Subject: [PATCH v5 0/2] iio: imu: smi240: add bosch smi240 driver
Date: Wed, 4 Sep 2024 16:05:04 +0200 [thread overview]
Message-ID: <20240904140506.4741-1-Jianping.Shen@de.bosch.com> (raw)
From: Shen Jianping <Jianping.Shen@de.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
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
