2021-12-23Documentation: livepatch: Add livepatch API pageDavid Vernet4-4/+35
The livepatch subsystem has several exported functions and objects with kerneldoc comments. Though the livepatch documentation contains handwritten descriptions of all of these exported functions, they are currently not pulled into the docs build using the kernel-doc directive. In order to allow readers of the documentation to see the full kerneldoc comments in the generated documentation files, this change adds a new Documentation/livepatch/api.rst page which contains kernel-doc directives to link the kerneldoc comments directly in the documentation. With this, all of the hand-written descriptions of the APIs now cross-reference the kerneldoc comments on the new Livepatching APIs page, and running ./scripts/find-unused-docs.sh on kernel/livepatch no longer shows any files as missing documentation. Note that all of the handwritten API descriptions were left alone with the exception of Documentation/livepatch/system-state.rst, which was updated to allow the cross-referencing to work correctly. The file now follows the cross-referencing formatting guidance specified in Documentation/doc-guide/kernel-doc.rst. Furthermore, some comments around klp_shadow_free_all() were updated to say <_, id> rather than <*, id> to match the rest of the file, and to prevent the docs build from emitting an "Inline emphasis start-string without end string" error.

Tree rebased today to fix up some trivial issues + pull in a fix that was previously on the fixes-togreg branch. Vast majority have been in linux-next for some time now. New device support * adi,ad7293 - New driver and bindings for this Power Amplifier drain current controller. A complex device with various related monitoring functions. * adi,ad75513R - New driver and bindings for this combined ADC and DAC device. - A few follow up fixes. * adi,admv8818 - New driver (and type) for this 2-18GHz filter device. Includes bindings and ABI documentation to allow clk_notifier based auto adjustment of the filters in appropriate applications. * liteon,ltr501 - Support for the ltr303. ID and chip specific info table. * xilinx,ams - New generic firmware function fwnode_iomap() as used in this driver. - New driver and bindings for this ADC and on-chip sensors as found in various Xilinx devices. Core * Introduced IIO_VAL_INT_64 which uses val and val2 in IIO callbacks to form a 64 bit integer when higher precision needed. * Allow IIO_ENUM_AVAILABLE to be used with different shared values. * Fix a long term issue with scheduling whilst atomic when iio_trig_poll() is called but no trigger consumers are actually enabled and hence the trigger may be reenabled from the interrupt handler. Seen in the wild on the tsc2046. * Mark iio_device_type const. * buffer: Use a separate index variable to simplify code. * buffer-dma: Clear out unused struct iio_buffer_block * buffer-dmaengine: Switch to cheaper round_down() as power of 2 values. Tests/tools * format_value - Check against NULL returns from allocations in tests. - Add IIO_VAL_INT_64 test case. * event_monitor - Flush the output after event to given more consistent latency when tool output piped to other programs. Driver Features * axp20x - Add support for NTC thermistor channel and document TS pin binding. * arm,scmi - Add reading of raw channel values (using IIO_VAL_INT_64) * liteon,ltr501 - Add proximity-near-level support and dt-binding. Tree wide cleanup * Remove no-op trigger ops from multiple drivers. * Stop using dev_get_drvdata() on the iio_dev->dev in various drivers and then stop assigning it to allow this to be used for other purposes. We can always get to the indio_dev using dev_to_iio_dev() which is a container_of() based approach.

2021-12-22asm-generic: introduce io_stop_wc() and add implementation for ARM64Xiongfeng Wang1-0/+8
For memory accesses with write-combining attributes (e.g. those returned by ioremap_wc()), the CPU may wait for prior accesses to be merged with subsequent ones. But in some situation, such wait is bad for the performance. We introduce io_stop_wc() to prevent the merging of write-combining memory accesses before this macro with those after it. We add implementation for ARM64 using DGH instruction and provide NOP implementation for other architectures.

The PL330 was commented out because its binding wasn't converted to a schema. With the binding converted, the example now needs several updates. However, while it's possible that the PL330 has a 'cci-control-port', there aren't any platforms upstream which do. So rather than allowing 'cci-control-port' in the PL330 binding, let's just drop the example. Cc: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com> Signed-off-by: Rob Herring <robh@kernel.org>
