Merge tag 'spi-v4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown: "A fairly quiet release for the SPI subsystem: - Move to using IDR for allocating bus numbers - Modernisation of the ep93xx driver, removing a lot of open coding and using the framework more - The tools have been moved to use the standard tools build system and an install target added (there will be a fairly trivial conflict with tip resulting from the changes in the main tools Makefile) - A refactoring of the Qualcomm QUP driver which enables new variants to be supported - Explicit support for the Freescale i.MX53 and i.MX6 SPI, Renesas R-Car H3 and Rockchip RV1108 controllers" * tag 'spi-v4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (71 commits) spi: spi-falcon: drop check of boot select spi: imx: fix use of native chip-selects with devicetree spi: pl022: constify amba_id spi: imx: fix little-endian build spi: omap: Allocate bus number from spi framework spi: Kernel coding style fixes spi: imx: dynamic burst length adjust for PIO mode spi: Pick spi bus number from Linux idr or spi alias spi: rockchip: configure CTRLR1 according to size and data frame spi: altera: Consolidate TX/RX data register access spi: altera: Switch to SPI core transfer queue management spi: rockchip: add compatible string for rv1108 spi spi: qup: fix 64-bit build warning spi: qup: hide warning for uninitialized variable spi: spi-ep93xx: use the default master transfer queueing mechanism spi: spi-ep93xx: remove private data 'current_msg' spi: spi-ep93xx: pass the spi_master pointer around spi: spi-ep93xx: absorb the interrupt enable/disable helpers spi: spi-ep93xx: add spi master prepare_transfer_hardware() spi: spi-ep93xx: use 32-bit read/write for all registers ...
