      iio: st_sensors: move regulator retrieveal to core · ea7e586b
      由 Linus Walleij 提交于 
      Currently the pressure sensor has code to retrieve and enable two
regulators for Vdd and Vdd IO, but actually these voltage inputs
are found on all of these ST sensors, so move the regulator
handling to the core and make sure all the ST sensors call these
functions on probe() and remove() to enable/disable power.

Here also mover over to obtaining the regulator from the *parent*
device of the IIO device, as the IIO device is created on-the-fly
in this very subsystem it very unlikely evert have any regulators
attached to it whatsoever. It is much more likely that the parent
is a platform device, possibly instantiated from a device tree,
which in turn have Vdd and Vdd IO supplied assigned to it.

      iio: st_sensors: announce registered sensors · 4f544ced
      由 Linus Walleij 提交于 
      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.

      iio: imu: inv_mpu6050: Add compatibity with MPU6500 · 6f174fd3
      由 Srinivas Pandruvada 提交于 
      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.
