return type of wait_for_completion_timeout is unsigned long not int, this
patch uses the return value of wait_for_completion_timeout in the condition
directly rather than assigning it to an incorrect type variable.
The variable used for handling the return of wait_for_cmpletion_timeout
was int but should be unsigned long, where it was not in use for
anything else and the return value in case of completion (>0) is not
used it was removed and wait_for_completion_timeout() used directly in
the if condition.
To make the timeout values a bit simpler to read and also handle all of
the corner cases correctly the declarations are moved to
msecs_to_jiffies().
The timeout declaration cleanup is just for readability

Even if bus is not hot-pluggable, the devices can be unbound from the
driver via sysfs, so we should not be using __exit annotations on
remove() methods. The only exception is drivers registered with
platform_driver_probe() which specifically disables sysfs bind/unbind
attributes.

Two config options exist to define powerpc MPC8xx:
* CONFIG_PPC_8xx
* CONFIG_8xx
In addition, CONFIG_PPC_8xx also defines CONFIG_CPM1 as
communication co-processor
arch/powerpc/platforms/Kconfig.cputype has contained the following
comment about CONFIG_8xx item for some years:
"# this is temp to handle compat with arch=ppc"
It looks like not many places still have that old CONFIG_8xx used,
so it is likely to be a good time to get rid of it completely ?

If a NAND device is not really present or pin muxes are not correctly
configured we can lock up the kernel waiting infinitely for NAND_STATUS
to be ready.
This can be easily reproduced on TI's DRA7-evm board by booting it
without NAND support in u-boot and disabling NAND pin muxes in the kernel.
Add timeout when waiting for NAND_CMD_RESET completion. As per ONFi v4.0
tRST can be upto 250ms for EZ-NAND and 5ms for raw NAND.

We're not initializing the ooblen field. Our users don't care, since
they check that oobbuf == NULL first, but it's good practice to zero
unused fields out.
We can drop the NULL initializations since we're memset()ing the whole
thing.

The PARAM command was long unimplemented and it probably wasn't
noticed because chip probing using only the few bytes returned by the
READID command are good enough in most cases to determine the chip in
use.
Still to notice such a shortcoming earlier in the future would be nice
in case it's something more vital.

The mxc-nand driver never supported the PARAM command to read out the
ONFI parameter page and so always relied on probing my manufacturer and
device id (as provided by the READID command).
This patch implements reading out the first parameter page copy at least
which should be good enough in practise.
This makes the boot log change from
nand: device found, Manufacturer ID: 0x2c, Chip ID: 0xb1
nand: Micron NAND 128MiB 1,8V 16-bit
to
nand: device found, Manufacturer ID: 0x2c, Chip ID: 0xb1
nand: Micron MT29F1G16ABBDAH4

The mxc-nand controller works pagewise and so usually only sends
commands to the flash chip with column == 0. A request with column != 0
from the upper layer is then fulfilled by indexing appropriately into the
device's RAM buffer.
To be able to access the ONFI marker at offset 0x20 in reply to the
READID command however it's invalid to read 32 bytes starting from
column 0.
So let the function used to send the address cycles send the column
address actually passed instead of 0 and fix all callers to pass 0
instead appropriately. Also add some warnings in case this patch changes
the drivers semantics.

When the hardware operates in 16 bit mode it always reads 16 bits even
for operations that only have the lower 8 bits defined. So the upper
bits must be discarded. Do this in the read_byte callback instead of
when reading the NAND id to support reading byte wise more than 5 bytes
and at other occations (like reading the ONFI parameter page).

At least on i.MX25 (i.e. NFCv2) preset_v2 is called with mtd->writesize
== 0 that is before the connect flash chip is detected. It then
configures for 8 bit ECC mode which needs 26 bytes of OOB per 512 bytes
main section. For flashes with a smaller OOB area issuing a read page
command makes the controller stuck with this config.
Note that this currently doesn't hurt because the first read page
command is issued only after detection is complete and preset is called
once more.

