N900 audio recording needs that codec provides bias voltage for integrated
digital microphone and headset microphone depending which one is used.
Digital microphone uses 2 V bias and it comes from the codec A part. Codec
B part drives the headset microphone bias and that is set to 2.5 V.

Pull ARM DT updates from Olof Johansson:
"As always, this tends to be one of our bigger branches. There are
lots of updates this release, but not that many jumps out as something
that needs more detailed coverage. Some of the highlights are:
- DTs for the new Annapurna Labs Alpine platform
- more graphics DT pieces falling into place on Exynos, bridges,
clocks.
- plenty of DT updates for Qualcomm platforms for various IP blocks
- some churn on Tegra due to switch-over to tool-generated pinctrl
data
- misc fixes and updates for Atmel at91 platforms
- various DT updates to add IP block support on Broadcom's Cygnus
platforms
- more updates for Renesas platforms as DT support is added for
various IP blocks (IPMMU, display, audio, etc)"

This patch moves content of file omap34xx-hs.dtsi into omap3-n900.dts and enable
omap sham support (omap HW support for SHA + MD5). After testing both omap hwmod
and omap-sham.ko drivers it looks like signed Nokia X-Loader enable L3 firewall
for omap sham. There is no kernel crash with both official bootloader and crypto

Offset for smc91x must be zero otherwise smc91x linux kernel driver does not
detect smc91x ethernet hardware in qemu N900 machine.
The 0x300 offset was used to supress a warning the smsc911x
driver produces about non-standard offset as 0x300 seems to
be the EEPROM default. As only three address lines are
connected both 0 and 0x300 will work just fine with 0 being
correct. The warning about the non-standard offset can be
fixed by writing to EEPROM as that's needed in any case to
set the MAC address.

With legacy boot i2c buses on Nokia N900 are numbered i2c1, i2c2 and i2c3.
Commit 20b80942ef4e ("ARM: dts: OMAP3+: Add i2c aliases") fixed the
numbering with DT boot, but introduced a regression on N900 - aliases
become i2c0, i2c1 and i2c2. Fix that by providing the correct aliases in
the board dts.

Revert "ARM: dts: Disable smc91x on n900 until bootloader
dependency is removed". We've now fixed the issues that
caused problems with uninitialized hardware depending on
the bootloader version. Mostly things got fixed with
the following commits:
9a894953a97b ("ARM: dts: Fix bootloader version dependencies by muxing n900 smc91x pins")
7d2911c43815 ("net: smc91x: Fix gpios for device tree based booting")
Note that this only affects the early development boards
with Ethernet that we still have in a few automated boot
test systems. And it's also available supposedly in some
versions of qemu.

With legacy booting, the platform init code was taking care of
the configuring of GPIOs. With device tree based booting, things
may or may not work depending what bootloader has configured or
if the legacy platform code gets called.
Let's add support for the pwrdn and reset GPIOs to the smc91x
driver to fix the issues of smc91x not working properly when
booted in device tree mode.
And let's change n900 to use these settings as some versions
of the bootloader do not configure things properly causing
errors.

The GPMC binding is obviously very confusing as the values
are all over the place. People seem to confuse the GPMC partition
size for the chip select, and the device IO size within the GPMC
partition easily.
The ranges entry contains the GPMC partition size. And the
reg entry contains the size of the IO registers of the
device connected to the GPMC.
Let's fix the issue according to the following table:
Device GPMC partition size Device IO size
connected in the ranges entry in the reg entry
NAND 0x01000000 (16MB) 4
16550 0x01000000 (16MB) 8

As we have support for this in board-rx51-peripherals.c, let's
add it to the .dts files too.
Note that the reset GPIO will eventually go to the driver.
For now let's just pull it down and skip any further reset
in case the bootloader has configured the MAC address so
NFSroot works.
Also note that after 3430-sdp are using proper GPMC timings
we can remove the tests for smsc,lan91c94 in gpmc.c.

