The following changes since commit 54be6c6c5ae8e0d93a6c4641cb7528eb0b6ba478: Linux 6.8-rc3 (2024-02-04 12:20:36 +0000) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git tags/spi-v6.9 for you to fetch changes up to be84be4a35fa99cca7e81e6dd21516a324cca413: spi: Introduce SPI_INVALID_CS and is_valid_cs() (2024-03-07 15:07:11 +0000) ---------------------------------------------------------------- spi: Updates for v6.9 This release sees some exciting changes from David Lechner which implements some optimisations that have been talked about for a long time which allows client drivers to pre-prepare SPI messages for repeated or low latency use. This lets us move work out of latency sensitive paths and avoid repeating work for frequently performed operations. As well as being useful in itself this will also be used in future to allow controllers to directly trigger SPI operations (eg, from interrupts). Otherwise this release has mostly been focused on cleanups, plus a couple of new devices: - Support for pre-optimising messages. - A big set of updates from Uwe Kleine-König moving drivers to use APIs with more modern terminology for controllers. - Major overhaul of the s3c64xx driver. - Support for Google GS101 and Samsung Exynos850. ----------------------------------------------------------------
