lots of changes for the dwc3 driver which will make
the driver a lot more stable and some changes which
are just cosmetic.
The bulk of changes is related to mis-defined macros
which were never used before, some fixes to error path
which e.g. prevent the driver from initiating two
transfer on ep0out in case of stall, some fixes to
request dequeueing and the End Transfer Command.
We have some changes to U1/U2 handling where we were
enabling those transtions at the wrong spot (though
we haven't seen a problem from that as of today).
A few patches will make it easier to add support for
newer releases of the core by adding definitions for
new registers and changing the code to act accordingly
when certain revisions are detected.
There's also the usual comestic changes to make the
driver easier to maintain and make it easier for new-
comers to understand the driver. Also one patch fixing
a double inclusion of a header.

The “file” sysfs entry for LUNs was writable even for non-removable
LUNs and the fsg_store_file() function did not check whether LUN is
removable or not. This made it possible to change or even close
LUN's backing file.
The same is true for “ro” sysfs entry and LUNs simulating CD-ROM.
For those LUNs, the file should not be writable.
This commit introduces two new device_attribute structures for those
two special cases so that the file/ro sysfs entries are made
non-writable when not desired.

ACPI, x86: fix Dell M6600 ACPI reboot regression via DMI
ACPI sysfs.c strlen fix
The acpi_pad driver can get stuck in destroy_power_saving_task()
waiting for kthread_stop() to stop a power_saving thread. The problem
is that the isolated_cpus_lock mutex is owned when
destroy_power_saving_task() calls kthread_stop(), which waits for a
power_saving thread to end, and the power_saving thread tries to
acquire the isolated_cpus_lock when it calls round_robin_cpu(). This
patch fixes the issue by making round_robin_cpu() use its own mutex.

In commit 7a87982420 we added
a wrapper for the WDIOC_GETSTATUS ioctl call. The code results
however in a different behaviour: it returns an error if the
driver doesn't support the status operation. This is not
according to the API that says that when we don't support
the status operation, that we just should return a 0 value.
Only when the device isn't there anymore, we should return an

Commit e978aa7d7d ( cpuidle: Move
dev->last_residency update to driver enter routine; remove dev->last_state)
was breaking suspend on laptops, as reported in the below link
- https://lkml.org/lkml/2011/11/11/164
This was fixed in commit 3439a8da16
(ACPI / cpuidle: Remove acpi_idle_suspend (to fix suspend regression)
by removing acpi_idle_suspend flag.
- https://lkml.org/lkml/2011/11/14/74
But this did fix did not work on all systems
as Suspend/resume regression was reported on Lenovo S10-3
recently by Dave.
- https://lkml.org/lkml/2012/5/27/115
It looked like with commit e978aa7d broke suspend and
with commit 3439a8da resume was not working with acpi_idle driver.
This patch fixes the regression that caused this issue
in the first place. acpi_idle_suspend flag is essential on
some x86 systems to prevent the cpus from going to deeper C-states
when suspend is triggered ( commit b04e7bdb98 )
So reverting the commit 3439a8da is essential.
By default, irqs are disabled in cpu_idle arch specific call
and re-enabled in idle state return path . During suspend,
the acpi_idle_suspend flag is set, which
prevents the cpus from going to deeper idle states,
it is essential to enabling the irqs in this return path too.
To address the suspend issue,
we were not re-enabling the interrupts while returning from
acpi_idle_enter_bm() routine if acpi_idle_suspend flag is set.
and this caused suspend failure.
In addition to the above, to improve the readability of the code,
return of -ENIVAL is replaced with -EBUSY in acpi_idle_suspend
return path. Implying that the system is currently busy when suspend
is in progress, which prevents the cpus from entering deeper C-states.

The freescale arm i.MX series platform can support this driver, and
usually the arm cpu works in the little endian mode by default, while
device tree entry value is stored in big endian format, we should use
be32_to_cpup() to handle them, after modification, it can work well
both on the le cpu and be cpu.

The struct fhci_regs (in drivers/usb/host/fhci.h) is basically a redefinition
of the struct qe_usb_ctlr (in arch/powerpc/include/asm/immap_qe.h).
The qe_usb_ctlr struct is preferrable once it uses accurately the registers'
names found in the Freescale's QUICC Engine Block Reference Manuals (QEIWRM.pdf
Rev.4.4 Chapter 19 for MPC836xE series and MPC8323ERM.pdf Rev.2 Chapter 36 for
MPC832xE series), making easier to map the FHCI device driver to the hardware
manual. Also, as the FHCI driver uses the USB Controller registers, the name
qe_usb_ctlr is a more precise representation of the hardware than fhci_regs.

FCoE target mode was experiencing issues due to the fact that we were
sending up data frames that were padded to 60 bytes after the DDP logic had
already stripped the frame down to 52 or 56 depending on the use of VLANs.
This was resulting in the FCoE DDP logic having issues since it thought the
frame still had data in it due to the padding.
To resolve this, adding code so that we do not pad FCoE frames prior to
handling them to the stack.

This patch reverts the commit dba3c29ea4.
After bisecting, this commit dba3c29 is found to ruin micro-SD card data
(writing incorrect file, or fs is corrupt after several times mount)
on the beagle-xm revB, and reverting the commit will fix the problem.
Also from TRM of OMAP3/OMAP4/DM37x, the below is mentioned about
the Auto CMD12 Enable bit.
- SDIO does not support this feature.
- SD card only.
Looks it is not suitable to always enable Auto CMD12 in host controller
driver.
Considered that the commit is not mature enough, so ask to revert it
first.

If multi block write operation fails for SD card, during
error handling we send the SD_APP_SEND_NUM_WR_BLKS (ACMD22)
to know how many blocks were already programmed by card.
But mmc_sd_num_wr_blocks() function which sends the ACMD22
calculates the data timeout value from csd.tacc_ns and
csd.tacc_clks parameters which will be 0 for block addressed
(>2GB cards) SD card. This would result in timeout_ns and
timeout_clks being 0 in the mmc_request passed to host driver.
This means host controller would program its data timeout timer
value with 0 which could result in DATA TIMEOUT errors from
controller.
To fix this issue, mmc_sd_num_wr_blocks() should instead
just call the mmc_set_data_timeout() to calculate the
data timeout value. mmc_set_data_timeout() function
ensures that non zero timeout value is set even for
block addressed SD cards.
