Linux kernel source tree
ffb4b4ed3e
Changes in take2: - Additional patch to drop the accidentally added empty file. - Tidy up of a duplicate include. Two merges of other trees. 6.12-rc2: To pull in the move of unaligned.h from include/asm to include/linux This was to resolve issues in linux-next. pwm/duty_offset-for6.13-rc1@ PWM infrastructure that is use di the AD7625 ADC driver. New device support ================== adi,ad7173 - Add support for the AD4113 8 channel ADC. adi,ad7606 - Add support for the AD7606C-16 and AD7606C-18 which have higher precision and support bipolar and differential channels. A lot of driver rework was needed to add the additional flexibility needed to support these parts. adi,ad7625 - New driver supporting AD7625, AD7626, AD7960 and AD7961 LVDS connected ADCs. Interface uses a combination of a PWM control and an IIO backend (currently a custom FPGA IP). adi,ad8460 - New driver for the ad8460 Waveform DAC. This high speed device is driven by a custom IP via a DMAEngine buffer. bosch,bmi270 - New driver for this 6-axis IMU. A later patch adds SPI support. gehc,pmc-adc - New driver for this GE Healthcare ADC 16-channel 16 bit ADC. invensense,mpu6050 - Add support for IAM-20680HT and IAM-20680HP variants of the IAM-20680 IMU that have better specifications in various ways including larger FIFO sizes. vishay,vl6030 - Support the veml7700, a stripped down veml6030 ambient light sensor. - Support the veml6035 ambient light sensor. Features ======== liteon,ltr390 - Allow configuration of sampling frequency - Support suspend and resume - Add interrupt support including threshold events + control over event reporting persistence. st,vl53l0x - Add support for continuous mode via IIO buffer support and a dataready trigger. ti,tmp0006 - Add triggered buffer support using data ready interrupt. vishay,vl6030 - Add regulator control support. vishay,vl6070 - Add regulator control support. vishay,vl6180 - Allow configuration of waiting between continuous samples. - Use the interrupt, if available, for single shot captures - Support continuous mode via the IIO triggered buffer interfaces. Cleanups and minor fixes ======================== tools/event monitor - Free dev_dir_name. treewide - Introduce aligned_s64 type for timestamps to replace s64 __aligned(8). Initial use in a few drivers - many others to follow. - Use dev_get_platform_data() instead of open-coding the access. - InvenSense email address and maintainer updates to reflect move to the tdk domain after acquisition. - Switch platform drivers from remove_new() back to remove() now all rework this was enabling is done. - More use of device_for_each_child_node_scoped() to remove need for manual caling of fwnode_handle_put() in early exits from the loop. - Use IIO_MAP() macro to replace some open-coded versions. - Constify struct iio_map arrays. - Use irq_get_trigger_type(irq) rather than irqd_get_trigger_type(irq_get_irq_data(irq); core - unsigned to unsigned int. adi,ad3552r - Fix to low a limit on max SPI clock speed. No rush to upstream this one as the binding that uses the higher speed will merge via this tree once ready. adi,ad5770r - Use get_unaligned_le16() instead of open-coding. Note this caused a merge issue in linux-next as unaligned.h has moved. adi,ad7606 - Use read_avail() callback to handle the various _available attributes. - Wrap up all data related to channel scaling into a single structure as the use of this gets more complex for the -16 and -18 parts. adi,adf4371 - Use chip_info structures and spi_get_device_match_data() - Drop spi_set_drvdata() as unused. - Reduce scope of struct clock as only touched in