d32c4e58 - spi: SPI_QPIC_SNAND should be tristate and depend on MTD

Wed, 26 Mar 2025 14:22:19 +0000

spi: SPI_QPIC_SNAND should be tristate and depend on MTDSPI_QPIC_SNAND is the only driver that selects MTD instead of dependingon it, which could lead to circular dependencies. Moreover, asSPI_QPIC_SNAND is bool, this forces MTD (and various related symbols) tobe built-in, as can be seen in an allmodconfig kernel.Except for a missing semicolon, there is no reason why SPI_QPIC_SNANDcannot be tristate; all MODULE_*() boilerplate is already present.Hence make SPI_QPIC_SNAND tristate, let it depend on MTD, and add themissing semicolon.Fixes: 7304d1909080ef0c ("spi: spi-qpic: add driver for QCOM SPI NAND flash Interface")Signed-off-by: Geert Uytterhoeven Link: https://patch.msgid.link/b63db431cbf35223a4400e44c296293d32c4543c.1742998909.git.geert+renesas@glider.beSigned-off-by: Mark Brown List of files: /linux-6.15/drivers/spi/Kconfig

spi: axi-spi-engine: implement offload supportImplement SPI offload support for the AXI SPI Engine. Currently, thehardware only supports triggering offload transfers with a hardwaretrigger so attempting to use an offload message in the regular SPImessage queue will fail. Also, only allows streaming rx data to anexternal sink, so attempts to use a rx_buf in the offload message willfail.Reviewed-by: Jonathan Cameron Reviewed-by: Nuno Sa Signed-off-by: David Lechner Link: https://patch.msgid.link/20250207-dlech-mainline-spi-engine-offload-2-v8-7-e48a489be48c@baylibre.comSigned-off-by: Mark Brown List of files: /linux-6.15/drivers/spi/Kconfig

8e02d188 - spi: add basic support for SPI offloading

Fri, 07 Feb 2025 20:08:58 +0000

spi: add basic support for SPI offloadingAdd the basic infrastructure to support SPI offload providers andconsumers.SPI offloading is a feature that allows the SPI controller to performtransfers without any CPU intervention. This is useful, e.g. forhigh-speed data acquisition.SPI controllers with offload support need to implement the get_offloadand put_offload callbacks and can use the devm_spi_offload_alloc() toallocate offload instances.SPI peripheral drivers will call devm_spi_offload_get() to get areference to the matching offload instance. This offload instance canthen be attached to a SPI message to request offloading that message.It is expected that SPI controllers with offload support will check forthe offload instance in the SPI message in the ctlr->optimize_message()callback and handle it accordingly.CONFIG_SPI_OFFLOAD is intended to be a select-only option. Bothconsumer and provider drivers should `select SPI_OFFLOAD` in theirKconfig to ensure that the SPI core is built with offload support.Reviewed-by: Jonathan Cameron Reviewed-by: Nuno Sa Signed-off-by: David Lechner Link: https://patch.msgid.link/20250207-dlech-mainline-spi-engine-offload-2-v8-1-e48a489be48c@baylibre.comSigned-off-by: Mark Brown List of files: /linux-6.15/drivers/spi/Kconfig

c36212b2 - spi: apple: Add driver for Apple SPI controller

Wed, 06 Nov 2024 07:54:01 +0000

spi: apple: Add driver for Apple SPI controllerThis SPI controller is present in Apple SoCs such as the M1 (t8103) andM1 Pro/Max (t600x). It is a relatively straightforward design with two16-entry FIFOs, arbitrary transfer sizes (up to 2**32 - 1) and fullyconfigurable word size up to 32 bits. It supports one hardware CS linewhich can also be driven via the pinctrl/GPIO driver instead, ifdesired. TX and RX can be independently enabled.There are a surprising number of knobs for tweaking details of thetransfer, most of which we do not use right now. Hardware CS controlis available, but we haven't found a way to make it stay low acrossmultiple logical transfers, so we just use software CS control for now.There is also a shared DMA offload coprocessor that can be used to handlelarger transfers without requiring an IRQ every 8-16 words, but thatfeature depends on a bunch of scaffolding that isn't ready to beupstreamed yet, so leave it for later.The hardware shares some register bit definitions with spi-s3c24xx whichsuggests it has a shared legacy with Samsung SoCs, but it is toodifferent to warrant sharing a driver.Signed-off-by: Hector Martin Signed-off-by: Janne Grunau Link: https://patch.msgid.link/20241106-asahi-spi-v5-2-e81a4f3a8e19@jannau.netSigned-off-by: Mark Brown List of files: /linux-6.15/drivers/spi/Kconfig

spi: cs42l43: Add bridged cs35l56 amplifiersOn some cs42l43 systems a couple of cs35l56 amplifiers are attachedto the cs42l43's SPI and I2S. On Windows the cs42l43 is controlledby a SDCA class driver and these two amplifiers are controlled byfirmware running on the cs42l43. However, under Linux the decisionwas made to interact with the cs42l43 directly, affording the usergreater control over the audio system. However, this has resultedin an issue where these two bridged cs35l56 amplifiers are notpopulated in ACPI and must be added manually.Check for the presence of the "01fa-cirrus-sidecar-instances" propertyin the SDCA extension unit's ACPI properties to confirm the presenceof these two amplifiers and if they exist add them manually onto theSPI bus.Reviewed-by: Andy Shevchenko Signed-off-by: Maciej Strozek Signed-off-by: Charles Keepax Link: https://lore.kernel.org/r/20240416100904.3738093-5-ckeepax@opensource.cirrus.comSigned-off-by: Mark Brown List of files: /linux-6.15/drivers/spi/Kconfig
