[ 0.154998] (null): Unsupported NAND ECC scheme selected

Currently we're attempting to use a static value for the
voltctrl register that only works for controlling the PMIC
over I2C4. For using sys_off_mode signaling, we need to update
update clksetup, voltsetup1, voltsetup2 and voltctrl registers
dynamically depending on the idle state.
So let's fix this by configuring things for I2C4 controlled idle
and sys_off_mode pin controlled idle, and then write the
configured register values depending on the idle state. This
is similar what N900 kernel is doing too.

Commit c589eb3869a8 (ARM: OMAP3: VC: calculate ramp times)
started using regulator slew rates for calculating the idle
mode start-up times. This works fine for I2C4 controlled
regulator scaling as the regulators are never completely
turned off.
For sys_off_mode pin controlled PMIC scripts, the slew rate
based calculations won't work at all as the regulators are
completely turned off and the start-up time is much longer.
This means currently omap3_set_off_timings currently has
zero chance of working on any real hardare. The current code
is broken in at least the following ways:
1. It attempts to use the default ULONG_MAX value for the
oscillator start-up value as we're currently never
initializing the start-up value.
2. It relies on a magic number potentially set by the
bootloader for volsetup2 register.
3. If no magic value is passed, it attempts to calculate
voltsetup2 register based on the regulator slew rate.
This won't work as there is roughly at least five
times the delay needed for turning on vdd1 and vdd2
regulators.
4. It does duplicate register write to OMAP3_PRM_VOLTOFFSET
5. It duplicates the code for omap_usec_to_32k unnecessarily
6. It initialized global registers twice, once for each channel
Let's just remove the broken code and call omap3_set_i2c_timings
directly, we're better off with this function doing nothing until
it's fixed. And otherwise further fixes to omap3_set_off_timings
will be unreadable.
And let's get rid of omap3_set_clksetup as that's not needed
for off-idle controlled by I2C4 as in that case the oscillator
is never shut down.

While debugging legacy mode vs device tree booted PM regressions,
I noticed that omap3 is not toggling sys_clkreq and sys_off_mode
pins like it should.
The sys_clkreq and sys_off_mode pins are not toggling because of
the following issues:
1. The default polarity for the sys_off_mode pin is wrong.
OFFMODE_POL needs to be cleared for sys_off_mode to go down when
hitting off-idle, while CLKREQ_POL needs to be set so sys_clkreq
goes down when hitting retention.
2. The values for voltctrl register need to be updated dynamically.
We need to set either the retention idle bits, or off idle bits
in the voltctrl register depending the idle mode we're targeting
to hit.
Let's fix these two issues as otherwise the system will just
hang if any twl4030 PMIC idle scripts are loaded. The only case
where the system does not hang is if only retention idle over I2C4
is configured by the bootloader.
Note that even without the twl4030 PMIC scripts, these fixes will
do the proper signaling of sys_clkreq and sys_off_mode pins, so
the fixes are needed to fix monitoring of PM states with LEDs or
an oscilloscope.

On my DRA7 system, when the kernel is built in Thumb-2 mode, the secondary CPU
(Cortex A15) fails to come up causing SMP boot on second CPU to timeout. This
seems to be because the CPU is in ARM mode once the ROM hands over control to
the kernel. Switch to Thumb-2 mode if required once the kernel is control of
secondary CPU. On OMAP4 on the other hand, it appears to be in Thumb-2 mode on
entry so this is not required and SMP boot works as is.
Also corrected a spurious '+' and updated copyright information.

At least the smc91x driver expects the device to be at 0x300
offset from bus base address. This does not work currently
for GPMC when booted in device tree mode as it attempts to
remap the the allocated GPMC partition to the address
configured by the device tree plus the device offset.
Note that this works just fine when booted with legacy mode.
Let's fix the issue by just ignoring any device specific
offset while remapping. And let's make sure the remap
address confirms to the GPMC 16MB minimum granularity
as listed in the TRM for GPMC_CONFIG7 BASEADDRESS bits.
Otherwise we can get something like this:

I noticed a regression where the omap sys_clkreq signal will never
trigger for omap3 when booted with device tree while it triggers
when booted in legacy mode. This means voltage scaling does not
do anything when booted with device tree.
Turns out the reason is we fail to initialize the SmartReflex
enable bit in twl4030 with the following error:
twl: not initialized
And that happens because we are wrongly tinkering with the twl4030
registers in arch/arm/mach-omap2/omap_twl.c before the driver is
initialized. Looking at the the SmartReflex bit enable code in
omap_twl.c, we need to always set it.
So let's fix the issue by always enabling the twl4030 SmartReflex
bit in the drivers/mfd/twl-core.c probe, and drop the related
code in omap_twl.c.
Note that we still have some twl4030 tinkering left in omap_twl.c
for the twl6030 case, but that's a different patch.

However v1 apparently seemed to have been pulled in by mistake

Given of_find_property() does return NULL when the node passed is
NULL, it did not introduce any functional issues as such, just the
fact that the second if check was executed unnecessarily.

There is a solitary write to this register every wakeup from off-mode,
which isn't doing anything, so remove it.
Also note that modifying this register trashes any attempted
voltage scaling configuration and the change probably should
never have gotten merged in the first place.

This time a few more updates queued up.
* Rework VT-d code to support ACPI devices
* Improvements for memory and PCI hotplug support
in the VT-d driver
* Device-tree support for OMAP IOMMU
* Convert OMAP IOMMU to use devm_* interfaces
* Fixed PASID support for AMD IOMMU
* Other random cleanups and fixes for OMAP, ARM-SMMU
and SHMOBILE IOMMU
Most of the changes are in the VT-d driver because some rework was
necessary for better hotplug and ACPI device support.
