2024-09-05dt-bindings: spi: nxp-fspi: add imx8ulp supportHaibo Chen1-0/+1
The flexspi on imx8ulp only has 16 number of LUTs, it is different with flexspi on other imx SoC which has 32 number of LUTs.

2024-09-04Add device tree for ArmSoM Sige 5 boardMark Brown1-0/+1
Merge series from Detlev Casanova <detlev.casanova@collabora.com>: Add the rk3576-armsom-sige5 device tree as well as its rk3576.dtsi base and pinctrl information in rk3576-pinctrl.dtsi. The other commits add DT bindings documentation for the devices that already work with the current corresponding drivers. Note that as is, the rockchip gpio driver needs the gpio nodes to be children of the pinctrl node, even though this is deprecated. When the driver supports it, they can be moved out of the pinctrl node. The power-domain@RK3576_PD_USB is a child of power-domain@RK3576_PD_VOP. That looks strange but it is how the hardware is, and confirmed by Rockchip: The NOC bus of USB passes through the PD of VOP, so it relies on VOP PD. The other bindings have been applied on next.

2024-09-04spi: mxs: Switch to RUNTIME/SYSTEM_SLEEP_PM_OPS()Fabio Estevam1-6/+5
Replace SET_RUNTIME_PM_OPS()/SET SYSTEM_SLEEP_PM_OPS() with their modern RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() alternatives. The combined usage of pm_ptr() and RUNTIME_PM_OPS/SYSTEM_SLEEP_PM_OPS() allows the compiler to evaluate if the runtime suspend/resume() functions are used at build time or are simply dead code. This allows removing the __maybe_unused annotations from the suspend/resume() functions.

2024-09-03spi: Revert "spi: Insert the missing pci_dev_put()before return"Nathan Chancellor1-6/+2
Commit 8a0ec8c2d736 ("spi: Insert the missing pci_dev_put()before return") added two uses of pci_dev_put() with an uninitialized dma_dev, resulting in the following compiler warnings (or errors with CONFIG_WERROR) when building with clang: drivers/spi/spi-pxa2xx-pci.c:150:15: error: variable 'dma_dev' is uninitialized when used here [-Werror,-Wuninitialized] 150 | pci_dev_put(dma_dev); | ^~~~~~~ drivers/spi/spi-pxa2xx-pci.c:228:15: error: variable 'dma_dev' is uninitialized when used here [-Werror,-Wuninitialized] 228 | pci_dev_put(dma_dev); | ^~~~~~~ Commit 609d7ffdc421 ("spi: pxa2xx-pci: Balance reference count for PCI DMA device") added a call to pci_dev_put() via devm_add_action_or_reset() in case of failures, so the recent change was incorrect for multiple reasons.

In zynq_qspi_exec_mem_op(), the temporary buffer is allocated with kzalloc and then immediately initialized using memset to 0xff. To optimize this, replace kzalloc with kmalloc, as the zeroing operation is redundant and unnecessary.

Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>: Provide empty versions of acpi_spi_count_resources(), acpi_spi_device_alloc() and acpi_spi_find_controller_by_adev() if the real functions are not being built. This commit fixes two problems with the original definitions: 1) There wasn't an empty version of these functions 2) The #if only depended on CONFIG_ACPI. But the functions are implemented in the core spi.c so CONFIG_SPI_MASTER must also be enabled for the real functions to exist.

2024-07-29Marvell HW overlay support for Cadence xSPIMark Brown2-20/+704
Merge series from Witold Sadowski <wsadowski@marvell.com>: This patch series adds support for the second version of the Marvell hardware overlay for the Cadence xSPI IP block. The overlay is a hardware change made around the original xSPI block. It extends xSPI features with clock configuration, interrupt masking, and full-duplex, variable-length SPI operations. These functionalities allow the xSPI block to operate not only with memory devices but also with simple SPI devices and TPM devices. Example ACPI entry: Device (SPI0) { Name (_HID, "PRP0001") // ACPI_DT_NAMESPACE_HID Name (_UID, 0) Name (_DDN, "SPI controller 0") Name (_CCA, ONE) Method (_STA) {Return (0xF)} Name (_CRS, ResourceTemplate() { QWordMemory ( ResourceConsumer,// ResourceUsage PosDecode, // Decode MinFixed, // MinType MaxFixed, // MaxType NonCacheable, // MemType ReadWrite, // ReadWriteType 0, // AddressGranularity 0x804000000000, // MinAddress 0x804000001037, // MaxAddress 0, // AddressTranslation 0x1038) // AddressLength QWordMemory ( ResourceConsumer,// ResourceUsage PosDecode, // Decode MinFixed, // MinType MaxFixed, // MaxType NonCacheable, // MemType ReadWrite, // ReadWriteType 0, // AddressGranularity 0x804010000000, // MinAddress 0x804010000007, // MaxAddress 0, // AddressTranslation 0x8) // AddressLength QWordMemory ( ResourceConsumer,// ResourceUsage PosDecode, // Decode MinFixed, // MinType MaxFixed, // MaxType NonCacheable, // MemType ReadWrite, // ReadWriteType 0, // AddressGranularity 0x804000002000, // MinAddress 0x804000004027, // MaxAddress 0, // AddressTranslation 0x2028) // AddressLength QWordMemory ( ResourceConsumer,// ResourceUsage PosDecode, // Decode MinFixed, // MinType MaxFixed, // MaxType NonCacheable, // MemType ReadWrite, // ReadWriteType 0, // AddressGranularity 0x804000008000, // MinAddress 0x804000008237, // MaxAddress 0, // AddressTranslation 0x238) // AddressLength Interrupt(ResourceConsumer, Edge, ActiveHigh, Exclusive) { 0x7A } }) Name (_DSD, Package() { ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), Package () { Package () { "compatible", "marvell,cn10-xspi-nor"}, Package () { "reg", 0x8040}, } }) } // SPI0
2024-07-29Add support for AD4000 series of ADCsMark Brown9-6/+344
Merge series from Marcelo Schmitt <marcelo.schmitt@analog.com>: This patch series extends the SPI bitbang, gpio, and spi-engine controllers to support configurable MOSI line idle states. It then introduces the ad4000 driver which uses the MOSI idle configuration to provide improved support for the AD4000 series of ADCs. Documentation is added describing the new extension to the SPI protocol. The currently supported wiring modes for AD4000 devices were documented under IIO documentation directory. Change log v6 -> v7: [Device tree] No changes to device tree from v6 to v7. [SPI] spi.c: Removed blank line added in code not related to MOSI idle feature. spi: bitbang: Rewrapped commit message. spi: bitbang: Rebased bitbang patch on top of spi for-next branch. [IIO] ad4000: Checked gain-milli read from dt and made it match one of supported gains or fail. ad4000: Added blank lines to improve code readability. ad4000: return 0; when known that no errors occurred.

2024-07-29spi: spi-mt65xx: Use threaded interrupt for non-SPIMEM transferAngeloGioacchino Del Regno1-15/+25
In order to avoid blocking for an excessive amount of time, eventually impacting on system responsiveness, interrupt handlers should finish executing in as little time as possible. Use threaded interrupt and move the SPI transfer handling (both CPU and DMA) for the non-spimem case to an interrupt thread instead. For SPI-MEM (IPM) controllers, handling is kept in the blocking interrupt as it simply consists in signalling completion.
