Here is another fixes series for AT91 designed for 3.4-rc.
We experienced some issues while compiling some drivers as modules: Joachim has
corrected several of them. We may reduce this number of exported values by
reworking some drivers, in the future.
Some drivers are also modified here, I would like to keep them in the series
as the modifications are really related with our recent move to irqdomains or
simply related with compiler annotations.
I keep dmaengine Kconfig modification in this "fixes" series. The DMA
driver will not be available for 9x5 SoC family otherwise.

DMTIMER source selection on OMAP1 is broken. omap1_dm_timer_set_src()
tries to use __raw_{read,write}l() to read from and write to physical
addresses, but those functions take virtual addresses.
sparse caught this:
arch/arm/mach-omap1/timer.c:50:13: warning: incorrect type in argument 1 (different base types)
arch/arm/mach-omap1/timer.c:50:13: expected void const volatile [noderef] <asn:2>*<noident>
arch/arm/mach-omap1/timer.c:50:13: got unsigned int
arch/arm/mach-omap1/timer.c:52:9: warning: incorrect type in argument 1 (different base types)
arch/arm/mach-omap1/timer.c:52:9: expected void const volatile [noderef] <asn:2>*<noident>
arch/arm/mach-omap1/timer.c:52:9: got unsigned int
Fix by using omap_{read,writel}(), just like the other users of the
MOD_CONF_CTRL_1 register in the OMAP1 codebase. Of course, in the long term,
removing omap_{read,write}l() is the appropriate thing to do; but
this will take some work to do this cleanly.
Looks like this was caused by 97933d6 (ARM: OMAP1: dmtimer: conversion
to platform devices) that dangerously moved code and changed it in
the same patch.

The current serial UART code, while fidling with ocp idlemode bits,
forget about the smart idle wakeup bit even if it is supported by
UART IP block. This will lead to missing the module wakeup on OMAP's
where the smart idle wakeup is supported.
This was the root cause of the console sluggishness issue, I have been
observing on OMAP4 devices and also can be potential reason for some
other UART wakeup issues.

Commit (7496ba3 ARM: OMAP2+: UART: Add default mux for all uarts)
wrongly added muxing of default pads for all uarts. This causes
breakage on multiple boards using uart pins for alternate functions.
For example, on zoom3 random oopses can be seen with nfsroot as
the smsc911x ethernet FIFO timings on GPMC bus are controlled
by gpmc_wait2 and gpmc_wait3 pins. This means we can't mux these
pads to uart4 functionality as commit 7496ba3 was doing.
Not all boards tend to use all uarts and most of unused uart pins
are muxed for other purpose. This commit breaks the modules which
where trying to use unused uart pins on their boards.
So remove the default pad muxing. Note that this is not a complete
fix, as we now rely on bootloader set muxing for the uart wake-up
events. Further patching is needed to enable wake-up events for
uarts that are already muxed to uart mode.

Some new drivers and changed Kconfig dependencies for the v3.4

- The SOC config options are now brought in by default
- No need to explicitly select misc devices anymore
- I2C is selected by default

in this
- The regulator framework needs to be explictly selected

Currently when ThumbEE is not enabled (!CONFIG_ARM_THUMBEE) the ThumbEE
register states are not saved/restored at context switch. The default state
of the ThumbEE Ctrl register (TEECR) allows userspace accesses to the
ThumbEE Base Handler register (TEEHBR). This can cause unexpected behaviour
when people use ThumbEE on !CONFIG_ARM_THUMBEE kernels, as well as allowing
covert communication - eg between userspace tasks running inside chroot
jails.
This patch sets up TEECR in order to prevent user-space access to TEEHBR
when !CONFIG_ARM_THUMBEE. In this case, tasks are sent SIGILL if they try to
access TEEHBR.

During booting of cpu1, there is a short window where cpu1
is online, but not active where cpu1 is occupied by waiting
to become active. If cpu0 then decides to schedule something
on cpu1 and wait for it to complete, before cpu0 has set
cpu1 active, we have a deadlock.
Typically it's this CPU frequency transition that happens at
this time, so let's just not wait for it to happen, it will
happen whenever the CPU eventually comes online instead.

The atmel_mxt_ts driver has been extended to support more 'configuration
objects' in commit 81c88a711 ("Input: atmel_mxt_ts - update object list"),
what broke the configuration values for NURI board. These values are
optional anyway, so remove them to get the driver working correctly.

On some versions of NURI and UniversalC210 boards, camera clocks are
routed directly to xusbxti clock source. This patch sets the correct
value for this clock to let usb and camera sensors to work correctly and
avoid division by zero on driver's probe.

git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into fixes
A few OMAP hwmod fixes against v3.4-rc2. One of them is a reversion
of a previous v3.4-rc patch that caused some regressions, and upon
further review, appears not to be necessary. The other two are fairly
minor.

arm: msm: Fix section mismatch in smd.c.
fixes a section mismatch between the board file and the smd driver's
probe function, however, it misses the additional mismatches between
the probe function and some routines it calls. Fix these up as well.

Commit 94e5a85b ("ARM: earlier initialization of vectors page") made it
the responsibility of paging_init to initialise the vectors page.
This patch adds a call to early_trap_init for the !CONFIG_MMU case,
placing the vectors at CONFIG_VECTORS_BASE.

Some bootloaders are broken enough to expose an ATAG_MEM with

an unbootable system.

atags_to_fdt() returns 1 when it fails to find a valid FDT signature.
The CONFIG_ARM_ATAG_DTB_COMPAT code is supposed to retry with another
location, but only does so when the initial call doesn't fail.
Fix this by using the correct condition in the assembly code.

interface
The clocks for all DSS slave interfaces were recently changed to "dss_ick" on
OMAP2 and OMAP3, this clock can be autoidled by PRCM. The VENC interface
previously had "dss_54m_fck" as it's clock which couldn't be autoidled, and
hence the OCPIF_SWSUP_IDLE flag was needed.
Remove the OCPIF_SWSUP_IDLE flag from VENC interfaces as it's clock is
now "dss_ick". This allows the PRCM hardware to autoidle the VENC
interface clocks when they are not active, rather than relying on the
software to do it, which can keep the interface clocks active
unnecessarily.

wait for reset status"
This reverts commit f9a2f9c3fa76eec55928e8e06f3094c8f01df7cb. This
commit caused a regression in the I2C hwmod reset on OMAP2/3/4,
logging messages similar to these during boot:
[ 0.200378] omap_hwmod: i2c1: softreset failed (waited 10000 usec)
[ 0.222076] omap_hwmod: i2c2: softreset failed (waited 10000 usec)
While the original patch was intended to fix some reset-related timing
issues, it's believed that these problems were actually fixed by
commit 2800852a079504f35f88e44faf5c9c96318c0cca ("ARM: OMAP2+: hwmod:
Restore sysc after a reset"):

Due to HW limitation, some IPs should not be accessed just after a
softreset. Since the current hwmod sequence is accessing the sysconfig
register just after the reset, it might lead to OCP bus error in
that case.
Add a new field in the sysconfig structure to specify a delay in usecs
needed after doing a softreset.
In the case of the ISS and FDIF modules, the L3 OCP port will be
disconnected upon a SW reset. That issue was confirmed with HW simulation
and an errata should be available soon. The HW recommendation to avoid
that is to wait for 100 OCP clk cycles, before accessing the IP.
Considering the worse case (OPP50), the L3 bus will run at 100 MHz,
so a 1 usec delay is needed. Add an x2 margin to be safe.
