I Cc the ARM folks because patch 4 reorganizes some files so that they can be accessed from x86 so you see the whole picture. Yes, Sodaville is a x86 SoC :) The SPI device is behind a PCI bus. The PCI probe code simply creates a platform device so we don't have much changes to the platform driver. I tried to avoid as much ifdefs as possible. There is no clock framework on x86 and the peripherals don't support changing their clocks or to enable/disable them. So I provided dummy function which keep the driver happy. The patch series has been created with the -M option so file moves can be easily noticed. The whole series is also available at git://git.linutronix.de/users/bigeasy/soda.git spi Sebastian Andrzej Siewior (9): spi/pxa2xx: don't use subys initcall for driver init spi/pxa2xx: add support for shared IRQ handler spi/pxa2xx: Use define for SSSR_TFL_MASK instead of plain numbers arm/pxa2xx: reorgazine SSP and SPI header files spi/pxa2xx: Add CE4100 support spi/pxa2xx: Consider CE4100's FIFO depth spi/pxa2xx: Add chipselect support for Sodaville spi/pxa2xx: Modify RX-Tresh instead of busy-loop for the remaining RX bytes. spi/pxa2xx: pass of_node to spi device and set a parent device Documentation/spi/pxa2xx | 4 +- arch/arm/include/asm/pxa2xx_ssp.h | 15 ++ arch/arm/mach-pxa/cm-x255.c | 2 +- arch/arm/mach-pxa/cm-x270.c | 2 +- arch/arm/mach-pxa/corgi.c | 2 +- arch/arm/mach-pxa/devices.c | 2 +- arch/arm/mach-pxa/em-x270.c | 2 +- arch/arm/mach-pxa/hx4700.c | 2 +- arch/arm/mach-pxa/icontrol.c | 2 +- arch/arm/mach-pxa/littleton.c | 2 +- arch/arm/mach-pxa/lubbock.c | 2 +- arch/arm/mach-pxa/pcm027.c | 2 +- arch/arm/mach-pxa/poodle.c | 2 +- arch/arm/mach-pxa/spitz.c | 3 +- arch/arm/mach-pxa/stargate2.c | 2 +- arch/arm/mach-pxa/tosa.c | 2 +- arch/arm/mach-pxa/trizeps4.c | 1 - arch/arm/mach-pxa/z2.c | 2 +- arch/arm/mach-pxa/zeus.c | 2 +- arch/arm/plat-pxa/ssp.c | 2 +- arch/x86/include/asm/pxa2xx_spi_ce4100.h | 99 ++++++++++ arch/x86/include/asm/pxa2xx_ssp.h | 15 ++ drivers/spi/Kconfig | 15 +- drivers/spi/Makefile | 1 + drivers/spi/pxa2xx_spi.c | 185 +++++++++++++------ drivers/spi/pxa2xx_spi_pci.c | 201 ++++++++++++++++++++ .../plat/ssp.h => include/linux/pxa2xx_ssp.h | 16 +- .../mach => include/linux/spi}/pxa2xx_spi.h | 16 ++- sound/soc/pxa/pxa-ssp.c | 2 +- 29 files changed, 512 insertions(+), 93 deletions(-) create mode 100644 arch/arm/include/asm/pxa2xx_ssp.h create mode 100644 arch/x86/include/asm/pxa2xx_spi_ce4100.h create mode 100644 arch/x86/include/asm/pxa2xx_ssp.h create mode 100644 drivers/spi/pxa2xx_spi_pci.c rename arch/arm/plat-pxa/include/plat/ssp.h => include/linux/pxa2xx_ssp.h (95%) rename {arch/arm/mach-pxa/include/mach => include/linux/spi}/pxa2xx_spi.h (86%) Sebastian
