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/Makefile

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/Makefile
