As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree.

2023-07-15iio: adc: ina2xx: avoid NULL pointer dereference on OF device matchAlvin Šipraga1-3/+6
The affected lines were resulting in a NULL pointer dereference on our platform because the device tree contained the following list of compatible strings: power-sensor@40 { compatible = "ti,ina232", "ti,ina231"; ... }; Since the driver doesn't declare a compatible string "ti,ina232", the OF matching succeeds on "ti,ina231". But the I2C device ID info is populated via the first compatible string, cf. modalias population in of_i2c_get_board_info(). Since there is no "ina232" entry in the legacy I2C device ID table either, the struct i2c_device_id *id pointer in the probe function is NULL. Fix this by using the already populated type variable instead, which points to the proper driver data. Since the name is also wanted, add a generic one to the ina2xx_config table.

https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: 1st set of IIO new device support, features and cleanup for the 6.5 cycle. New device support - honeywell,mprls0025pa * New driver and dt-bindings for this series of pressure sensors. - invensense,mpu6050 * Add support for ICM 20600 IMU (ID, bindings and device data). - melexis,mlx90614 * Add support for mlx90615 Infra Red Thermometer after driver cleanup and refactoring to support the differences in this device. - renesas,x9250 * New driver and bindings for this quad potentiometer. - rockchip,saradc * Add support for RK3588. Also included is a bunch of refactoring and cleanup for that driver. - rohm,bu27008 * New driver bindings etc for this 5 photodiode color sensor. - st,lsm9ds0/st,st-sensors * ID added for LSM303D accelerometer and magnetometer including ACPI binding. - ti,opt4001 * New driver and bindings for this ambient light sensor. Features - core * Introduce iio_validate_own_trigger() for cases where a driver can only consumer a trigger it registered (detected via same parent device). Use it in the kionix,kx022a driver and new rohm,by27008 driver. - dynaimage,al3320a * ACPI binding CALS0001 seen on Lenovo Yoga Table 2 devices. - kionix,kx002a * Enable asynchronous probe. - rohm,bu27034 * Enable asynchronous probe. - ti,tmp006 * Explicit support for DT including binding documentation. Cleanups, minor fixes and misc improvements. - treewide * Switch I2C drivers from probe_new() back to probe() - part of the long process of getting rid of a parameter from probe() * Various whitespace and typo fixes not otherwise called out. - core * industrialio-buffer,Style cleanup. * Add documentation to extend_name field of struct iio_chan_spec to direct people using it towards the label infrastructure instead. extend_name was a design mistake a long time back so directly people away from it may be useful. - adi,ad7606 * Add HAS_IOPORT dependency to prepare for some Kconfig changes. - bosch,bma400 * Drop pointless print of ret in a dev_err_probe() message. - invensense,icm42600 * Rework timestamp handling to reduce jitter. - mediatek,mt7986-auxdac * Add DT binding for this part. - qcom,spmi-vadc * Allow for 1/16th prescaling used on a few devices. * Various changes to channel labeling and naming, including dropping use of fwnode_name which generates odd channel names. Small ABI change as a result, but not thought to be a problem for users of this platform. - st,lsm6dsx * dt-binding: Use common schema for mount-matrix via a reference. - st,stm32 * Add a debug print for when legacy channel config is used. - ti,palmas-adc * Drop unused i2c.h include. * tag 'iio-for-6.5a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (59 commits) dt-bindings: iio: rockchip: Fix 'oneOf' condition failed warning dt-bindings: iio: afe: voltage-divider: Spelling s/curcuit/circuit/ dt-bindings: iio: adc: Add rockchip,rk3588-saradc string iio: adc: rockchip_saradc: Use dev_err_probe iio: adc: rockchip_saradc: Match alignment with open parenthesis iio: adc: rockchip_saradc: Use of_device_get_match_data iio: adc: rockchip_saradc: Make use of devm_clk_get_enabled iio: adc: rockchip_saradc: Add support for RK3588 iio: adc: rockchip_saradc: Add callback functions iio: temperature: tmp006: Add OF device matching support dt-bindings: iio: temperature: Add support for tmp006 staging: iio: Switch i2c drivers back to use .probe() iio: amplifiers: ad8366 Fix whitespace issue iio: imu: inv_icm42600: avoid frequent timestamp jitter MAINTAINERS: Add ROHM BU27008 iio: light: ROHM BU27008 color sensor iio: kx022a: Use new iio_validate_own_trigger() iio: trigger: Add simple trigger_validation helper dt-bindings: iio: light: ROHM BU27008 iio: mlx90614: Add MLX90615 support ...
2023-06-10meson saradc: fix clock divider mask lengthGeorge Stark1-1/+1
According to the datasheets of supported meson SoCs length of ADC_CLK_DIV field is 6-bit. Although all supported SoCs have the register with that field documented later SoCs use external clock rather than ADC internal clock so this patch affects only meson8 family (S8* SoCs).
