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 ...

2015-10-28spi: Drop owner assignment from spi_driversAndrew F. Davis1-1/+0
An spi_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Andrew F. Davis <afd@ti.com> Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Mark Brown <broonie@kernel.org>

We want the staging fixes in here as well. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2015-09-13staging: fbtft: fix 9-bit SPI support detectionStefan Wahren1-7/+4
Since the result of the setup function isn't adequate to check 9-bit SPI support, we better check bits_per_word_mask. Btw this change avoids a NULL pointer dereference with master drivers without a separate setup function.

2015-09-12staging/fbtft : Remove repeated set_addr_win debug messagesAnish Bhatt1-10/+0
fbtft_par_dbg(DEBUG_SET_ADDR_WIN.. ) is repeated in every set_addr_win() handler, this could be replicated by using the kernel function tracer instead.

2015-08-07Staging: fbtft: Use a struct to describe each LCD controllerFabio Falzoi1-96/+136
Use a struct flexfb_lcd_controller to holds chip properties, instead of relying on a long 'if - else if' chain. This allows to: - use a simple linear search to verify if a certain LCD controller model is supported or not. - add support for a new LCD chip controller simply defining a new flexfb_lcd_controller struct.

2015-08-03staging: fbtft: core: Don't set device platform_dataNoralf Trønnes1-1/+1
Pass platform_data as an argument to fbtft_framebuffer_alloc() instead of using dev->platform_data. This fixes an issue where the device comes from Device Tree and fbtft_probe_common() sets dev->platform_data to allocated memory. When the module is reloaded, dev->platform_data points to freed memory. Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