While extending the mxc-nand driver it happend to me a few times that
the device was stuck and this made the machine hang during boot. So
implement a timeout and print a stack trace the first time this happens

changed to int to be able to handle the timeout in the caller.

As the devicetree binding doesn't require num_cs to exist or be strictly
positive, and neither does the platform data case, a bug appear when
num_cs is set to 0 and panics the kernel.
The issue is that in alloc_nand_resource(), chip is dereferenced without
having a value assigned when num_cs == 0.
Fix this by returning ENODEV is num_cs == 0.
The panic seen is :

Change the handling of the data stage in the driver : don't pump data in
the top-half interrupt, but rather schedule a thread for non dma cases.
This will enable latencies in the data pumping, especially if delays are
required. Moreover platform shall be more reactive as other interrupts
can be served while pumping data.
No throughput degradation was observed, at least on the zylonite
platform, while a slight degradation was being expected.

The NDDB register holds the data that are needed by the read and write
commands.
However, during a read PIO access, the datasheet specifies that after each 32
bytes read in that register, when BCH is enabled, we have to make sure that the
RDDREQ bit is set in the NDSR register.
This fixes an issue that was seen on the Armada 385, and presumably other mvebu
SoCs, when a read on a newly erased page would end up in the driver reporting a
timeout from the NAND.

Pull one more batch of power management and ACPI updates from Rafael Wysocki:
"These are mostly fixes on top of the previously merged recent PM and
ACPI material.
First, one commit that broke the ACPI LPSS (Low-Power Subsystem)
driver on a Dell box is reverted and there are two stable-candidate
fixes for that driver. Another fix cleans up two recently added ACPI
EC messages that look odd and the printk level of a noisy debug
message in the core ACPI resources handling code is reduced.
In addition to that we have two stable-candidate fixes for the s3c
cpufreq driver, two cpuidle powernv driver updates related to Device
Trees and a PNP subsystem cleanup that will allow us to get rid of
some old ugliness going forward. Also there is a new blacklist entry
for the ACPI backlight code.
Specifics:
- Revert a recent ACPI LPSS driver commit that prevented the touchpad
driver from loading on Dell XPS13 (Jarkko Nikula).
- Make the ACPI LPSS driver disable the I2C controllers and deassert
SPI host controllers resets at startup on Intel BayTrail and
Braswell SoCs in case they have been left in wrong states by the
platform firmware which then may casuse fatal controller driver
failures during resume from hibernation (Mika Westerberg).
- Make two recently added ACPI EC messages look better (Scot Doyle).
- Reduce the printk level of a recently added debug message related
to ACPI resources that may become noisy in some cases (Rafael J
Wysocki).
- Add a new ACPI backlight blacklist entry for Samsung Series 9
(900X3C/900X3D/900X3E/900X4C/900X4D) laptops where the native
backlight interface doesn't work while the ACPI based one does
(Jens Reyer).
- Make the PNP sybsystem's core code use __request_region() followed
by __release_region() instead of __check_region() which then will
allow us to get rid of the latter as it has no more users (Jakub
Sitnicki).
- Fix a build breakage and an issue with two __init functions that
may be called after initialization in the s3c cpufreq driver (Arnd
Bergmann).
- Make the powernv cpuidle driver read target_residency values for
idle states from a Device Tree (as we have the suitable DT bindings
for that now) and improve the parsing of the powermgmt DT node in
that driver (Preeti U Murthy)"

git://git.linaro.org/people/mike.turquette/linux
Pull clock framework updates from Mike Turquette:
"The clock framework changes contain the usual driver additions,
enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
devices.
Additionally the framework core underwent a bit of surgery with two
major changes:
- The boundary between the clock core and clock providers (e.g clock
drivers) is now more well defined with dedicated provider helper
functions. struct clk no longer maps 1:1 with the hardware clock
but is a true per-user cookie which helps us tracker users of
hardware clocks and debug bad behavior.
- The addition of rate constraints for clocks. Rate ranges are now
supported which are analogous to the voltage ranges in the
regulator framework.
Unfortunately these changes to the core created some breakeage. We
think we fixed it all up but for this reason there are lots of last
minute commits trying to undo the damage"
