iio: imu: inv_mpu6050: Add i2c mux for by pass This chip allows some limited number of sensors connected to it as slaves, which can be directly accessed by register interface of this driver.But the current upstream driver doesn't support such mode. To attach such slaves to main processor i2c bus, chip has to be set up in bypass mode. This change adds i2c mux, which will enable/disable this mode for transaction to/from such slave devices. This was discussed for a while in mailing list, this was the outcome: Reference: http://www.spinics.net/lists/linux-iio/msg12126.html http://comments.gmane.org/gmane.linux.kernel.iio/11470 Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Reviewed-by: Wolfram Sang <wsa@the-dreams.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

This driver supports the Invensense MPU6050 devices.
iio: imu: inv_mpu6050: Add compatibity with MPU6500 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.

This driver can also support MPU6500 in MPU6050 compatibility mode
and also in MPU6500 mode with some limitations.

It is a gyroscope/accelerometer combo device.
This driver can be built as a module. The module will be called
inv-mpu6050.
