2022-07-20gpio: i8255: Introduce the Intel 8255 interface library moduleWilliam Breathitt Gray
Exposes consumer library functions providing support for interfaces compatible with the venerable Intel 8255 Programmable Peripheral Interface (PPI). The Intel 8255 PPI first appeared in the early 1970s, initially for the Intel 8080 and later appearing in the original IBM-PC. The popularity of the original Intel 8255 chip led to many subsequent variants and clones of the interface in various chips and integrated circuits. Although still popular, interfaces compatible with the Intel 8255 PPI are nowdays typically found embedded in larger VLSI processing chips and FPGA components rather than as discrete ICs. A CONFIG_GPIO_I8255 Kconfig option is introduced by this patch. Modules wanting access to these i8255 library functions should select this Kconfig option, and import the I8255 symbol namespace.

2022-07-20watchdog/pseries-wdt: initial support for H_WATCHDOG-based watchdog timersScott Cheloha
PAPR v2.12 defines a new hypercall, H_WATCHDOG. The hypercall permits guest control of one or more virtual watchdog timers. The timers have millisecond granularity. The guest is terminated when a timer expires. This patch adds a watchdog driver for these timers, "pseries-wdt". pseries_wdt_probe() currently assumes the existence of only one platform device and always assigns it watchdogNumber 1. If we ever expose more than one timer to userspace we will need to devise a way to assign a distinct watchdogNumber to each platform device at device registration time.

2022-07-20irqchip: Add LoongArch CPU interrupt controller supportHuacai Chen
LoongArch CPUINTC stands for CSR.ECFG/CSR.ESTAT and related interrupt controller that described in Section 7.4 of "LoongArch Reference Manual, Vol 1". For more information please refer Documentation/loongarch/irq- chip-model.rst. LoongArch CPUINTC has 13 interrupt sources: SWI0~1, HWI0~7, IPI, TI (Timer) and PCOV (PMC). IRQ mappings of HWI0~7 are configurable (can be created from DT/ACPI), but IPI, TI (Timer) and PCOV (PMC) are hardcoded bits, so we expose the fwnode_handle to map them, and get mapped irq by irq_create_mapping when using them.

EIOINTC stands for "Extended I/O Interrupts" that described in Section 11.2 of "Loongson 3A5000 Processor Reference Manual". For more information please refer Documentation/loongarch/irq-chip-model.rst. Loongson-3A5000 has 4 cores per NUMA node, and each NUMA node has an EIOINTC; while Loongson-3C5000 has 16 cores per NUMA node, and each NUMA node has 4 EIOINTCs. In other words, 16 cores of one NUMA node in Loongson-3C5000 are organized in 4 groups, each group connects to an EIOINTC. We call the "group" here as an EIOINTC node, so each EIOINTC node always includes 4 cores (both in Loongson-3A5000 and Loongson- 3C5000).

2022-07-20ACPI: irq: Allow acpi_gsi_to_irq() to have an arch-specific fallbackMarc Zyngier
It appears that the generic version of acpi_gsi_to_irq() doesn't fallback to establishing a mapping if there is no pre-existing one while the x86 version does. While arm64 seems unaffected by it, LoongArch is relying on the x86 behaviour. In an effort to prevent new architectures from reinventing the proverbial wheel, provide an optional callback that the arch code can set to restore the x86 behaviour. Hopefully we can eventually get rid of this in the future once the expected behaviour has been clarified.

2022-07-20APCI: irq: Add support for multiple GSI domainsMarc Zyngier
In an unfortunate departure from the ACPI spec, the LoongArch architecture split its GSI space across multiple interrupt controllers. In order to be able to reuse the core code and prevent architectures from reinventing an already square wheel, offer the arch code the ability to register a dispatcher function that will return the domain fwnode for a given GSI. The ARM GIC drivers are updated to support this (with a single domain, as intended).

2022-07-20net: ipa: initialize ring indexes to 0Alex Elder
When a GSI channel is initially allocated, and after it has been reset, the hardware assumes its ring index is 0. And although we do initialize channels this way, the comments in the IPA code don't really explain this. For event rings, it doesn't matter what value we use initially, so using 0 is just fine. Add some information about the assumptions made by hardware above the definition of the gsi_ring structure in "gsi.h". Zero the index field for all rings (channel and event) when the ring is allocated. As a result, that function initializes all fields in the structure. Stop zeroing the index the top of gsi_channel_program(). Initially we'll use the index value set when the channel ring was allocated. And we'll explicitly zero the index value in gsi_channel_reset() before programming the hardware, adding a comment explaining why it's required. For event rings, use the index initialized by gsi_ring_alloc() rather than 0 when ringing the doorbell in gsi_evt_ring_program(). (It'll still be zero, but we won't assume that to be the case.) Use a local variable in gsi_evt_ring_program() that represents the address of the event ring's ring structure. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.

2022-07-20mlxsw: spectrum_router: Fix IPv4 nexthop gateway indicationIdo Schimmel
mlxsw needs to distinguish nexthops with a gateway from connected nexthops in order to write the former to the adjacency table of the device. The check used to rely on the fact that nexthops with a gateway have a 'link' scope whereas connected nexthops have a 'host' scope. This is no longer correct after commit 747c14307214 ("ip: fix dflt addr selection for connected nexthop"). Fix that by instead checking the address family of the gateway IP.

2022-07-19drm/i915/guc: support v69 in parallel to v70Daniele Ceraolo Spurio
This patch re-introduces support for GuC v69 in parallel to v70. As this is a quick fix, v69 has been re-introduced as the single "fallback" guc version in case v70 is not available on disk and only for platforms that are out of force_probe and require the GuC by default. All v69 specific code has been labeled as such for easy identification, and the same was done for all v70 functions for which there is a separate v69 version, to avoid accidentally calling the wrong version via the unlabeled name. When the fallback mode kicks in, a drm_notice message is printed in dmesg to inform the user of the required update. The existing logging of the fetch function has also been updated so that we no longer complain immediately if we can't find a fw and we only throw an error if the fetch of both the base and fallback blobs fails. The plan is to follow this up with a more complex rework to allow for multiple different GuC versions to be supported at the same time. v2: reduce the fallback to platform that require it, switch to firmware_request_nowarn(), improve logs.

2022-07-19drm/i915/guc: Support programming the EU priority in the GuC descriptorMatthew Brost
In GuC submission mode the EU priority must be updated by the GuC rather than the driver as the GuC owns the programming of the context descriptor. Given that the GuC code uses the GuC priorities, we can't use a generic function using i915 priorities for both execlists and GuC submission. The existing function has therefore been pushed to the execlists back-end while a new one has been added for GuC. v2: correctly use the GuC prio.
