The palmas gpadc block has support for monitoring up to 2 ADC channels and issue an interrupt if they reach past a set threshold. This change hooks into the IIO events system and exposes to userspace the ability to configure these threshold values for each channel, but only allow up to 2 such thresholds to be enabled at any given time. Trying to enable a third channel will result in an error. Userspace is expected to input calibrated, as opposed to raw, values as threshold. However, it is not enough to do the opposite of what is done when converting the other way around. To account for tolerances in the ADC, the calculated raw threshold should be adjusted based on the ADC specifications for the device. These specifications include the integral nonlinearity (INL), offset, and gain error. To adjust the high threshold, use the following equation: (calibrated value + INL) * Gain error + offset = maximum value [1] Likewise, use the following equation for the low threshold: (calibrated value - INL) * Gain error - offset = minimum value The gain error is a combination of gain error, as listed in the datasheet, and gain error drift due to temperature and supply. The exact values for these specifications vary between palmas devices. This patch sets the values found in TWL6035, TWL6037 datasheet.

The palmas gpadc block has support for monitoring up to 2 ADC channels and issue an interrupt if they reach past a set threshold. This is currently used to wake up the system from sleep, but the functionality is more generic than that. As such, change the naming of functions and variables to refer to it as events instead, except during suspend and resume where wakeup still make sense.

It does not seem to be used by anyone and later patches in this series are made simpler by first removing this. There is now a lot of dead code that cannot be reached, until later patches revive it. Arguably, this is preferred over removing the code only to add it again.

ROHM BU27034 is an ambient light sensor with 3 channels and 3 photo diodes capable of detecting a very wide range of illuminance. Typical application is adjusting LCD and backlight power of TVs and mobile phones. Add initial support for the ROHM BU27034 ambient light sensor. NOTE: - Driver exposes 4 channels. One IIO_LIGHT channel providing the calculated lux values based on measured data from diodes #0 and #1. In addition, 3 IIO_INTENSITY channels are emitting the raw register data from all diodes for more intense user-space computations. - Sensor has GAIN values that can be adjusted from 1x to 4096x. - Sensor has adjustible measurement times of 5, 55, 100, 200 and 400 mS. Driver does not support 5 mS which has special limitations. - Driver exposes standard 'scale' adjustment which is implemented by: 1) Trying to adjust only the GAIN 2) If GAIN adjustment alone can't provide requested scale, adjusting both the time and the gain is attempted. - Driver exposes writable INT_TIME property that can be used for adjusting the measurement time. Time adjustment will also cause the driver to try to adjust the GAIN so that the overall scale is kept as close to the original as possible.

Some light sensors can adjust both the HW-gain and integration time. There are cases where adjusting the integration time has similar impact to the scale of the reported values as gain setting has. IIO users do typically expect to handle scale by a single writable 'scale' entry. Driver should then adjust the gain/time accordingly. It however is difficult for a driver to know whether it should change gain or integration time to meet the requested scale. Usually it is preferred to have longer integration time which usually improves accuracy, but there may be use-cases where long measurement times can be an issue. Thus it can be preferable to allow also changing the integration time - but mitigate the scale impact by also changing the gain underneath. Eg, if integration time change doubles the measured values, the driver can reduce the HW-gain to half. The theory of the computations of gain-time-scale is simple. However, some people (undersigned) got that implemented wrong for more than once. Add some gain-time-scale helpers in order to not dublicate errors in all drivers needing these computations.

A few IIC channel descriptions explained used units as: data is in foo "that can be processed into an" [unit] value. The "can be processed into" is quite broad statement as it does not really explain what this processing means. This makes units pretty much useless. After discussion with Jonathan, it seems the units for these channels should also be well-defined as for all other channels. The processing means the standard scale and offset application that is used throughout the IIO. Let's make it more obvious by stating that the units are [unit] after scale ane offset are applied.

ADC sample captures take a certain amount of time to complete after initiated; this conversion time range can be anywhere from 5 microseconds to 53.68 seconds depending on the configuration of the Analog Input Frame Timer register. When the conversion is in progress, the ADC Status register CNV bit is high. Call regmap_read_poll_timeout() to poll until the ADC conversion is completed (or timeout if more than 53.68 seconds passes).

Pull compute express link (cxl) fixes from Dan Williams: "Several fixes for driver startup regressions that landed during the merge window as well as some older bugs. The regressions were due to a lack of testing with what the CXL specification calls Restricted CXL Host (RCH) topologies compared to the testing with Virtual Host (VH) CXL topologies. A VH topology is typical PCIe while RCH topologies map CXL endpoints as Root Complex Integrated endpoints. The impact is some driver crashes on startup. This merge window also added compatibility for range registers (the mechanism that CXL 1.1 defined for mapping memory) to treat them like HDM decoders (the mechanism that CXL 2.0 defined for mapping Host-managed Device Memory). That work collided with the new region enumeration code that was tested with CXL 2.0 setups, and fails with crashes at startup. Lastly, the DOE (Data Object Exchange) implementation for retrieving an ACPI-like data table from CXL devices is being reworked for v6.4. Several fixes fell out of that work that are suitable for v6.3. All of this has been in linux-next for a while, and all reported issues [1] have been addressed. Summary: - Fix several issues with region enumeration in RCH topologies that can trigger crashes on driver startup or shutdown. - Fix CXL DVSEC range register compatibility versus region enumeration that leads to startup crashes - Fix CDAT endiannes handling - Fix multiple buffer handling boundary conditions - Fix Data Object Exchange (DOE) workqueue usage vs CONFIG_DEBUG_OBJECTS warn splats" Link: http://lore.kernel.org/r/20230405075704.33de8121@canb.auug.org.au [1] * tag 'cxl-fixes-6.3-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: cxl/hdm: Extend DVSEC range register emulation for region enumeration cxl/hdm: Limit emulation to the number of range registers cxl/region: Move coherence tracking into cxl_region_attach() cxl/region: Fix region setup/teardown for RCDs cxl/port: Fix find_cxl_root() for RCDs and simplify it cxl/hdm: Skip emulation when driver manages mem_enable cxl/hdm: Fix double allocation of @cxlhdm PCI/DOE: Fix memory leak with CONFIG_DEBUG_OBJECTS=y PCI/DOE: Silence WARN splat with CONFIG_DEBUG_OBJECTS=y cxl/pci: Handle excessive CDAT length cxl/pci: Handle truncated CDAT entries cxl/pci: Handle truncated CDAT header cxl/pci: Fix CDAT retrieval on big endian
