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. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmXvHx0ACgkQJNaLcl1U h9ATVQf/WafEp7ddJ23bRaHZx/gBCMgv8N6mN7OBnzB2pMIGL56SPf9fGAmCUQKt mne6fDg6/RpydG/72TFppUjRFLN9CwoJjJfQIXMgOqYuPaMEnrj1wbcXar3MeeX2 8hS1u7wKwhOuuwLmoqqMOTKyGUj2mHsBOTOo0vm4WM1s9IHhY5TG2clYv1A+KZbj kSHE5m7YnBLwimwu0+hsXnRNHZUGKVksQ/9t7AD7/7L8aPj9jPqu1EjTS1/6IDB0 QDVyW7Z6hX7YoUx48gp+j/UFJ7ZyxTajy+0wvzPHou3KJARgFfNZWT2XvvYcpA0/ yqcpbCUwZ1AETXHcmly7YwNpPV9LBg== =+Xw/ -----END PGP SIGNATURE----- Merge tag 'spi-v6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi updates from Mark Brown: "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.
