number of changes for the older
 PXA and davinci platforms this time.
 
 For the Renesas shmobile/r-car platform, some new infrastructure
 is needed to make the watchdog work correctly.
 
 Supporting Multiprocessing on Allwinner A80 required a significant
 amount of new code, but is not doing anything unexpected.

Tony Lindgren eb85a355c3 ARM: OMAP: Fix SRAM W+X mapping
We are still using custom SRAM code for some SoCs and are not marking
the PM code mapped to SRAM as read-only and executable after we're
done. With CONFIG_DEBUG_WX=y, we will get "Found insecure W+X mapping
at address" warning.

Let's fix this issue the same way as commit 728bbe75c8 ("misc: sram:
Introduce support code for protect-exec sram type") is doing for
drivers/misc/sram-exec.c.

On omap3, we need to restore SRAM when returning from off mode after
idle, so init time configuration is not enough.

And as we no longer have users for omap_sram_push_address() we can
make it static while at it.

Note that eventually we should be using sram-exec.c for all SoCs.

from plat-omap into mach-omap1. The hwmod is a concept only
applicable for OMAP2 platforms, and the omap_i2c_reset() is
already declared in mach-omap2/i2c.h. So, move the current
plat/i2c.h header file into the mach-omap1 folder, and adjust
the header usage accordingly.

The omap_timer_capability_dev_attr data was used to supply instance
specific capabilities (like always-on, PWM functionality or ability
to interrupt DSP cores) for legacy non-DT devices. These capabilities
are now provided through device-tree properties. The legacy device
support has been cleaned up in commit 8d39ff3d16 ("ARM: OMAP2+:
Remove unused legacy code for timer") and this data is therefore
no longer needed. So, cleanup the structure and all the associated
data in various hwmod data files.

While at this, remove the stale header in hwmod data files that
already do not have any timer capability data.

   it is intended for "Smart Hardware"
 - Broadcom Hurricane 2 (Aka Strataconnect BCM5334X) is a family

 uniprocessor operation.

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:

   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.

Linus Torvalds b3345d7c57 ARM: SoC platform changes for 3.17
This is the bulk of new SoC enablement and other platform changes for 3.17:
 
 * Samsung S5PV210 has been converted to DT and multiplatform
 * Clock drivers and bindings for some of the lower-end i.MX 1/2 platforms
 * Kirkwood, one of the popular Marvell platforms, is folded into the
   mvebu platform code, removing mach-kirkwood.
 * Hwmod data for TI AM43xx and DRA7 platforms.
 * More additions of Renesas shmobile platform support
 * Removal of plat-samsung contents that can be removed with S5PV210 being
   multiplatform/DT-enabled and the other two old platforms being removed.
 
 New platforms (most with only basic support right now):
 
 * Hisilicon X5HD2 settop box chipset is introduced
 * Mediatek MT6589 (mobile chipset) is introduced
 * Broadcom BCM7xxx settop box chipset is introduced
 
 + as usual a lot other pieces all over the platform code.

Nishanth Menon 76be4a5415 ARM: OMAP2+: DMA: remove requirement of irq for platform-dma driver
we have currently 2 DMA drivers that try to co-exist.
drivers/dma/omap-dma.c which registers it's own IRQ and is device tree
aware and uses arch/arm/plat-omap/dma.c instance created by
arch/arm/mach-omap2/dma.c to maintain channel usage (omap_request_dma).

Currently both try to register interrupts and mach-omap2/plat-omap dma.c
attempts to use the IRQ number registered by hwmod to register it's own
interrupt handler.

Now, there is no reasonable way of static allocating DMA irq in GIC
SPI when we use crossbar. However, since the dma_chan structure is
freed as a result of IRQ not being present due to devm allocation,
maintaining information of channel by platform code fails at a later
point in time when that region of memory is reused.

So, if hwmod does not indicate an IRQ number, then, assume that
dma-engine will take care of the interrupt handling.

Tony Lindgren 9ce2482fc6 ARM: OMAP2+: Fix DMA hang after off-idle
Commit 6ddeb6d844 (dmaengine: omap-dma: move IRQ handling to omap-dma)
added support for handling interrupts in the omap dmaengine driver
instead of the legacy driver. Because of different handling for
interrupts this however caused omap3 to hang eventually after hitting
off-idle.

Any of the virtual 32 DMA channels can be assigned to any of the
four DMA interrupts. So commit 6ddeb6d844 made the omap dmaengine
driver to use the second DMA interrupt while keeping the legacy code
still using the first DMA interrupt.

This means we need to save and restore both IRQENABLE_L1 in addition
to IRQENABLE_L0. As there is a chance that the DSP might be using
IRQENABLE_L2 or IRQENABLE_L3 lines, let's not touch those until
this has been confirmed. Let's just add a comment to the code for
now.

All OMAP IP blocks expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap
it if host operates in BE mode.

Changes are trivial sed like replacement of __raw_xxx functions
with xxx_relaxed variant.
