The following changes since commit 7566ec393f4161572ba6f11ad5171fd5d59b0fbd: Linux 4.20-rc7 (2018-12-16 15:46:55 -0800) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git tags/spi-v4.21 for you to fetch changes up to 74ff666bd7ba2da563f99f2a8af7bf9f20008bc9: Merge remote-tracking branches 'spi/topic/mem' and 'spi/topic/mtd' into spi-next (2018-12-20 16:01:30 +0000) ---------------------------------------------------------------- spi: Updates for v4.21 The main thing this release has been a lot of work on the integration with SPI NOR flashes, there's been some specific support for a while for controller features designed to make them perform better but it's not worked out as well as hoped so the interface has been redesigned in a way that will hopefully do better - it's already been adopted by a number of additional controllers so things are looking good. Otherwise most of the work has been driver specific: - Support for better integration with NOR flashes from Boris Brezillon and Yogesh Narayan Gaur plus usage of it in several drivers. - A big cleanup of the Rockchip driver from Emil Renner Berthing. - Lots of performance improvements for bcm2835 from Lukas Wunner. - Slave mode support for pxa2xx from Lubomir Rintel. - Support for Macronix MXIC, Mediatek MT7629 and MT8183, NPCM PSPI, and Renesas r8a77470. ---------------------------------------------------------------- Alok Chauhan (2): spi: spi-geni-qcom: fix nitpicks spi: spi-geni-qcom: Simplify probe function Arnd Bergmann (1): mtd: atmel-quadspi: disallow building on ebsa110 Boris Brezillon (4): spi: spi-mem: Add missing word in the SPI_MEM_DATA_OUT description spi: spi-mem: Add SPI_MEM_NO_DATA to the spi_mem_data_dir enum spi: spi-mem: Split spi_mem_exec_op() code spi: spi-mem: Add a new API to support direct mapping Chuanhua Han (1): spi: spi-fsl-dspi: use IRQF_SHARED mode to request IRQ Clark Wang (4): spi: lpspi: Replace all "master" with "controller" spi: lpspi: Add slave mode support spi: lpspi: Let watermark change with send data length doc: lpspi: Document DT bindings for LPSPI slave mode Colin Ian King (1): spi: npcm: fix u32 csgpio being checked for less than zero Dan Carpenter (1): spi: npcm: Fix an error code in the probe function Emil Renner Berthing (14): spi: rockchip: make spi_enable_chip take bool spi: rockchip: use designated init for dma config spi: rockchip: always use SPI mode spi: rockchip: use atomic_t state spi: rockchip: disable spi on error spi: rockchip: read transfer info directly spi: rockchip: don't store dma channels twice spi: rockchip: remove master pointer from dev data spi: rockchip: simplify use_dma logic spi: rockchip: set min/max speed spi: rockchip: precompute rx sample delay spi: rockchip: use irq rather than polling spi: rockchip: support 4bit words spi: rockchip: support lsb-first mode Fabrizio Castro (2): spi: rspi: Add r8a77470 to the compatible list spi: sh-msiof: Add r8a774c0 support Fredrik Ternerot (1): spi: pl022: Handle cs_change for last transfer Hoan Nguyen An (1): spi: sh-msiof: Reduce the number of times write to and perform the transmission from FIFO Jarkko Nikula (1): spi: pxa2xx: Remove LPSS private register restoring during resume Jay Fang (1): spi: dw-mmio: add ACPI support Keiji Hayashibara (2): spi: uniphier: fix incorrect property items spi: uniphier: re-add addressing properties Leilk Liu (4): spi: mediatek: Add bindings for mediatek MT8183 soc platform spi: mediatek: add spi support for mt8183 IC spi: mediatek: Add bindings for mediatek MT7629 soc platform spi: mediatek: add spi support for mt7629 IC Linus Walleij (1): spi: gpio: Support 3WIRE high-impedance turn-around Lubomir Rintel (7): spi: pxa2xx: dt-bindings: Add spi-slave property spi: Deal with slaves that return from transfer_one() unfinished spi: pxa2xx: Add slave mode support spi: pxa2xx: dt-bindings: Add ready GPIO signal spi: pxa2xx: Add ready signal spi: pxa2xx: Deal with the leftover garbage in TXFIFO spi: pxa2xx: Fix '"CONFIG_OF" is not defined' warning Lukas Wunner (10): spi: bcm2835: Avoid finishing transfer prematurely in IRQ mode spi: bcm2835: Fix book-keeping of DMA termination spi: bcm2835: Fix race on DMA termination spi: bcm2835: Drop unused code for native Chip Select spi: bcm2835: Document struct bcm2835_spi spi: bcm2835: Overcome sglist entry length limitation spi: bcm2835: Unbreak the build of esoteric configs spi: bcm2835: Polish transfer of DMA prologue spi: bcm2835: Speed up FIFO access if fill level is known spi: bcm2835: Synchronize with callback on DMA termination Mark Brown (9): Merge branch 'spi-4.20' into spi-4.21 for uniphier DT spi: Fix core transfer waits after slave support Merge branch 'spi-4.20' into spi-4.21 for bcm stuff.
