2023-06-15spi: stm32: renaming of spi_master into spi_controllerAlain Volmat
Preparing introduction of SPI device, rename the spi_master structure into spi_controller. This doesn't have any functional impact since spi_master was already a macro for spi_controller. Referring now to ctrl instead of master since the spi_controller structure might not be used as a master controller only.

2023-06-06spi: dw: Add compatible for Intel Mount Evans SoCAbe Kohandel
The Intel Mount Evans SoC's Integrated Management Complex uses the SPI controller for access to a NOR SPI FLASH. However, the SoC doesn't provide a mechanism to override the native chip select signal. This driver doesn't use DMA for memory operations when a chip select override is not provided due to the native chip select timing behavior. As a result no DMA configuration is done for the controller and this configuration is not tested. The controller also has an errata where a full TX FIFO can result in data corruption. The suggested workaround is to never completely fill the FIFO. The TX FIFO has a size of 32 so the fifo_len is set to 31.

2023-06-02spi: spi-imx: fix mixing of native and gpio chipselects for imx51/imx53/imx6 ↵Rasmus Villemoes
variants Commit 87c614175bbf (spi: spi-imx: fix MX51_ECSPI_* macros when cs > 3) ensured that the argument passed to the macros was masked with &3, so that we no longer write outside the intended fields in the various control registers. When all chip selects are gpios, this works just fine. However, when a mix of native and gpio chip selects are in use, that masking is too naive. Say, for example, that SS0 is muxed as native chip select, and there is also a chip at 4 (obviously with a gpio cs). In that case, when accessing the latter chip, both the SS0 pin and the gpio pin will be asserted low. The fix for this is to use the ->unused_native_cs value as channel number for any spi device which uses a gpio as chip select.

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-05-30spi: qup: Request DMA before enabling clocksStephan Gerhold
It is usually better to request all necessary resources (clocks, regulators, ...) before starting to make use of them. That way they do not change state in case one of the resources is not available yet and probe deferral (-EPROBE_DEFER) is necessary. This is particularly important for DMA channels and IOMMUs which are not enforced by fw_devlink yet (unless you use fw_devlink.strict=1). spi-qup does this in the wrong order, the clocks are enabled and disabled again when the DMA channels are not available yet. This causes issues in some cases: On most SoCs one of the SPI QUP clocks is shared with the UART controller. When using earlycon UART is actively used during boot but might not have probed yet, usually for the same reason (waiting for the DMA controller). In this case, the brief enable/disable cycle ends up gating the clock and further UART console output will halt the system completely. Avoid this by requesting the DMA channels before changing the clock state.

2023-05-23spi: spi-imx: use "controller" variable consistently in spi_imx_probe()Rasmus Villemoes
Near the top of the function, spi_imx->controller is set to controller (and is of course never modified again). The rest of the function uses a mix of the two expressions. For consistency, readability and better code generation, drop all the spi_imx-> indirections.

2023-05-22spi: spi-cadence: Interleave write of TX and read of RX FIFOCharles Keepax
When working in slave mode it seems the timing is exceedingly tight. The TX FIFO can never empty, because the master is driving the clock so zeros would be sent for those bytes where the FIFO is empty. Return to interleaving the writing of the TX FIFO and the reading of the RX FIFO to try to ensure the data is available when required.

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux Pull perf tools fixes from Arnaldo Carvalho de Melo: - Fail graciously if BUILD_BPF_SKEL=1 is specified and clang isn't available - Add empty 'struct rq' to 'perf lock contention' to satisfy libbpf 'runqueue' type verification. This feature is built only with BUILD_BPF_SKEL=1 - Make vmlinux.h use bpf.h and perf_event.h in source directory, not system ones that may be old and not have things like 'union perf_sample_weight' - Add system include paths to BPF builds to pick things missing in the headers included by clang -target bpf - Update various header copies with the kernel sources - Change divide by zero and not supported events behavior to show 'nan'/'not counted' in 'perf stat' output. This happens when using things like 'perf stat -M TopdownL2 true', involving JSON metrics - Update no event/metric expectations affected by using JSON metrics in 'perf stat -ddd' perf test - Avoid segv with 'perf stat --topdown' for metrics without a group - Do not assume which events may have a PMU name, allowing the logic to keep an AUX event group together.
