next/cleanup
From Vladimir Zapolskiy:
"The main change is a switchover to a common clock framework driver for
LPC32xx, this also allows to reuse a shared LPC32xx clockevent driver, and
hence remove legacy clock and timer drivers from arch/arm/mach-lpc32xx.
I'm adding an official LPC32xx maintainer Roland to Cc, however he seems
to be unresponsive for a quite long time (since 2014)."
* 'lpc32xx/soc' of https://github.com/vzapolskiy/linux:
arm: lpc32xx: remove direct control of GPIOs from shared mach file
arm: lpc32xx: remove selected HAVE_IDE
arm: lpc32xx: switch to common clock framework

Keyboard driver for GPIO buttons(gpio-keys) checks for the legacy
"gpio-key,wakeup" boolean property to enable gpio buttons as wakeup
source.
Few dts files assign value "1" to gpio-key,wakeup which is incorrect.
Since the presence of the boolean property indicates it is enabled,
value of "0" or "1" have no significance.
This patch replaces the legacy "gpio-key,wakeup" with the unified
"wakeup-source" property which inturn fixes the above mentioned issue.

On an MMIO access, we always copy the on-stack buffer info
the shared "run" structure, even if this is a read access.
This ends up leaking up to 8 bytes of uninitialized memory
into userspace, depending on the size of the access.
An obvious fix for this one is to only perform the copy if
this is an actual write.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
Two omap fixes for omaps against v4.5-rc5:
- Yet another fix for n900 onenand to avoid corruption. This time to
fix the issue of mounting onenand back and forth between the original
maemo kernel and mainline Linux kernel. And it also seems there will
be two more fixes coming via the MTD tree as issues were discovered
also in the onenand driver during testing.
- Revert tps65217 regulator clean up as it breaks MMC for am335x
variants. The proper way to clean this up is just to rename the
tps65217.dtsi file into tps65217-am335x.dtsi as a similar setup
is used on many am335x boards.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
Few fixes for omaps against v4.5-rc3:
- Improve omap_device error message to tell driver writers what is
wrong after commit 5de85b9d57ab ("PM / runtime: Re-init runtime PM
states at probe error and driver unbind"). There will be also a
handful of driver related fixes also queued separately. But adding
this error message makes it easy to fix any omap_device using
drivers suffering from this issue so I think it's important to
have.
- Also related to commit 5de85b9d57ab discussion, let's fix a bug
where disabling PM runtime via sysfs will also cause the hardware
state to be different from PM runtime state.
- Fix audio clocks for beagle-x15.
- Use wakeup-source instead of gpio-key,wakeup for the new entries
that sneaked in during the merge window.
- Fix a legacy booting vs device tree based booting regression for
n900 where the legacy user space expects to have the device
revision available in /proc/atags also when booted with device
tree.

Also, disable the I2C ancillary drivers auto-select option since the media

If syscon_config.max_register is initialized like it should be, we have
omap_ctrl_read/write() fail with out of range register access at least
for omap3.
We have omap3.dtsi setting up a regmap range for scm_conf, but we now
have omap_ctrl_read/write() also attempt to use the regmap. However,
omap_ctrl_read/write() is also used for other register ranges in the
system control module (SCM).
Let's fix the issue by just removing the regmap_read/write() usage for
control module as suggested by Tero Kristo <[email protected]>.

The "targets" exists to specify which files need the corresponding
".*_cmd" files to be included during the build. In other words, it
is used for files that need to detect the change of the command line
by if_changed, if_changed_dep, and if_changed_rule. While, these
files are just copied by "$(call cmd,shipped)". Adding them to the
"targets" is meaningless because $(call cmd,...) never creates
".*_cmd" files. Such files as ".lib1funcs.S.cmd", ".ashldi3.S.cmd"
do not exist in the first place.

When CONFIG_DEBUG_ICEDCC is set, we don't use the platform
specific putc() function, but use icedcc_putc() instead, so
putc is unused and causes a compile time warning:

arch/arm/mach-w90x900/include/mach/uncompress.h:30:13: warning: 'putc' defined but not used [-Wunused-function]
On most platforms, this does not happen, because putc is defined
as 'static inline' so the compiler will automatically drop it
when it's unused.
This changes the remaining seven platforms to behave the same way.
