iio: imu: inv_mpu6050: read the full fifo when processing data When processing data read the full fifo data in 1 time. If there are several samples in the FIFO, it means we are experiencing system delay. In this case, it is better to read all data with 1 bus access than to add additional latency by doing several ones. This requires to use a bigger buffer depending on chip FIFO size and do an additional local data copy before sending. But the cost is minimal and behavior is still better like this under system heavy load.

iio:imu:inv_mpu6050 Fix dma and ts alignment and data leak issues. This case is a bit different to the rest of the series. The driver was doing a regmap_bulk_read into a buffer that wasn't dma safe as it was on the stack with no guarantee of it being in a cacheline on it's own. Fixing that also dealt with the data leak and alignment issues that Lars-Peter pointed out. Also removed some unaligned handling as we are now aligned. Fixes tag is for the dma safe buffer issue. Potentially we would need to backport timestamp alignment futher but that is a totally different patch.

iio: imu: mpu6050: Fix FIFO layout for ICM20602 The MPU6050 driver has recently gained support for the ICM20602 IMU, which is very similar to MPU6xxx. However, the ICM20602's FIFO data specifically includes temperature readings, which were not present on MPU6xxx parts. As a result, the driver will under-read the ICM20602's FIFO register, causing the same (partial) sample to be returned for all reads, until the FIFO overflows. Fix this by adding a table of scan elements specifically for the ICM20602, which takes the extra temperature data into consideration. While we're at it, fix the temperature offset and scaling on ICM20602, since it uses different scale/offset constants than the rest of the MPU6xxx devices.

iio:imu: inv_mpu6050: support more interrupt types Currently, we support only rising edge interrupts, and in fact we assume that the interrupt we're given is rising edge (and things won't work if it's not). However, the device supports rising edge, falling edge, level low, and level high interrupts. Empirically, on my system, switching to level interrupts has fixed a problem I had with significant (~40%) interrupt loss with edge interrupts. This issue is likely related to the SoC I'm using (Allwinner H3), but being able to switch the interrupt type is still a very useful workaround. I tested this with each interrupt type and verified correct behavior in a logic analyzer. Add support for these interrupt types while also eliminating the error case of the device tree and driver using different interrupt types.

iio:imu:mpu6050 add explicit mpu9250 support The mpu9250 is a SIP containing an mpu6500 and an ak8975. If this was all there was too it there would be no need for explicit handling in the driver. Arguably the bindings would also only reflect the presence of an mpu6500 with the ak8975 hanging off it, as the kernel doesn't care that they are in one package. However, the WHOAMI value changes as well so best to add explicit support. Signed-off-by: Jonathan Cameron <jic23@kernel.org>

iio: imu: inv_mpu6050: Create mux clients for ACPI This is a follow up patches after adding i2c mux adapter for bypass mode. Potentially many different types of sensor can be attached to INVMPU6XXX device, which can be connected to main cpu i2c bus in bypass mode. Why do we need this? The system ACPI table entry will consist of only one device for INV6XXX, assuming that this driver will handle all connected sensors. That is not true for the Linux driver. There are bunch of IIO drivers for each sensors, hence we created a mux on this device. So to load these additional drivers, we need to create i2c devices for them in this driver using this mux adapter. There are multiple options: 1. Use the auto detect feature, this needs a new i2c class for the adapter as the existing HWMON class is not acceptable. Also the autodetect has overhead of executing detect method for each matching class of adapters. This is a simple implementation. This option was previously submitted with not a happy feedback. 2. Option is use ACPI magic and parse the configuration data. What we need to create a i2c device at a minimum is address and a name. Address can be obtained for secondary device in more or less in a standard way from using _CRS element. But there is no name. To get name we need to process proprietary vendor data. Not having name is not fun, as you have to create device using the device name of INVN6XXXX, respecting driver duplicate name space restriction. Also each client driver needs to have this name in the id table. Since multiple driver can be loaded, the driver should be able to detect its presence and gracefully exit for the other client driver to take it over. So we use two step process: - Use DMI to id platform and parse propritery data. This is not uncommon for many x86 platform specific driver. We will get both name and address. The change created necessary infrastructure to add more properitery vendor data parsing. - If DMI match fails, then create device on INV6XXX-client (we can't create with same name as INV6XXX as it will cause duplicate name and driver model will reject.) With this each client sensor driver which needs to get attached via INV6XXXX, need this name in the id table and detect the physical presence of sensor in probe and exit if not found.

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>

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.
