counter: Simplify the count_read and count_write callbacks

2019-10-18T18:47:27Z

The count_read and count_write callbacks are simplified to pass val as unsigned long rather than as an opaque data structure. The opaque counter_count_read_value and counter_count_write_value structures, counter_count_value_type enum, and relevant counter_count_read_value_set and counter_count_write_value_get functions, are removed as they are no longer used.

Merge branch 'ib-ti-eqep-5.4-rc1' into togreg

2019-10-17T21:08:43Z

Immutable branch being merged in. Created as this also involves moving some dependencies around, outside of the counter subsystem. It's possible it will want to be pulled into other trees.

counter: new TI eQEP driver

2019-10-17T20:53:49Z

This adds a new counter driver for the Texas Instruments Enhanced Quadrature Encoder Pulse (eQEP) module. Only very basic functionality is currently implemented - only enough to be able to read the position. The actual device has many more features which can be added to the driver on an as-needed basis. It is not possible to read the QEPA/B signal values in hardware, so that feature is omitted. The TI_PWMSS kernel option is selected in Kconfig to enable the parent bus, which is needed for power management. Signed-off-by: David Lechner Signed-off-by: Jonathan Cameron

counter/ftm-quaddec: Use device-managed registration API

Make use of devm_counter_register. Then we can remove redundant unregistration API usage to make code simpler. Signed-off-by: Chuhong Yuan Signed-off-by: Jonathan Cameron

Jonathan writes: Second set of IIO device support, features, cleanups and minor fixes for 5.3. A few bits for the counters subsystem mixed in here as well. There are some late breaking fixes as well, which aren't so urgent they can't wait for the merge window. New Device Support * adf4371 - New driver + bindings. - Support the adf4372 PLL. Mostly ID and bindings. * ad8366 (note includes rework of driver needed to allow support for these). - Support the ADL5240 variable gain amplifier (VGA). - Support the ADA4961 digital gain amplifier (DGA). * dps310 - New driver, in several parts from different authors for this temp and pressure sensor. - Includes errata workaround for a temperature reading issue. * stk3310 - Support the stk3335, mostly ID. Features and cleanups * core - drop error handling on debugfs registration. - harden by making sure we don't overrun iio_chan_info_postfix. * docs - convert remaining docs to rst. At somepoint we'll fit these few into the main IIO docs. - improve sampling_frequency_available docs but explaining the range form. * ad_sigma_delta - Drop a pointless goto. * ad2s1210 - Drop pointless platform data null check seeing as we don't actually use platform data anymore. * ad7124 - Relax limitation on channel numbers to allow pseudo different channels. - Support control of whether the input is buffered via DT. - Use dynamic allocation for channel configuration to make it easier to support new devices. - YAML binding conversion. * ad7150 - Comment tidy up. - Consistent and simple if (ret) handling of i2c errors. - FIELD_GET and GENMASK. - Ternary rather than !!(condition) for readability. - Use macros to avoid repetition of channel definitions. * ad7606 - Add software channel config (rather that pin controlled) - Refactor to simplify addition of new part in future. * ad7746 - of_deivce_id table. * ad7780 - MAINTAINERS entry - YAML DT bindings. * ad8366 - Stop using core mlock in favour of well scoped local lock. - SPDX + copyright date update. * ad9834 - of_device_id table * adf4371 - Add support for output stage muting before lock on has occured. * adis library - MAINTAINERS entry to reflect that this now Alexandru's problem ;) * adis162xx: - Fix a slightly incorrect set of comments and print statements on minimum supported voltage. * adis16203 - of_device_id table. * adis16240 - Add of_device_id table (in two parts as first patch only used it for MODULE_DEVICE_TABLE.) * adt7316-spi - of_device_id table * adxl372 - YAML DT binding conversion. - Cleanup use of buffer callback functions (precursor to core rework). * bh1710 - Simplify getting the i2c adapter from the client. * dht11 - Mote to newer GPIO consumer interface. * kxcjk-1013.c - Add binding for sensor in display of some ultrabooks after userspace tools updated for it not be a problem to report two similar sensors. * imx7d - drop unused variables. - white space - define instead of variable for clock frequency that is fixed. - drop pointless error message. * messon_saradc - SPDX * sps30 - MAINTAINERS entry - YAML binding conversion. * st_accel - Tidy up ordering in various buffer related callbacks. This is part of a long running effort to simplify the core code. * stm32-dfsdm: - Manage the resolution cleanly in triggerd modes. - Add fast mode support which allows more flexible filter choices. - Add a comment on the reason for a 16 bit record when technically not 'required'. * st_lsm6dsx - Embed device name in the sensor_settings struct as i3c doesn't have a convenient name field to use for this. * xilinx-adc - Relax constraints on supported platforms to reflect that this can used with FPGAs on PCIe cards and hence many architectures. * counters/ftm-quaddec - Fix some formatting io MODULE_AUTHOR - MAINTAINERS entry Fixes * tools - fix incorrect handling of 32 bit channels. * sca3000 - Potential endian bug that is unlikely to bite anyone (be64 host seems unlikely for this old part). * stm32-adc - Add vdda-supply. On some boards it needs to be turned on to supply the ADC. DT bindings included. * stm32-dfsdm - Fix output resolution to work with filter orders other than 3. - Fix output datatype as it's signed and previously claimed not to be. * tag 'iio-for-5.3b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (68 commits) iio: iio-utils: Fix possible incorrect mask calculation iio: frequency: adf4371: Add support for output stage mute dt-bindings: iio: frequency: Add ADF4372 PLL documentation iio: frequency: adf4371: Add support for ADF4372 PLL dt-bindings: iio: adc: Add buffered input property Convert AD7124 bindings documentation to YAML format. iio: adc: ad7124: Shift to dynamic allocation for channel configuration iio: adc: ad7124: Add buffered input support iio: adc: ad7124: Remove input number limitation MAINTAINERS: add ADIS IMU driver library entry iio: adis162xx: fix low-power docs & reports counter/ftm-quaddec: Add missing '>' in MODULE_AUTHOR iio: core: no need to check return value of debugfs_create functions docs: iio: convert to ReST iio: adc: stm32-adc: add missing vdda-supply dt-bindings: iio: adc: stm32: add missing vdda supply iio: adc: stm32-dfsdm: add comment for 16 bits record iio: adc: stm32-dfsdm: add fast mode support iio: adc: stm32-dfsdm: manage data resolution in trigger mode iio: adc: stm32-dfsdm: fix data type ...
