* fpga: region: fix kernel-docYang Li2021-12-101-1/+1
| | | | | | | | | | | | | | Fix function name in of-fpga-region.c kernel-doc comment to remove a warning found by running scripts/kernel-doc, which is caused by using 'make W=1'. drivers/fpga/of-fpga-region.c:451: warning: expecting prototype for fpga_region_init().

* fpga: region: Use standard dev_release for class driverRuss Weight2021-11-284-99/+59
| | | | | | | | | | | | | | | | | | The FPGA region class driver data structure is being treated as a managed resource instead of using the standard dev_release call-back function to release the class data structure. This change removes the managed resource code and combines the create() and register() functions into a single register() or register_full() function. The register_full() function accepts an info data structure to provide flexibility in passing optional parameters. The register() function supports the current parameter list for users that don't require the use of optional parameters.

* fpga: ice40-spi: Add SPI device ID tableMark Brown2021-09-271-0/+7
| | | | | | | | | | | Currently autoloading for SPI devices does not use the DT ID table, it uses SPI modalises. Supporting OF modalises is going to be difficult if not impractical, an attempt was made but has been reverted, so ensure that module autoloading works for this driver by adding a SPI ID table.

This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The performance reporting driver added cpu hotplug feature but it didn't add pmu migration call in cpu offline function. This can create an issue incase the current designated cpu being used to collect fme pmu data got offline, as based on current code we are not migrating fme pmu to new target cpu. Because of that perf will still try to fetch data from that offline cpu and hence we will not get counter data. Patch fixed this issue by adding pmu_migrate_context call in fme_perf_offline_cpu function.

Silicom Lightning Creek cards). The N5010 features an FPGA that manages/interfaces four QSFP ports, and allows on-board custom packet processing/filtering/routing, based on logic loaded with user-provided FPGA bitstreams. The N5011 cards adds a PCIe switch that exposes, in addition to the FPGA itself, two Intel E810 (aka Columbiaville) ethernet controllers. With this, packets can be forwarded from the FPGA to the host for further processing.

| * arm64: socfpga: merge Agilex and N5X into ARCH_INTEL_SOCFPGAKrzysztof Kozlowski2021-03-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Agilex, N5X and Stratix 10 share all quite similar arm64 hard cores and SoC-part. Up to a point that N5X uses the same DTSI as Agilex. From the Linux kernel point of view these are flavors of the same architecture so there is no need for three top-level arm64 architectures. Simplify this by merging all three architectures into ARCH_INTEL_SOCFPGA and dropping the other ARCH* arm64 Kconfig entries. The side effect is that the INTEL_STRATIX10_SERVICE will now be available for both 32-bit and 64-bit Intel SoCFPGA, even though it is used only for 64-bit.