The quite-recently-added analog-tv-connector bindings say that the
compatible string for composite video connector is
"composite-connector". That string is also used in the omap3-n900.dts
file. However, the connector driver uses "composite-video-connector", so
this has never worked.
While changing the driver's compatible string to "composite-connector"
would be safer, as published DT bindings should not be changed, I'd
rather fix the bindings in this case for two reasons:
* composite-connector is a bit too generic name, as it doesn't even hint
at video.
* it's clear that this has never worked, which means no one has used
those bindings, which should make it safe to change this.

to cut off resources during deeper idle states to save power.
This however caused regression for n900 display power that needed the
PMIC configuration to be disabled with commit d937678ab625 (ARM: dts:
Revert enabling of twl configuration for n900).
Turns out the root cause of the problem is that we must use
TWL4030_RESCONFIG_UNDEF instead of DEV_GRP_NULL to avoid disabling
regulators that may have been enabled before the init function
for twl4030-power.c runs. With TWL4030_RESCONFIG_UNDEF we let the
regulator framework control the regulators like it should. Here we
need to only configure the sys_clken and sys_off_mode triggers for
the regulators that cannot be done by the regulator framework as
it's not running at that point.
This allows us to enable the PMIC configuration for n900.

Commit 9188883fd66e9 (ARM: dts: Enable twl4030 off-idle configuration
for selected omaps) allowed n900 to cut off core voltages during
off-idle. This however caused a regression where twl regulator
vaux1 was not getting enabled for the LCD panel as we are not
requesting it for the panel.
Turns out quite a few devices on n900 are using vaux1, and we need
to either stop idling it, or add proper regulator_get calls for all
users. But until we have a proper solution implemented and tested,
let's just disable the twl off-idle configuration for now for n900.

N900 now seems to shut down the external oscillator when hitting
off-idle.
And Beagle XM seems to have OSC_EN pin connected to allow shutting
down the oscillator looking at the schematics. The oscillator
output is cut off in off-idle and you can monitor it from R56 on
the bottom side of the board near the power jack. Note that for
beagle we need to also enable the UART wake-up event, the others
have that enabled in earlier patches.
OMAP37XX EVM (TMDSEVM3730) does not seem to have twl4030 clken
pin connected, so there is no point trying to enable shutting
down of the oscillator on it for the extra latency it adds.

On N900 there are nice LEDs that show the state of the
sys_clkreq and sys_off_mode pins.
These LEDs go low when the system enters deeper idle
states. The left LED shows the state of the sys_clkreq
pin, and goes off during retention idle. The right LED
shows the state of sys_off_mode pin and both go off
during off idle.
As N900 is a battery operated device, these LEDs should
be off most of the time. So let's enable them by default
so we can make sure the system is mostly idle.
This allows the maintainers to also immediately test
patches for PM regressions by looking at the LEDs,
which certainly makes my life easier.
The LED can naturally be disabled during runtime with:
# echo none > /sys/class/leds/debug::sleep/trigger
Note that we don't currently have support for omap3
errata 1.158 that remuxes GPIO pins to INPUT_PULLUP |
MUX_MODE7 for the duration of idle. This means that the
GPIO pins set high will go down during off idle. In this
case it does not matter as the sys_off_mode goes down
too, but there's still a slim chance of false off idle
LED signals. If in doubt, false LED signals can be
verified by the sys_off_mode or vdd_core values.
Also note that to allow the UARTs to autoidle, the
following needs to be run on N900 to enable off idle:
#!/bin/sh
uarts=$(find /sys/class/tty/ttyO*/device/power/ -type d)
for uart in $uarts; do
echo 3000 > $uart/autosuspend_delay_ms
done
uarts=$(find /sys/class/tty/ttyO*/power/ -type d)
for uart in $uarts; do
echo enabled > $uart/wakeup
echo auto > $uart/control
done
echo 1 > /sys/kernel/debug/pm_debug/enable_off_mode
For retention idle, change the above to set 0 to
enable_off_mode.
Also note that without the twl4030 PM scripts the actual
voltage scaling won't happen for off idle so we only get
voltage scaling over I2C4 for retention idle. I'll do
some device tree patches for those also a bit later on.

We've had deeper idle states working on omaps for few years now,
but only in the legacy mode. When booted with device tree, the
wake-up events did not have a chance to work until commit
3e6cee1786a1 (pinctrl: single: Add support for wake-up interrupts)
that recently got merged. In addition to that we also needed commit
79d9701559a9 (of/irq: create interrupts-extended property) and
9ec36cafe43b (of/irq: do irq resolution in platform_get_irq) that
are now also merged.
So let's fix the wake-up events for some selected omaps so devices
booted in device tree mode won't just hang if deeper power states
are enabled, and so systems can wake up from suspend to the serial
port event.
Note that there's no longer need to specify the wake-up bit in
the pinctrl settings, the request_irq on the wake-up pin takes
care of that.

It seems that mostly vaux3 is used, and only some earlier revisions
used vmmc2. This has been tested to work on devices where the
