2022-08-16iio: adc: at91-sama5d2_adc: add 64 and 256 oversampling ratioClaudiu Beznea1-5/+26
Add 64 and 256 oversampling ratio support. It is necessary for temperature sensor. Signed-off-by: Claudiu Beznea <claudiu.beznea@microchip.com> Link: https://lore.kernel.org/r/20220803102855.2191070-12-claudiu.beznea@microchip.com Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2022-08-16iio: adc: at91-sama5d2_adc: adjust osr based on specific platform dataClaudiu Beznea1-13/+22
ADC captures data on 12 bits (if oversampling is not enabled). When using oversampling captured data could go up to 14 bits for SAMA5D2 or up to 16 bits for SAMA7G5 (depending on oversampling settings). All the channels that are subject of oversampling are registered as 14 or 16 real bits. Depending on the oversampling settings the ADC converted value need to be shifted up to 14 or 16 to cope with realbits value registered to IIO subsystem. Commit adds platform specific information to know if we run on a system with up to 14 or 16 bits ADC converted data.

2022-08-16iio: adc: at91-sama5d2_adc: exit from write_raw() when buffers are enabledClaudiu Beznea1-0/+10
When buffers are enabled conversion may start asynchronously thus allowing changes on actual hardware could lead to bad behavior. Thus do not allow changing oversampling ratio and sample frequency when if iio_device_claim_direct_mode() returns with error.

2022-08-16iio: adc: at91-sama5d2_adc: disable/prepare buffer on suspend/resumeClaudiu Beznea1-7/+7
In case triggered buffers are enabled while system is suspended they will not work anymore after resume. For this call at91_adc_buffer_postdisable() on suspend and at91_adc_buffer_prepare() on resume. On tests it has been seen that at91_adc_buffer_postdisable() call is not necessary but it has been kept because it also does the book keeping for DMA. On resume path there is no need to call at91_adc_configure_touch() as it is embedded in at91_adc_buffer_prepare().

2022-08-16iio: adc: at91-sama5d2_adc: lock around oversampling and sample freqClaudiu Beznea1-4/+8
.read_raw()/.write_raw() could be called asynchronously from user space or other in kernel drivers. Without locking on st->lock these could be called asynchronously while there is a conversion in progress. Read will be harmless but changing registers while conversion is in progress may lead to inconsistent results. Thus, to avoid this lock st->lock.

2022-08-14afs: Enable multipage folio supportDavid Howells2-1/+3
Enable multipage folio support for the afs filesystem. Support has already been implemented in netfslib, fscache and cachefiles and in most of afs, but I've waited for Matthew Wilcox's latest folio changes. Note that it does require a change to afs_write_begin() to return the correct subpage. This is a "temporary" change as we're working on getting rid of the need for ->write_begin() and ->write_end() completely, at least as far as network filesystems are concerned - but it doesn't prevent afs from making use of the capability.

2022-08-13perf test: Refactor shell tests allowing subdirsCarsten Haitzler4-134/+238
This is a prelude to adding more tests to shell tests and in order to support putting those tests into subdirectories, I need to change the test code that scans/finds and runs them. To support subdirs I have to recurse so it's time to refactor the code to allow this and centralize the shell script finding into one location and only one single scan that builds a list of all the found tests in memory instead of it being duplicated in 3 places. This code also optimizes things like knowing the max width of desciption strings (as we can do that while we scan instead of a whole new pass of opening files). It also more cleanly filters scripts to see only *.sh files thus skipping random other files in directories like *~ backup files, other random junk/data files that may appear and the scripts must be executable to make the cut (this ensures the script lib dir is not seen as scripts to run). This avoids perf test running previous older versions of test scripts that are editor backup files as well as skipping perf.data files that may appear and so on.
