Pull "ARM: driver specific updates" from Arnd Bergmann:
"These are all specific to some driver. They are typically the
platform side of a change in the drivers directory, such as adding a
new driver or extending the interface to the platform. In cases where
there is no maintainer for the driver, or the maintainer prefers to
have the platform changes in the same branch as the driver changes,
the patches to the drivers are included as well.
A much smaller set of driver updates that depend on other branches
getting merged first will be sent later.
The new export of tegra_chip_uid conflicts with other changes in
fuse.c. In rtc-sa1100.c, the global removal of IRQF_DISABLED
conflicts with the cleanup of the interrupt handling of that driver.

Pull "ARM: board specific updates" from Arnd Bergmann/Olof Johansson:
"These changes are all specific to one board only. We're trying to
keep the number of board files low, but generally board level updates
are ok on platforms that are working on moving towards DT based
probing, which will eventually lead to removing them.
The board-ams-delta.c board file gets a conflict between the removal
of ams_delta_config and the addition of a lot of other data. The
Kconfig file has two changes in the same line, and in exynos, the

reasonable.
- Getting rid of the NO_IRQ crap from AMBA primecell stuff.

Pull PCI changes (including maintainer change) from Jesse Barnes:
"This pull has some good cleanups from Bjorn and Yinghai, as well as
some more code from Yinghai to better handle resource re-allocation
when enabled.
There's also a new initcall_debug feature from Arjan which will print
out quirk timing information to help identify slow quirks for fixing
or refinement (Yinghai sent in a few patches to do just that once the
new debug code landed).
Beyond that, I'm handing off PCI maintainership to Bjorn Helgaas.
He's been a core PCI and Linux contributor for some time now, and has
kindly volunteered to take over. I just don't feel I have the time
for PCI review and work that it deserves lately (I've taken on some
other projects), and haven't been as responsive lately as I'd like, so
I approached Bjorn asking if he'd like to manage things. He's going
to give it a try, and I'm confident he'll do at least as well as I
have in keeping the tree managed, patches flowing, and keeping things
stable."

Commit 4a53f4e "USB: ehci-tegra: add probing through device tree" added
AUXDATA for Tegra's USB/EHCI controller. However, it pointed the platform
data at a location containing the address of the intended platform data,

tegra_pcie_enable_controller() function type has been changed from
void to int, but the last return statement wasn't converted, so

use usleep_range for delay, and lower the value of timeout to 300ms

Several platforms create IOMEM defines for casting to 'void __iomem *',
and other platforms are incorrectly using __io() macro for the same
purpose. This creates a common definition and removes all the platform
specific versions. Rather than try to make linux/io.h and asm/io.h
assembly safe, the assembly version of IOMEM is moved into
asm/assembler.h.

Tegra PCIe driver waits for PLL to lock using busy loop.
If PLL fails to lock for some reason, this leads to silent lockup
while booting (as PCIe code is not modular).
Fix by adding timeout, so if PLL doesn't lock in a couple
of seconds, just PCIe driver fails and machine continues to boot.

Commit 6e96aca397 (arm/tegra: Harmony PCIe: Don't touch pinmux)
removed runtime tri-state toggling for PCIe related pinmux groups,
but it seems that the fact that all of them are tri-state by default
has been overlooked. Change defaults for these groups to TEGRA_TRI_NORMAL.

This adds a driver for the Tegra pinmux, and required parameterization
data for Tegra20 and Tegra30.
The driver is initially added with driver name and device tree compatible
value that won't cause this driver to be used. A later change will switch
the pinctrl driver to use the correct values, switch the old pinmux
driver to be disabled, and update all code that uses the old pinmux APIs
to use the new pinctrl APIs.

Tegra board updates. Most of the board updates for tegra30 and for some
of the driver device-tree conversions have gone in through the other

of updates to the not-yet-converted tegra2 boards and a couple of
device-tree updates.

The ports are used as follows:
UART1/A: Routed to debug dongle
UART2/B: GPS
UART3/C: Bluetooth
UART4/D: Routed to debug dongle
UART5/E: Not connected
The debug dongle has jumpers to connect either UART1/A or UART4/D to
the DB-9 connector. UART1/A is typically used on Cardhu, and is the option
we assume here.
For now, only enable UART1/A, and explicitly disable all other ports.
The explicit disable prevents the message "of_serial 70006040.serial:
no clock-frequency property set" being printed during boot.
Enabling the other ports requires their clocks to be enabled, or accesses
to the registers will hang. At present, this requires adding entries into
board-dt-tegra30.c's tegra_dt_clk_init_table[]. Lets punt on that and wait
for the common clock bindings to set this all up, although that will also
requiring adding clock support to 8250.c.
While we're at it, fix board-dt-tegra30.c to enable the correct clock for
the debug UART. We got away with this before, because the bootloader already
enabled it.

board-dt-tegra*.c should support any board using Tegra when booted using
device tree. Instead of explicitly listing all the supported boards,
which requires a kernel change for each new board, list the supported SoC
model instead.
Note that the board files do currently have explicit support for setting
up each board's pinmux. However, it's fairly likely that at least the
basic devices on any new board will work just fine as set up by the boot-
loader, and the pinmux data should be moving into device tree soon anyway.

USB: transceiver changes for 3.4
Here we have a big rework done by Heikki Krogerus (thanks) which
splits OTG functionality away from transceivers.
We have known for quite a long time that struct otg_transceiver was
a bad name for the structure, considering transceiver is far from
being OTG-specific (see 4e67185).
