Subject: [PATCH v7 0/2] iio: imu: smi240: add bosch smi240 driver

From: Shen Jianping <Jianping.Shen@...bosch.com>

Add the iio driver for bosch imu smi240. The smi240 is a combined
three axis angular rate and three axis acceleration sensor module
with a measurement range of +/-300°/s and up to 16g. This driver
provides raw data access for each axis through sysfs, and tiggered
buffer for continuous sampling. A synchronous acc and gyro sampling
can be triggered by setting the capture bit in spi read command.

dt-bindings: 
v1 -> v2
    - Add more detail in description
    - Add maintainer
    - Add vdd and vddio power supply
    - Use generic node name
    - Order the properties according to DTS coding style

v2 -> v3
    - Improve description
    - Improve supply definition
    - Make supply definition as required
    - Add supply definition in example

v3 -> v4
    - No changes

v4 -> v5
    - No changes

v5 -> v6
    - Fix checkpatch findings

v6 -> v7
    - No changes

imu driver:
v1 -> v2
    - Use regmap for register access
    - Redefine channel for each singel axis
    - Provide triggered buffer
    - Fix findings in Kconfig
    - Remove unimportant functions

v2 -> v3
    - Use enum für capture mode
    - Using spi default init value instead manual init 
    - remove duplicated module declaration
    - Fix code to avoid warning

v3 -> v4
    - Use DMA safe buffer
    - Use channel info instead of custom ABI
    - Fix other findings

v4 -> v5
    - Merge the implementation in one simple file
    - Add channel info for acc/gyro data channel
    - Fix other findings

v5 -> v6
    - Fix checkpatch findings
    - Fix review findings

v6 -> v7
    - Fix offset and scale
