2017-06-29iwlwifi: dvm: use macros for format stringsJohannes Berg
Some static checkers (e.g. smatch) complain if a non-constant format string is used, even if that's a static const variable. Since there's no impact on code generation, just change those format strings to be macros. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

In the i5000 and i5400 drivers, the NRECMEMB register is defined as a 16-bit value, which results in wrong shifts in the code, as reported by sparse. In the datasheets ([1], section 3.9.22.20 and [2], section 3.9.22.21), this register is a 32-bit register. A u32 value for the register fixes the wrong shifts warnings and matches the datasheet.

2017-06-29PM / Domains: Handle safely genpd_syscore_switch() call on non-genpd deviceKrzysztof Kozlowski
genpd_syscore_switch() had two problems: 1. It silently assumed that device, it is being called for, belongs to generic power domain and used container_of() on its power domain pointer. Such assumption might not be true always. 2. It iterated over list of generic power domains without holding gpd_list_lock mutex thus list could have been modified at the same time. Usage of genpd_lookup_dev() solves both problems as it is safe a call for non-generic power domains and uses mutex when iterating.

2017-06-29ACPI / EC: Fix media keys not working problem on some Asus laptopsChris Chiu
Some Asus laptops (verified on X550VXK/FX502VD/FX502VE) get no interrupts when pressing media keys thus the corresponding functions are not invoked. It's due to the _GPE defines in DSDT for EC returns differnt value compared to the GPE Number in ECDT. Confirmed with Asus that the vale in ECDT is the correct one. This commit uses DMI quirks to prevent calling _GPE when doing ec_parse_device() and keep the ECDT GPE number setting for the EC device. With previous commit, it is ensured that if there is an ECDT, it can always be kept as boot_ec, this patch thus can implement a quirk on top of the determined ECDT boot_ec.

2017-06-29ACPI / EC: Add support to skip boot stage DSDT probeLv Zheng
We prepared _INI/_STA methods for \_SB, \_SB.PCI0, \_SB.LID0 and \_SB.EC, _HID(PNP0C09)/_CRS/_GPE for \_SB.EC to poke Windows behavior with qemu, we got the following execution sequence: \_SB._INI \_SB.PCI0._STA \_SB.LID0._STA \_SB.EC._STA \_SB.PCI0._INI \_SB.LID0._INI \_SB.EC._INI There is no extra DSDT EC device enumeration process occurring before the main ACPI device enumeration process. That means acpi_ec_dsdt_probe() is not Windows-compatible. Tracking back, it was added by the following commit: Commit: c5279dee26c0e8d7c4200993bfc4b540d2469598 Subject: ACPI: EC: Add some basic check for ECDT data but that commit was misguided. Why we shouldn't enumerate DSDT EC before the main ACPI device enumeration? The only way to know if the DSDT EC is valid would be to evaluate its _STA control method, but it's not safe to evaluate this control method that early and out of the ACPI enumeration process, because _STA may refer to entities (such as resources or ACPI device objects) that may not have been initialized before OSPM starts to enumerate them via the main ACPI device enumeration. But after we had reverted back to the expected behavior, a regression was reported. On that platform, there is no ECDT, but the platform control methods access EC operation region earlier than Linux expects causing some ACPI method execution errors. For this reason, we just go back to old behavior to still probe DSDT EC as the boot EC. However, that turns out to lead to yet another functional breakage and in order to work around all of the problems, we skip boot stage DSDT probe when the ECDT exists so that a later quirk can always use correct ECDT GPE setting.

2017-06-28PCI: Add pci_scan_root_bus_bridge() interfaceLorenzo Pieralisi
The current pci_scan_root_bus() interface is made up of two main code paths: - pci_create_root_bus() - pci_scan_child_bus() pci_create_root_bus() is a wrapper function that allows to create a struct pci_host_bridge structure, initialize it with the passed parameters and register it with the kernel. As the struct pci_host_bridge require additional struct members, pci_create_root_bus() parameters list has grown in time, making it unwieldy to add further parameters to it in case the struct pci_host_bridge gains more members fields to augment its functionality. Since PCI core code provides functions to allocate struct pci_host_bridge, instead of forcing the pci_create_root_bus() interface to add new parameters to cater for new struct pci_host_bridge functionality, it is more suitable to add an interface in PCI core code to scan a PCI bus straight from a struct pci_host_bridge created and customized by each specific PCI host controller driver. Add a pci_scan_root_bus_bridge() function to allow PCI host controller drivers to create and initialize struct pci_host_bridge and scan the resulting bus.

2017-06-28PCI: Initialize bridge release function at bridge allocationLorenzo Pieralisi
The introduction of pci_register_host_bridge() kernel interface allows PCI host controller drivers to create the struct pci_host_bridge object, initialize it and register it with the kernel so that its corresponding PCI bus can be scanned and its devices probed. The host bridge device release function pci_release_host_bridge_dev() is a static function common for all struct pci_host_bridge allocated objects, so in its current form cannot be used by PCI host bridge controllers drivers to initialize the allocated struct pci_host_bridge, which leaves struct pci_host_bridge devices release function uninitialized. Since pci_release_host_bridge_dev() is a function common to all PCI host bridge objects, initialize it in pci_alloc_host_bridge() (ie common host bridge allocation interface) so that all struct pci_host_bridge objects have their release function initialized by default at allocation time, removing the need for exporting the common pci_release_host_bridge_dev() function to other compilation units.

2017-06-28drm: adv7511_audio: Add .get_dai_id callback to map port number to dai idJohn Stultz
ALSA SoC needs to know connected DAI ID for probing. Using the new audio-card-graph approach, ports/endpoints are used to describe how the links are connected. Unfortunately, since ports/endpoints are used as well for video linkages, there are some issues mixing the port ids to the two (video and audio) namespaces. To solve this issue, this patch adds new .get_dai_id callback on hdmi_codec_ops. The will assume that HDMI audio out will be connected to reg = <2>. This will then be remapped to the ALSA SoC side will as DAI 0. Allowing the adv7511's hdmi audio support to be used with the audio-card-graph. Credit to Kuninori Morimoto who's patch to dw-hdmi-i2s-audio.c was what this was mostly copy-pasted from.

2017-06-28drm: dw-hdmi-i2s: add .get_dai_id callback for ALSA SoCKuninori Morimoto
ALSA SoC needs to know connected DAI ID for probing. It is not a big problem if device/driver was only for sound, but getting DAI ID will be difficult if device includes both Video/Sound, like HDMI. To solve this issue, this patch adds new .get_dai_id callback on hdmi_codec_ops. dw-hdmi-i2s will assume that HDMI sound will be connected to reg = <2>. Then, ALSA SoC side will recognized it as DAI 0 ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; /* HDMI Video IN */ }; port@1 { reg = <1>; /* HDMI OUT */ }; port@2 { reg = <2>; /* HDMI Sound IN */ }; }; Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Acked-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Mark Brown <broonie@kernel.org>
2017-06-28regulator: core: Fix voltage change propagations to supply regulatorsTirupathi Reddy
Some regulators support get_voltage() and some support get_voltage_sel() operations but currently we only propagate changes if the regulator has a get_voltage() operation. Also do this if we've got get_voltage_sel() [Rewite commit message for clarity -- broonie] Signed-off-by: Tirupathi Reddy <tirupath@codeaurora.org> Signed-off-by: Mark Brown <broonie@kernel.org>
