Merge tag 'spi-v4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown: "Quite a lot of activity in SPI this cycle, almost all of it in drivers with a few minor improvements and tweaks in the core. - Updates to pxa2xx to support Intel Broxton and multiple chip selects. - Support for big endian in the bcm63xx driver. - Multiple slave support for the mt8173 - New driver for the auxiliary SPI controller in bcm2835 SoCs. - Support for Layerscale SoCs in the Freescale DSPI driver" * tag 'spi-v4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (87 commits) spi: pxa2xx: Rework self-initiated platform data creation for non-ACPI spi: pxa2xx: Add support for Intel Broxton spi: pxa2xx: Detect number of enabled Intel LPSS SPI chip select signals spi: pxa2xx: Add output control for multiple Intel LPSS chip selects spi: pxa2xx: Use LPSS prefix for defines that are Intel LPSS specific spi: Add DSPI support for layerscape family spi: ti-qspi: improve ->remove() callback spi/spi-xilinx: Fix race condition on last word read spi: Drop owner assignment from spi_drivers spi: Add THIS_MODULE to spi_driver in SPI core spi: Setup the master controller driver before setting the chipselect spi: dw: replace magic constant by DW_SPI_DR spi: mediatek: mt8173 spi multiple devices support spi: mediatek: handle controller_data in mtk_spi_setup spi: mediatek: remove mtk_spi_config spi: mediatek: Update document devicetree bindings to support multiple devices spi: fix kernel-doc warnings about missing return desc in spi.c spi: fix kernel-doc warnings about missing return desc in spi.h spi: pxa2xx: Align a few defines spi: pxa2xx: Save other reg_cs_ctrl bits when configuring chip select ...
