isl29028_chip_init() contains the device driver defaults and
two I2C calls that detect the presence of the chip. This patch
moves these into isl29028_probe() so that this function can
be used by the power management runtinme in a followup patch. This
patch also renames isl29028_chip_init() to
isl29028_chip_init_and_power_on().

There are two callers to the function isl29028_set_als_ir_mode() and
both instances use a nested if statement to only change the chip state
if it is not in the proper mode. This patch moves this check into the
isl29028_set_als_ir_mode() function to remove the nested if
statements.

At the end of function ad7150_write_event_config(), directly returns 0.
As a result, the errors will be ignored by the callers. It may be better
to return variable "ret".

In function cm3232_reg_init(), it returns 0 even if the last call to
i2c_smbus_write_byte_data() returns a negative value (indicates error).
As a result, the return value may be inconsistent with the execution
status, and the caller of cm3232_reg_init() will not be able to detect
the error. This patch fixes the bug.

Added timestamp channel. With this change, each sample has a timestamp.
This timestamp can be from the sensor hub when present or local kernel
timestamp. HID sensors can send timestamp with input data using usage id
HID_USAGE_SENSOR_TIME_TIMESTAMP. This timestamp value is converted to
nano seconds before pushing this sample to the iio core.

msleep(1~20) may not do what the caller intends, and will often sleep longer.
(~20 ms actual sleep for any value given in the 1~20ms range)
This is not the desired behaviour for many cases like device resume time,
device suspend time, device enable time, data reading time, etc.
Thus, change msleep to usleep_range for precise wakeups.

This is a feature for the client and server to use
obd_connect_flags2 to communicate future feature flags. The
client should set this flag whenever any flags in that field
are requested, and the server should mask unsupported features
from this field (assuming it understands OBD_CONNECT_FLAGS2).
When checking if an OBD_CONNECT2_xxxx feature is supported,
the client/server needs to firstly check if OBD_CONNECT_FLAGS2
is supported, since this field is also beyond the end of the
old obd_connect_data.

Land the connection flags to upstream client earlier for reserving
the slot to avoid potential conflict with others.
