* iio: imu: inv_mpu6050: Add i2c mux for by passSrinivas Pandruvada2014-12-123-6/+116
| | | | | | | | | | | | | | | | | 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>

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Users of this functionality to follow. 5) For iio use the device tree node name to provide the hwmon name attribute if available. Removal and moves out of staging 1) Drop the adt7410 driver from IIO now that there is a hmwon driver with equivalent support. This device is very much targeted at hardware monitoring so hwmon is a more appropriate host for the driver. 2) Move iio_hwmon driver to drivers/hwmon. Cleanups 1) Minor cleanup in ST common library. 2) Large set of patches to break the info_mask element which previously used odd and even bits to specify if a channel attribute was either shared across similar channels or specific to only one. Now we have two bitmaps, one for those parameters that are specific to this channel and one for those shared by all channels with the same type as this one. This has no effect on the userspace abi. It simplifies the core code and provides more space for new channel parameters. It has been on the todo list for a long time! Conflicts: drivers/iio/dac/ad5064.c
