2021-11-05mfd: arizona: Split of_match table into I2C and SPI versionsCharles Keepax
The Arizona driver has both some devices which only have an I2C interface and some which only have a SPI interface. Currently both of these share an of_match table, but this means inapproriate compatibles are available for each interface. Tidy this up by creating a table for each interface listing only the appropriate compatibles.

2021-11-05dt-bindings: mfd: Convert X-Powers AXP binding to a schemaMaxime Ripard
The X-Powers AXP PMICs are supported by Linux thanks to its device tree binding. Now that we have the DT validation in place, let's convert the device tree bindings for that driver over to a YAML schema.

2021-11-05mfd: qcom-pm8xxx: switch away from using chained IRQ handlersDmitry Baryshkov
PM8xxx PMIC family uses GPIO as parent IRQ. Using it together with the irq_set_chained_handler_and_data() results in warnings from the GPIOLIB (see 461c1a7d4733 ("gpiolib: override irq_enable/disable")) as in this path the IRQ resources are not allocated (and thus the corresponding GPIO is not marked as used for the IRQ. Use request_irq so that the IRQ resources are proprely setup.

2021-11-05mfd: max14577: Do not enforce (incorrect) interrupt trigger typeKrzysztof Kozlowski
Interrupt line can be configured on different hardware in different way, even inverted. Therefore driver should not enforce specific trigger type - edge falling - but instead rely on Devicetree to configure it. The Maxim 14577/77836 datasheets describe the interrupt line as active low with a requirement of acknowledge from the CPU therefore the edge falling is not correct. The interrupt line is shared between PMIC and charger driver, so using level sensitive interrupt is here especially important to avoid races. With an edge configuration in case if first PMIC signals interrupt followed shortly after by the RTC, the interrupt might not be yet cleared/acked thus the second one would not be noticed.

The Maxim 77686 datasheet describes the interrupt line as active low with a requirement of acknowledge from the CPU therefore the edge falling is not correct. The interrupt line is shared between PMIC and RTC driver, so using level sensitive interrupt is here especially important to avoid races. With an edge configuration in case if first PMIC signals interrupt followed shortly after by the RTC, the interrupt might not be yet cleared/acked thus the second one would not be noticed.

2021-11-05mfd: sec-irq: Do not enforce (incorrect) interrupt trigger typeKrzysztof Kozlowski
Interrupt line can be configured on different hardware in different way, even inverted. Therefore driver should not enforce specific trigger type - edge falling - but instead rely on Devicetree to configure it. The Samsung PMIC drivers are used only on Devicetree boards. Additionally, the PMIC datasheets describe the interrupt line as active low with a requirement of acknowledge from the CPU therefore the edge falling is not correct. Marek Szyprowski reports that together with DTS change (proper level in DTS) it fixes RTC alarm failure that he observed from time to time on TM2e board.

2021-11-05PCI: Add ACS quirk for Pericom PI7C9X2G switchesNathan Rossi
The Pericom PI7C9X2G404/PI7C9X2G304/PI7C9X2G303 PCIe switches have an erratum for ACS P2P Request Redirect behaviour when used in the cut-through forwarding mode. The recommended work around for this issue is to use the switch in store and forward mode. The erratum results in packets being queued and not being delivered upstream, which can be observed as very poor downstream device performance and/or dropped device-generated data/interrupts. Add a fixup so that when enabling or resuming the downstream port we check if it has enabled ACS P2P Request Redirect, and if so, change the device (via the upstream port) to use the store and forward operating mode.

We need to be a bit careful if going into the scheduler, as a scheduler or queue mappings can arbitrarily change before we have entered the queue. Have the bio scheduler mapping do that separately, it's a very cheap operation compared to actually doing merging locking and lookups.

2021-11-04PCI: apple: Configure RID to SID mapper on device additionMarc Zyngier
The Apple PCIe controller doesn't directly feed the endpoint's Requester ID to the IOMMU (DART), but instead maps RIDs onto Stream IDs (SIDs). The DART and the PCIe controller must thus agree on the SIDs that are used for translation (by using the 'iommu-map' property). For this purpose, parse the 'iommu-map' property each time a device gets added, and use the resulting translation to configure the PCIe RID-to-SID mapper. Similarly, remove the translation if/when the device gets removed. This is all driven from a bus notifier which gets registered at probe time. Hopefully this is the only PCI controller driver in the whole system.
