Pull device properties framework updates from Rafael Wysocki: "These introduce fwnode operations for all of the separate types of 'firmware nodes' that can be handled by the device properties framework, make the framework use const fwnode arguments all over, add a helper for the consolidated handling of node references and switch over the framework to the new UUID API. Specifics: - Introduce fwnode operations for all of the separate types of 'firmware nodes' that can be handled by the device properties framework and drop the type field from struct fwnode_handle (Sakari Ailus, Arnd Bergmann). - Make the device properties framework use const fwnode arguments where possible (Sakari Ailus). - Add a helper for the consolidated handling of node references to the device properties framework (Sakari Ailus). - Switch over the ACPI part of the device properties framework to the new UUID API (Andy Shevchenko)" * tag 'devprop-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: device property: Switch to use new generic UUID API device property: export irqchip_fwnode_ops device property: Introduce fwnode_property_get_reference_args device property: Constify fwnode property API device property: Constify argument to pset fwnode backend ACPI: Constify internal fwnode arguments ACPI: Constify acpi_bus helper functions, switch to macros ACPI: Prepare for constifying acpi_get_next_subnode() fwnode argument device property: Get rid of struct fwnode_handle type field ACPI: Use IS_ERR_OR_NULL() instead of non-NULL check in is_acpi_data_node()

ACPI / blacklist: add acpi_match_platform_list()

2017-08-28T23:42:48Z

ACPI OEM ID / OEM Table ID / Revision can be used to identify a platform based on ACPI firmware info. acpi_blacklisted(), intel_pstate_platform_pwr_mgmt_exists(), and some other funcs, have been using similar check to detect a list of platforms that require special handlings. Move the platform check in acpi_blacklisted() to a new common utility function, acpi_match_platform_list(), so that other drivers do not have to implement their own version. There is no change in functionality. Signed-off-by: Toshi Kani Reviewed-by: Borislav Petkov Signed-off-by: Rafael J. Wysocki

ACPI: Introduce DMA ranges parsing

2017-08-07T12:28:51Z

Some devices have limited addressing capabilities and cannot reference the whole memory address space while carrying out DMA operations (eg some devices with bus address bits range smaller than system bus - which prevents them from using bus addresses that are otherwise valid for the system). The ACPI _DMA object allows bus devices to define the DMA window that is actually addressable by devices that sit upstream the bus, therefore providing a means to parse and initialize the devices DMA masks and addressable DMA range size. By relying on the generic ACPI kernel layer to retrieve and parse resources, introduce ACPI core code to parse the _DMA object.

tty: pl011: fix initialization order of QDF2400 E44

2017-07-30T14:53:44Z

The work-around for Qualcomm Technologies QDF2400 Erratum 44 hinges on a global variable defined in the pl011 driver. The ACPI SPCR parsing code determines whether the work-around is needed, and if so, it changes the console name from "pl011" to "qdf2400_e44". The expectation is that the pl011 driver will implement the work-around when it sees the console name. The global variable qdf2400_e44_present is set when that happens. The problem is that work-around needs to be enabled when the pl011 driver probes, not when the console name is queried. However, sbsa_probe() is called before pl011_console_match(). The work-around appeared to work previously because the default console on QDF2400 platforms was always ttyAMA1. The first time sbsa_probe() is called (for ttyAMA0), qdf2400_e44_present is still false. Then pl011_console_match() is called, and it sets qdf2400_e44_present to true. All subsequent calls to sbsa_probe() enable the work-around. The solution is to move the global variable into spcr.c and let the pl011 driver query it during probe time. This works because all QDF2400 platforms require SPCR, so parse_spcr() will always be called. pl011_console_match still checks for the "qdf2400_e44" console name, but it doesn't do anything else special.
