With the new parameters, I2C can now be put to high speed mode for
better performance.

VC code now provides a table of pre-calculated I2C setup parameters,
which will be used based on the capacitance value calculated for the I2C
trace on the PCB. A default trace length of 6.3cm is used unless board
defines its own value during init. The parameters set will be the I2C
internal pull setup and the I2C timing parameters for high speed use
mode. Full speed mode is not supported as of now.

This is no longer needed as the ramp times are calculated from
voltage deltas + slew rates.

As vddmin / vddmax voltages for the pmic only describe the pmic
capabilities now, change the voltages to be according to spec.
TWL data manuals give following values:
TWL4030 (SWCS019L) : VDD1: 600mV ... 1450mV, VDD2: 600mV ... 1500mV
TWL5030 (SWCS030E) : VDD1: 600mV ... 1450mV, VDD2: 600mV ... 1500mV
TWL6030 (SWCS045A) : 0V ... 2100mV

This contains startup and shutdown times for the oscillator. By default
use ULONG_MAX. Oscillator setup is used for calculating and setting up
latencies for sleep modes that disable oscillator.

OMAP4 VC code now uses voltage deltas + slew rates for calculating
actual ramp times for voltage changes. Both retention / sleep +
off mode voltage ramp times are setup at the same time during
initialization.

OMAP4 has two VOLTSETUP registers. One is controlling retention and
sleep voltage setup times, the other one off mode setup times. Both
of these need to be setup for stable behavior of the device.
The code setting up the new register will be added in the next
patch.

OMAP3 VC code now uses voltage deltas + slew rates for calculating actual
ramp times for voltage changes. Previously a static value was used.
Two calculation methods are provided: i2c_timings and off_timings.
I2C timings are used during retention or off mode transition which
is initiated over I2C, and OFF timings are used if PMIC signal
(nsleep) is used to control all the off mode voltages at the same time.

These new structs will hold the sleep voltage levels (omap_vc_params)
and voltage processor min / max voltages (omap_vp_params.) Previously
these were part of the PMIC struct, but they do not really belong there,
as they are OMAP chip specific, not PMIC specific parameters. voltdm
code is also changed to use the new structs.

These are now called vddmin and vddmax, as these fields will be used
globally for selecting voltage ranges for a pmic channel, and not
only for voltage processor.

Every PMIC has it's own eccentricities, For example, one of the
PMIC has MSB set to 1 for a specific function - voltage enable!
using an hardcoded value specific for TWL when copied over to
such an implementation causes the system to crash as the MSB bit
was 0 and the voltage got disabled!.
Instead we use actual values and depend on the convertion routines
to abstract out the eccentricities of each PMIC.
With this, we can now move the voltages to a common location in
voltage.h as they are no longer dependent on PMICs and expect the
PMIC's conversion routines to set a cap if the voltage is out of
reach for the PMIC.

When sending data into a tcp socket in repair state we should check
for the amount of data being 0 explicitly. Otherwise we'll have an skb
with seq == end_seq in rcv queue, but tcp doesn't expect this to happen
(in particular a warn_on in tcp_recvmsg shoots).

vmxnet3 has a 16Kbytes limit per tx descriptor, that happened to work
as long as we provided PAGE_SIZE fragments.
Our stack can now build larger fragments, so we need to split them to
the 16kbytes boundary.

When creating an L2TPv3 Ethernet session, if register_netdev() should fail for
any reason (for example, automatic naming for "l2tpeth%d" interfaces hits the
32k-interface limit), the netdev is freed in the error path. However, the
l2tp_eth_sess structure's dev pointer is left uncleared, and this results in
l2tp_eth_delete() then attempting to unregister the same netdev later in the
session teardown. This results in an oops.
To avoid this, clear the session dev pointer in the error path.

There are systems where video module known to work fine regardless
of broken _DOD and ignoring returned value here doesn't cause
any issues later. This should fix brightness controls on some laptops.
