2020-05-16iio: dac: ad5360: Replace indio_dev->mlock with own device lockSergiu Cuciurean
As part of the general cleanup of indio_dev->mlock, this change replaces it with a local lock on the device's state structure. This also changes some internal functions to pass the pointer to the state-struct vs a ref to indio_dev just to access the state-struct again.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Second set of new device support, cleanups and features for IIO in the 5.8 cycle Usual mixed back but with a few subsystem wide or device type wide cleanups. New device support * adis16475 - New driver supporting adis16470, adis16475, adis16477, adis16465, adis16467, adis16500, adis16505 and adis16507. Includes some rework of the adis library to simplify using it for this new driver. * ak8974 - Add support for Alps hscdt008a. ID only. Related patches add support for scale. * atlas-sensor - Add support for RTD-SM OEM temperature sensor. * cm32181 - Add support for CM3218 including support for SMBUS alert via ACPI resources. * ltc2632 - Add support for ltc2634-12/10/8 DACS including handling per device type numbers of channels. Major Features * cm32181 - ACPI bindings including parsing CPM0 and CPM1 custom ACPI tables. Includes minor tidy ups and fixes. * vcnl4000 - Add event support - Add buffered data capture support - Add control of sampling frequency Cleanups and minor fixes. * core - Trivial rework of iio_device_alloc to use an early return and improve readability. - Precursors to addition of multiple buffer support. So far minor refactoring. * subsystem wide - Use get_unaligned_be24 slightly improve readability over open coding it. * adis drivers - Use iio_get_debugfs_dentry access function. * bh1780, cm32181, cm3232, gp2ap02a00f, opt3001, st_uvis25, vl6180, dmard06, kxsd9 - Drop use of of_match_ptr to allow ACPI based probing via PRP0001. Part of clear out of this to avoid cut and paste into new drivers. * ad5592r, ad5593r - Fix typos * ad5933 - Use managed interfaces to automate error handling and remove. * ak8974 - Fix wrong number of 'real bits' for buffered data. - Refactor to pull measurement code out as separate function. bmp280 - Fix lack of clamp on range during data capture. * at91-sama5d2_adc - Handle unfinished conversions correctly. - Allow use of triggers other than it's own. - Reorganize buffer setup and tear down as part of long running subsystem wide rework. * ccs811 - Add DT binding docs and match table. - Support external reset and wakeup pins. * hid-sensors - Reorganize buffer setup and tear down as part of long running subsystem wide rework. * ltr501 - Constify some structs. * vcnl4000 - Fix an endian issue by using explicit byte swapped i2c accessors. * tag 'iio-for-5.8b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (74 commits) iio: light: ltr501: Constify structs staging: iio: ad5933: attach life-cycle of kfifo buffer to parent device and use managed calls throughout iio: bmp280: fix compensation of humidity iio: light: cm32181: Fix integartion time typo iio: light: cm32181: Add support for parsing CPM0 and CPM1 ACPI tables iio: light: cm32181: Make lux_per_bit and lux_per_bit_base_it runtime settings iio: light: cm32181: Use units of 1/100000th for calibscale and lux_per_bit iio: light: cm32181: Change reg_init to use a bitmap of which registers to init iio: light: cm32181: Handle CM3218 ACPI devices with 2 I2C resources iio: light: cm32181: Clean up the probe function a bit iio: light: cm32181: Add support for the CM3218 iio: light: cm32181: Add some extra register defines iio: light: cm32181: Add support for ACPI enumeration iio: light: cm32181: Switch to new style i2c-driver probe function iio: hid-sensors: move triggered buffer setup into hid_sensor_setup_trigger iio: vcnl4000: Add buffer support for VCNL4010/20. iio: vcnl4000: Add sampling frequency support for VCNL4010/20. iio: vcnl4000: Add event support for VCNL4010/20. iio: vcnl4000: Factorize data reading and writing. iio: vcnl4000: Fix i2c swapped word reading. ...

2020-01-18iio: dac: stm32-dac: better handle reset controller failuresEtienne Carriere
Use devm_reset_control_get_optional_exclusive() instead of devm_reset_control_get_exclusive() as reset controller is optional. Nevertheless if reset controller is expected but reports an error, propagate the error code to the caller. In such case a nice error trace is emitted unless we're deferring the probe operation.

The ds4424_get_value function takes channel number as it's 3rd argument and translates it internally into I2C address using DS4424_DAC_ADDR macro. The caller ds4424_verify_chip was passing an already translated I2C address as its last argument.

2019-04-22iio: dac: ad5758: Modifications for new revisionMircea Caprioru
This patch will ensure compatibility with the new revision of the AD5758 dac converter. The modifications consist of removing the fault_prot_switch function since this option is no longer available, and enabling the ENABLE_PPC_BUFFERS bit in ADC_CONFIG register before setting the PPC current mode. The previous version of the chip was never released to customers so there is no need to support it going forwards.

2019-04-04iio:dac:ad5064 mlock cleanup - move to a local lock.Jonathan Cameron
indio_dev->mlock is intended to protect state transitions in the core. It's scope is tightly defined. For device specific uses such as those made here, we should define a local lock allowing the scope of the lock to be defined near to what it is protecting. These mlock changes can be non obvious, but given we don't do anything other than direct for DACs, these ones are easy to do. If anyone wants to help with this particular effort it would be most welcome! Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