probe(). - Use dev_err_probe() where appropriate. adi,axi-dac - Improve register naming to make field and register association clearer. - Fix a wrong register bit. amlogic,meson8-saradc - Allow the meson8-saradc to have the amlogic,hhi-sysctrl property. bosch,bmp280 - Use u8 for the DMA buffer to avoid implication of other types given it can contain be24 data. - Use unsigned types to store raw values to make it clear they cannot be negative. - Drop unnecessary check for errors after IIR filter update. - Support soft reset to get device to know state on driver load. - Use bulk reads to retrieve the humidity calibration data. dynaimage,al3010 - Make sure to powerdown device in error paths. invensense,icm42600 - Add missing i2c_device-id tables. kionix,kmx61 - Drop ACPI IDs that are not associated with valid ACPI vendor IDs and for which there is no evidence they are in use in real devices. liteon,ltrf261a - Document a bad compatible that we are supporting because it is in the wild in the Valve Steam Deck via ACPI PRP0001. maxim,max1363 - Use get_unaligned_be16() instead of open-coding. Note this caused a merge issue in linux-next as unaligned.h has moved. mediatek,mt6360 - Use get_unaligned_be16() instead of open-coding. Note this caused a merge issue in linux-next as unaligned.h has moved. microchip,pac1921 - Drop various unnecessary type casts that were suggested by Wconversion compiler warnings which we do not use in IIO. Remove them because they hurt readability in cases where it is clear not overflow can occur. rohm,rpr0521 - Use iio_poll_func_store_time() rather than open-coding a similar solution. semtech,sx9324 - Make sx_common_get_raw_register() local to the only code that uses it. - Drop unnecessary acpi.h include. st,vl53l0x - Check the part ID register and print an info message if it is not what is expected. vishay,veml6030 - Fix DT binding file name to include vishay - Use regmap_set_bits() for case where all bits are set. - Use dev_err_probe() where appropriate. - Add missing delay after powering up in resume path. - Drop a processed accessor for the white channel as there is no public information to allow a specific scale to be established. - Use read_avail() to replace explicit custom _available attributes. vishay,veml6070 - Use guard() to allow early returns. - Add a devm callback to unregister the i2c device. - Use devm_iio_device_register() to simplify removal code. Various other minor improvements not called out explicitly. -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEEbilms4eEBlKRJoGxVIU0mcT0FogFAmcSmmQRHGppYzIzQGtl cm5lbC5vcmcACgkQVIU0mcT0FojNOg/6A9KP3u2rhirVMp2ZEb5z2thpJL5aTGc7 aHoPzw3TzFSyN2yBhW8kozQT1QhWp9NYcHfzRsadCrMSCnFFz9D337YNwwlBVUW8 swxc45LtdNCKbWj9GiR57hC/OpnYfcJ2d+Ljg9EoZdLugWbOqAeGXRvuXPP6NG9c dl5hCnF8baQxw5PVkcYs/By903ZcMvgE5s/s1ia6tp4GPUQhqwJ95BVkebg5ACua p22FmbEvO6zFk4TdP8VOR4OoAMbrLci/JI+jn+URWmujB569rwEaVoJmj1q3lQus yTI7Ooxo+tJeW9hf87gqmT7/6Knvmg4sfHRoJbPENqWCXx7aIGVi0du/N3jASJNt IcRsFyrb16Zo7l3dy9lYF68ulIllf/xFck/lTW8QHjfgZlMwpX5KjcSgEBS2GlYn wo5Za1ja0ZPw5SAYWANpC9iX5tskLIfmlhnoOnc0vHpvjdHAdvdmTivcJAiKcMOY DS6dTa0330IgIeEo7Phxp+Ml+cJ0qAdeV43VajJ3cesZIkygZY0t/yqZojecci6N 9YPMyzLe5NRcwcrhnw4laUau+7SW3vzaxFN2xVjLlelADIAk9LkdDE3dVUXq+Zhy 1cji9H/2YjzPbqaOI7AcQSSjb/u074luSqxObt80AXXXiFxDL5n65/2rsgSIVLp8 M5W1J4Jzl8E= =lBZ5 -----END PGP SIGNATURE----- Merge tag 'iio-for-6.13a-take2' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: IIO: 1st set of new device support, features and cleanup for 6.13 Changes in take2: - Additional patch to drop the accidentally added empty file. - Tidy up of a duplicate include.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
