https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git tags/spi-v5.2 for you to fetch changes up to 2e5f081003f033d37be3faf052aaccc8b6a44aa5: Merge branch 'spi-5.2' into spi-next (2019-05-02 11:20:29 +0900) ---------------------------------------------------------------- spi: Updates for v5.2 One small feature was added this release but the bulk of the diffstat and the changelog comes from the fact that several older drivers got some fairly hefty reworks and a couple of new drivers were added: - Support for detailed control of timing around chip selects from Sowjanya Komatineni. - A big set of fixes and imrovements for the Tegra114 driver from Sowjanya Komatineni. - A big simplification of the GPIO driver from Andrey Smirnov. - DMA support and fixes for the Freescale LPSPI driver from Clark Wang. - Fixes and optimizations for the bcm2835aux from Martin Sparl. - New drivers for Mediatek MT7621 (graduated from staging) and Zynq QSPI.
