Merge tag 'spi-v4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown: "This release is mainly a collection of driver specific updates, including a few nice cleanups to make drivers use more core features. - automatically use the parent device to allocate DMA buffers if there wasn't an explicitly configured device. - fixes for leaks on allocation. - a small piece of the start of SPI slave support, a feature that's been on the cards for over a decade!" * tag 'spi-v4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (55 commits) spi: spi-ti-qspi: Fix error handling spi: spi-ti-qspi: Fix error handling spi: lantiq-ssc: activate under COMPILE_TEST spi: armada-3700: Remove spi_master_put in a3700_spi_remove() spi: ti-qspi: revise ti_qspi_probe() failure flow spi: spi-ep93xx: simplify GPIO chip selects spi: rspi: Replaces "n" by "len" in qspi_transfer_*() spi: rspi: Fixes bogus received byte in qspi_transfer_in() spi: bcm-qspi: Remove unnecessary platform_set_drvdata() spi: bcm-qspi: Fix bcm_qspi_bspi_read() performance spi: lantiq-ssc: add support for Lantiq SSC SPI controller spi: s3c64xx: fix inconsistency between binding and driver spi: armada-3700: Remove .owner field for driver spi: bcm-qspi: Added mspi read fallback in bcm_qspi_flash_read() spi: fix device-node leaks spi: mediatek: Only do dma for 4-byte aligned buffers spi: When no dma_chan map buffers with spi_master's parent spi: pca2xx-pci: Allow MSI spi: pxa2xx: Prepare for edge-triggered interrupts spi: pxa2xx: Add support for Intel Gemini Lake ...
