Jonathan writes:
Third set of IIO new device support cleanups and fixes for the 5.5 cycle.
New device support
* ad5446
- Support the ad5600 DAC (id only needed).
* ad7292 ADC DAC etc
- New driver plus dt-bindings.
* veml6030 ambient light sensor
- New driver plus dt-bindings and sysfs docs.
Features
* mpu6050
- Explicit VDD control.
* stm32-adc
- Allow limiting of max clock frequency from devicetree to ensure it's
suitable for external circuitry.
yaml binding conversions
* ltc1660
* mcp3911
Fixes
* adis16480
- Fix wrong scale factors.
- Fix debugfs reg access by providing the callback.
* cros_ec_baro
- Fixing missing mask entry to make available sample frequencies visible
in sysfs.
* st_lsm6dsx
- Explicitly handle different ODR table sizes.
- Handle restrictions between slave ODR and accel ODR when
both are enabled.
- Allow ODR to be expressed more accurately by using miliHz.
* tools
- Fix an issue with parallel builds.
Cleanups and warning fixes
* adis16136, adis16400, adis16460, adis-lib
- Change some checks on return values to be for 0 rather than strictly
negative. Avoids some fiddly issues with the compiler concluding some
variables are initialized due to a mixture of error checks.
- Assign values only on success of 'read' operations - avoiding any
chance the compiler will falsly suggest they might be used uninitialized.
- Whitespace and simlar cleanups.
* aspeed adc
- devm_platfom_ioremap_resource to reduce boilerplate.
* bcm-iproc-adc
- Stray semicolon removal.
* cc10001
- devm_platfom_ioremap_resource to reduce boilerplate.
* dln2-adc
- Reorganise the buffered mode setup and tear down. Part of moving towards
being able to refactor this area of the IIO core.
* hdc100x
- Reorganise the buffered mode setup and tear down.
* ingenic-adc
- devm_platfom_ioremap_resource to reduce boilerplate.
* lpc18xx-adc
- devm_platfom_ioremap_resource to reduce boilerplate.
* lpc18xx-dac
- devm_platfom_ioremap_resource to reduce boilerplate.
* mt6577
- devm_platfom_ioremap_resource to reduce boilerplate.
* npcm
- devm_platfom_ioremap_resource to reduce boilerplate.
* rcar-gyroadc
- devm_platfom_ioremap_resource to reduce boilerplate.
* spear-adc
- devm_platfom_ioremap_resource to reduce boilerplate.
* vf610-adc
- devm_platfom_ioremap_resource to reduce boilerplate.
* vf610-dac
- devm_platfom_ioremap_resource to reduce boilerplate.
