Merge tag 'acpi-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI updates from Rafael Wysocki: "These rearrange the ACPI documentation by converting it to the .rst format and splitting it into clear categories (admin guide, driver API, firmware guide), switch over multiple users of a problematic library function to a new better one, update the ACPICA code in the kernel to a new upstream release, fix a few issues, improve power device management diagnostics and do some cleanups. Specifics: - Convert the ACPI documentation in the kernel source tree to the .rst format and split it into the admin guide, driver API and firmware guide parts (Changbin Du). - Add a PRP0001 usage example to the ACPI documentation (Thomas Preston). - Switch over the users of the acpi_dev_get_first_match_name() library function which turned out to be problematic to a new, better one called acpi_dev_get_first_match_dev() (Andy Shevchenko, YueHaibing). - Update the ACPICA code in the kernel to upstream release 20190405 including: * Null pointer dereference check in acpi_ns_delete_node() (Erik Schmauss). * Multiple macro and function name changes (Bob Moore). * Predefined operation region name fix (Erik Schmauss). - Fix hibernation issue on systems using the Baytrail and Cherrytrail Intel SoCs introduced during the 4.20 development cycle (Hans de Goede). - Add Sony VPCEH3U1E to the backlight quirk list (Zhang Rui). - Fix button handling during system resume (Zhang Rui). - Add a device PM diagnostic message (Rafael Wysocki). - Clean up the code, comments and white space in multiple places (Bjorn Helgaas, Gustavo Silva, Kefeng Wang)" * tag 'acpi-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (53 commits) Documentation: ACPI: move video_extension.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move ssdt-overlays.txt to admin-guide/acpi and convert to reST Documentation: ACPI: move lpit.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move cppc_sysfs.txt to admin-guide/acpi and convert to reST Documentation: ACPI: move apei/einj.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move apei/output_format.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move aml-debugger.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move method-tracing.txt to firmware-guide/acpi and convert to rsST Documentation: ACPI: move debug.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move dsd/data-node-references.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move dsd/graph.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move acpi-lid.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move i2c-muxes.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move dsdt-override.txt to admin-guide/acpi and convert to reST Documentation: ACPI: move initrd_table_override.txt to admin-guide/acpi and convert to reST Documentation: ACPI: move method-customizing.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move gpio-properties.txt to firmware-guide/acpi and convert to reST Documentation: ACPI: move DSD-properties-rules.txt to firmware-guide/acpi and covert to reST Documentation: ACPI: move scan_handlers.txt to driver-api/acpi and convert to reST Documentation: ACPI: move linuxized-acpica.txt to driver-api/acpi and convert to reST ...
