The 4430 and 4460 version of PandaBoard mostly the same with
exception at least in audio setup.
Use the omap4-panda.dts file as a base and only override the differences
between the revisions.
For audio it is the name of the sound card and the routing information.

The MMC/SD and SPI entries in this file are not tested yet. They
inadvertently came into the patch because of some work in progress
stuff I had in my repo.
These entries should not have been sent out in the first place and
I am sorry for the trouble and will be extra careful in future.
Since the offending commit is not sent upstream yet, I hope this can
be merged into the commit 5fc0b42a98556bd9f01cecc6a64fcbd15ec363f0

We already use them for openat() and friends, but fchdir() also wants to
be able to use O_PATH file descriptors. This should make it comparable
to the O_SEARCH of Solaris. In particular, O_PATH allows you to access
(not-quite-open) a directory you don't have read persmission to, only
execute permission.
Noticed during development of multithread support for ksh93.

The documentation didn't actually mention how to enable no_new_privs.
This also adds a note about possible interactions between
no_new_privs and LSMs (i.e. why teaching systemd to set no_new_privs
is not necessarily a good idea), and it references the new docs
from include/linux/prctl.h.

File operations on /dev/ecryptfs would BUG() when the operations were
performed by processes other than the process that originally opened the
file. This could happen with open files inherited after fork() or file
descriptors passed through IPC mechanisms. Rather than calling BUG(), an
error code can be safely returned in most situations.
In ecryptfs_miscdev_release(), eCryptfs still needs to handle the
release even if the last file reference is being held by a process that
didn't originally open the file. ecryptfs_find_daemon_by_euid() will not
be successful, so a pointer to the daemon is stored in the file's
private_data. The private_data pointer is initialized when the miscdev
file is opened and only used when the file is released.

When pin control mapping tables are written the registered device
name is supplied for use in name-based searches within the pinctrl
driver. In the case of the DB8500 the string "pinctrl-db8500" is
used. However, when we register the driver with Device Tree, its
naming convention uses something that looks more like "pinctrl.2".
To work around the device naming inconsistencies between devices
registered via platform code and the ones registered by Device
Tree, we use AUXDATA to over-ride the Device Tree naming scheme.

Sometimes it doesn't make any sense for a node to have an address.
In this case device lookup will always be unsuccessful because we
currently assume every node will have a reg property. This patch
changes the semantics so that the resource address and the lookup
address will only be compared if one exists.
Things like AUXDATA() rely on of_dev_lookup to return the lookup
entry of a particular device in order to do things like apply
platform_data to a device. However, this is currently broken for
nodes which do not have a reg property, meaning that platform_data
can not be passed in those cases.

Whistler is a highly configurable Tegra evaluation and development board.
This change adds support for the following specific configuration:
E1120 motherboard

E1116 PMU board
The motherboard configuration switches are set as follows:
SW1=0 SW2=0 SW3=5
S1/S2/S3/S4 all on, except S3 7/8 are off.
Other combinations of daugher boards may work to varying degrees, but will
