It is pretty helpful to know already from dmesg that a certain
device is successfully registered, instead of having to browse
sysfs to see if it's actually there.

Using the core support makes this element available to in kernel users as

Adding MPU6500 in target list for this driver.

Description:
Source
Document: MPU-6500 Register Map and Descriptions Revision 2.1
Section 3: Register Map

This section describes difference in terms device programmability
between MPU6050 and MPU6500.
These are different registers, which differs between MPU6050 and
MPU6500.

Addr	Name
---------------------
1E 	LP_ACCEL_ODR
6C	PWR_MGMT_2
77	XA_OFFSET_H
78	XA_OFFSET_L
7A	YA_OFFSET_H
7B	YA_OFFSET_L
7D	ZA_OFFSET_H
7E	ZA_OFFSET_L

But the current MPU6050 driver doesn't use registers which are different
except PWR_MGMT_2. The difference is support of "LP_WAKE_CTRL" at bit6-7
in MPU6050 mode. In MPU6500 they are not defined.
In current mpu6050 driver, only values used for this register are for
standby mode for gyro and accelerometer.
In both case frequency of wakeups is set to default and not using
bit 6-7.

So this driver van as well support MPU6500. In addition MPU6500 can
run MPU6050 mode by changing device trim settings.

So changing config comments to allow MPU6500 to use this driver.
When the driver is enhanced to support more functions, i2c driver
data INV_MPU6500 or "WHO_AM_I" register can be used to add additional
functionality.

AK8963 and AK8975 use same register definitions, except the range
of X,Y,Z values. Added support of 8963 based on i2c_device_id.
Unfortunately there is no way to detect the type via registers,
both device registers return 0x48 as id of chipset.

The incorrect limit for the for_each_set_bit loop was noticed whilst fixing
this other case.  Note that as we only have 3 possible entries a the moment
and the value was set to 4, the bug would not have any effect currently.
It will bite fairly soon though, so best fix it now.
