Subject: SPI support for Sodaville
Date: Wed, 24 Nov 2010 12:13:18 +0100 [thread overview]
Message-ID: <1290597207-29838-1-git-send-email-bigeasy@linutronix.de> (raw)
The SPI core inside Sodaville is very much the same as in PXA25x.
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

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
