Tony Lindgren fcc76a8506 ARM: OMAP1: Move omap_init_audio() to keep the devices in alphabetical order
The comments in omap1_init_devices() ask to keep the devices in
alphabetical order. Only omap_init_audio() is not following this,
so let's move it. No functional changes.

Laurent Pinchart b2f44dc29b ARM: OMAP: igep0020: Specify the VPLL2 regulator unconditionally
The supply is connected to the DSS DO-D5 pins and is thus needed for
both serial and parallel display interfaces on the igep0030 as well as
the igep0020.

If the igep0030 module isn't connected to a display, no DSI or DPI
display will be specified in board code, and the DSS driver won't enable
to VPLL2 regulator anyway.

Grazvydas Ignotas d723c17ab6 ARM: OMAP2+: remove incorrect irq_chip ack field
Each irq_chip for the main interrupt controller has offsets set for irq
masking registers, which added to respective base results in a pointer
to appropriate hardware register. However this is not correct for
INTC_CONTROL as there is only one INTC_CONTROL register. This does not
cause problems because generic ack code is never called, but remove
this assignment to avoid confusion.

Kevin Hilman 414e41286e ARM: OMAP2+: WDTIMER integration: fix !PM boot crash, disarm timer after hwmod reset
Without runtime PM enabled, hwmod needs to leave all IP blocks in an
enabled state by default so any driver access to the HW will succeed.
This is accomplished by seting the postsetup_state to enabled for all
hwmods during init when runtime PM is disabled.

Currently, we have a special case for WDT in that its postsetup_state
is always set to disabled.  This is done so that the WDT is disabled
and the timer is disarmed at boot in case there is no WDT driver.
This also means that when runtime PM is disabled, if a WDT driver *is*
built in the kernel, the kernel will crash on the first access to the
WDT hardware.

We can't simply leave the WDT module enabled, because the timer is
armed by default after reset. That means that if there is no WDT
driver initialzed or loaded before the timer expires, the kernel will
reboot.

To fix this, a custom reset method is added to the watchdog class of
omap_hwmod.  This method will *always* disarm the timer after hwmod
reset.  The WDT timer then will only be rearmed when/if the driver is
loaded for the WDT.  With the timer disarmed by default, we no longer
need a special-case for the postsetup_state of WDT during init, so it
is removed.

Any platforms wishing to ensure the watchdog remains armed across the
entire boot boot can simply disable the reset-on-init feature of the
watchdog hwmod using omap_hwmod_no_setup_reset().

Tested on 3530/Overo, 4430/Panda.

NOTE: on 4430, the hwmod OCP reset does not seem to rearm the timer as
documented in the TRM (and what happens on OMAP3.)  I noticed this
because testing the HWMOD_INIT_NO_RESET feature with no driver loaded,
I expected a reboot part way through the boot, but did not see a
reboot.  Adding some debug to read the counter, I verified that right
after OCP softreset, the counter is not firing.  After writing the
magic start sequence, the timer starts counting.  This means that the
timer disarm sequence added here does not seem to be needed for 4430,
but is technically the correct way to ensure the timer is disarmed, so
it is left in for OMAP4.

Special thanks to Paul Walmsley for helping brainstorm ideas to fix
this problem.

account when considering whether to go idle:

Kevin Hilman f0c54d31b0 ARM: OMAP: clock: convert AM3517/3505 detection/flags to AM35xx
To improve the clarity of the code, replace the CK_3517 flag used in
the clock data with CK_AM35XX.  The CK_3505 flag can also be
removed, since it is now unused.

Kevin Hilman c93a98c902 ARM: OMAP3: clock data: treat all AM35x devices the same
The init for 3505/3517 specific clocks depends on the ordering of
cpu_is checks, is error prone and confusing (there are 2 separate
checks for cpu_is_omap3505()).

Remove the 3505-specific checking since CK_3505 flag is not used, and
treat all AM35x clocks the same.

This means that the SGX clock (the only AM35x clkdev not currently
flagged for 3505) will now be registered on 3505, but that is
harmless.  That can be cleaned up when the clkdev nodes are removed in
favor of them being registered by hwmod.

The AM35x UART4 is common to all AM35x devices, so use CK_AM35XX instead
of (CK_3505 | CK_3517), which is equivalent.

Chris Mason b9fab919b7 Btrfs: avoid sleeping in verify_parent_transid while atomic
verify_parent_transid needs to lock the extent range to make
sure no IO is underway, and so it can safely clear the
uptodate bits if our checks fail.

But, a few callers are using it with spinlocks held.  Most
of the time, the generation numbers are going to match, and
we don't want to switch to a blocking lock just for the error
case.  This adds an atomic flag to verify_parent_transid,
and changes it to return EAGAIN if it needs to block to
properly verifiy things.

Jiri Slaby 49a5f3cf6a TTY: pdc_cons, fix regression in close
The test in pdc_console_tty_close '!tty->count' was always wrong
because tty->count is decremented after tty->ops->close is called and
thus can never be zero. Hence the 'then' branch was never executed and
the timer never deleted.

This did not matter until commit 5dd5bc40f3 ("TTY: pdc_cons, use
tty_port").  There we needed to set TTY in tty_port to NULL, but this
never happened due to the bug above.

So change the test to really trigger at the last close by changing the
condition to 'tty->count == 1'.

Well, the driver should not touch tty->count at all.  It should use
tty_port->count and count open count there itself.

Sasha Levin 377485f624 init: don't try mounting device as nfs root unless type fully matches
Currently, we'll try mounting any device who's major device number is
UNNAMED_MAJOR as NFS root.  This would happen for non-NFS devices as
well (such as 9p devices) but it wouldn't cause any issues since
mounting the device as NFS would fail quickly and the code proceeded to
doing the proper mount:

       [  101.522716] VFS: Unable to mount root fs via NFS, trying floppy.
       [  101.534499] VFS: Mounted root (9p filesystem) on device 0:18.

Commit 6829a048102a ("NFS: Retry mounting NFSROOT") introduced retries
when mounting NFS root, which means that now we don't immediately fail
and instead it takes an additional 90+ seconds until we stop retrying,
which has revealed the issue this patch fixes.

This meant that it would take an additional 90 seconds to boot when
we're not using a device type which gets detected in order before NFS.

This patch modifies the NFS type check to require device type to be
'Root_NFS' instead of requiring the device to have an UNNAMED_MAJOR
major.  This makes boot process cleaner since we now won't go through
the NFS mounting code at all when the device isn't an NFS root
("/dev/nfs").

Lin Ming 1cc0c998fd ACPI: Fix D3hot v D3cold confusion
Before this patch, ACPI_STATE_D3 incorrectly referenced D3hot
in some places, but D3cold in other places.

After this patch, ACPI_STATE_D3 always means ACPI_STATE_D3_COLD;
and all references to D3hot use ACPI_STATE_D3_HOT.

ACPI's _PR3 method is used to enter both D3hot and D3cold states.
What distinguishes D3hot from D3cold is the presence _PR3
(Power Resources for D3hot)  If these resources are all ON,
then the state is D3hot.  If _PR3 is not present,
or all _PR0 resources for the devices are OFF,
then the state is D3cold.

This patch applies after Linux-3.4-rc1.
A future syntax cleanup may remove ACPI_STATE_D3
to emphasize that it always means ACPI_STATE_D3_COLD.
