* iio: adc: qcom-spmi-rradc: introduce round robin adcCaleb Connolly2022-06-181-0/+1
| | | | | | | | | | | The Round Robin ADC is responsible for reading data about the rate of charge from the USB or DC input ports, it can also read the battery ID (resistence), skin temperature and the die temperature of the pmic. It is found on the PMI8998 and PM660 Qualcomm PMICs.

* iio:adc:ad7280a: Move out of stagingJonathan Cameron2022-02-211-0/+1
| | | | | | | | | | | | | | | | This is a rather unusual device (in IIO anyway). However, it has a near to standard userspace ABI. Note the work to move this out of staging was done against a minimal QEMU model, which doesn't model all the features of the device. I have no intention to upstream the QEMU model as it was developed just to enable this driver cleanup. https://github.com/jic23/qemu/tree/ad7280a-hacks Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Marcelo Schmitt <marcelo.schmitt1@gmail.com> Link: https://lore.kernel.org/r/20220206190328.333093-21-jic23@kernel.org
* iio: adc: Add Xilinx AMS driverAnand Ashok Dumbre2021-12-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The AMS includes an ADC as well as on-chip sensors that can be used to sample external voltages and monitor on-die operating conditions, such as temperature and supply voltage levels. The AMS has two SYSMON blocks. PL-SYSMON block is capable of monitoring off chip voltage and temperature. PL-SYSMON block has DRP, JTAG and I2C interface to enable monitoring from an external master. Out of these interfaces currently only DRP is supported. Other block PS-SYSMON is memory mapped to PS. The AMS can use internal channels to monitor voltage and temperature as well as one primary and up to 16 auxiliary channels for measuring external voltages. The voltage and temperature monitoring channels also have event capability which allows to generate an interrupt when their value falls below or raises above a set threshold.

* iio: adc: add ADC driver for the TI TSC2046 controllerOleksij Rempel2021-05-171-0/+1
| | | | | | | | | | | | | | | | | | Basically the TI TSC2046 touchscreen controller is 8 channel ADC optimized for the touchscreen use case. By implementing it as an IIO ADC device, we can make use of resistive-adc-touch and iio-hwmon drivers. Polled readings are currently not implemented to keep this patch small, so iio-hwmon will not work out of the box for now. So far, this driver was tested with a custom version of resistive-adc-touch driver, since it needs to be extended to make use of Z1 and Z2 channels. The X/Y are working without additional changes.

It is optimized for high performanceover wide bandwidths and ease of use. The product operates at a 250 MSPS conversion rate and is designed for wireless receivers, instrumentation, and test equipment that require a high dynamic range. The ADC requires 1.8 V and 3.3 V power supplies and a low voltage differential input clock for full performance operation. No external reference or driver components are required for many applications. Data outputs are LVDS compatible (ANSI-644 compatible) and include the means to reduce the overall current needed for short trace distances. Since the chip can operate at such high sample-rates (much higher than classical interfaces), it requires that a DMA controller be used to interface directly to the chip and push data into memory. Typically, the AXI ADC IP core is used to interface with it.

The IP core is used for interfacing with analog-to-digital (ADC) converters that require either a high-speed serial interface (JESD204B/C) or a source synchronous parallel interface (LVDS/CMOS). Usually, some other interface type (i.e SPI) is used as a control interface for the actual ADC, while the IP core (controlled via this driver), will interface to the data-lines of the ADC and handle the streaming of data into memory via DMA. Because of this, the AXI ADC driver needs the other SPI-ADC driver to register with it. The SPI-ADC needs to be register via the SPI framework, while the AXI ADC registers as a platform driver. The two cannot be ordered in a hierarchy as both drivers have their own registers, and trying to organize this [in a hierarchy becomes] problematic when trying to map memory/registers. There are some modes where the AXI ADC can operate as standalone ADC, but those will be implemented at a later point in time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a new driver for the ST-Ericsson AB8500 GPADC, which replaces the old driver in drivers/mfd/ab8500-gpadc.c and thus gets rid of another necessarily different custom driver from the times before IIO existed. The AB8500 GPADC can convert 10 different channels and these are used for monitoring voltages in the U8500 chipset, some are used for battery charging, some for temperature monitoring. As this is very core functionality that a lot of drivers depend on and was formerly compiled in with the AB8500 core driver, we deafault it to 'y' in Kconfig: it can be compiled out but it is really not advisible: the platform can for example overheat if we do.

This basic patch configures the device in fast mode, with 32 kSPS and leaves the default sinc5 filter. Two data conversion modes are made available. When data is retrieved by using the read_raw attribute, one shot single conversion mode is set. The continuous conversion mode is enabled when the triggered buffer mechanism is used. To assure correct data retrieval, the driver waits for the interrupt triggered by the low to high transition of the DRDY pin.

* License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman2017-11-021-0/+1

By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

| * iio: adc: Add support for TI ADC108S102 and ADC128S102Jan Kiszka2017-05-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an upstream port of an IIO driver for the TI ADC108S102 and ADC128S102. The former can be found on the Intel Galileo Gen2 and the Siemens SIMATIC IOT2000. For those boards, ACPI-based enumeration is included. Due to the lack of regulators under ACPI, we hard-code the voltage provided to the VA pin of the ADC to 5 V, the value used on Galileo and IOT2000. For DT usage, the regulator "vref-supply" provides this information. Note that DT usage has not been tested.

It's a big one, adding about 350k new lines of crap^Wcode, mostly all in a big dump of media drivers from Intel. But there's other new drivers in here as well, yet-another-wifi driver, new IIO drivers, and a new crypto accelerator. We also deleted a bunch of stuff, mostly in patch cleanups, but also the Android ION code has shrunk a lot, and the Android low memory killer driver was finally deleted, much to the celebration of the -mm developers. All of these have been in linux-next with a few build issues that will show up when you merge to your tree" Merge conflicts in the new rtl8723bs driver (due to the wifi changes this merge window) handled as per linux-next, courtesy of Stephen Rothwell. * tag 'staging-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (1182 commits) staging: fsl-mc/dpio: add cpu <--> LE conversion for dpaa2_fd staging: ks7010: remove line continuations in quoted strings staging: vt6656: use tabs instead of spaces staging: android: ion: Fix unnecessary initialization of static variable staging: media: atomisp: fix range checking on clk_num staging: media: atomisp: fix misspelled word in comment staging: media: atomisp: kmap() can't fail staging: atomisp: remove #ifdef for runtime PM functions staging: atomisp: satm include directory is gone atomisp: remove some more unused files atomisp: remove hmm_load/store/clear indirections atomisp: kill off mmgr_free atomisp: clean up the hmm init/cleanup indirections atomisp: handle allocation calls before init in the hmm layer staging: fsl-dpaa2/eth: Add maintainer for Ethernet driver staging: fsl-dpaa2/eth: Add TODO file staging: fsl-dpaa2/eth: Add trace points staging: fsl-dpaa2/eth: Add driver specific stats staging: fsl-dpaa2/eth: Add ethtool support staging: fsl-dpaa2/eth: Add Freescale DPAA2 Ethernet driver ...
