2012-03-30spi/mpc83xx: fix NULL pdata dereference bugKenth Eriksson
Commit 178db7d3, "spi: Fix device unregistration when unregistering the bus master", changed device initialization to be children of the bus master, not children of the bus masters parent device. The pdata pointer used in fsl_spi_chipselect must updated to reflect the changed initialization.

2011-09-23spi: Fix WARN when removing spi-fsl-spi moduleJeff Harris
If CPM mode is not used, the fsl_dummy_rx variable is never allocated. When the cleanup attempts to free it, the reference count is zero and a WARN is generated. The same CPM mode check used in the initialize is applied to the free as well. Tested on 2.6.33 with the previous spi_mpc8xxx driver. The renamed spi-fsl-spi driver looks to have the same problem.

2011-07-05spi/fsl_spi: fix CPM spi driverHolger Brunck
This patch fixes the freescale spi driver for CPM. Without this patch SPI on CPM failed because cpm_muram_alloc_fixed tries to allocate muram in an preserved area. The error reported was: mpc8xxx_spi f0011a80.spi: can't allocate spi parameter ram mpc8xxx_spi: probe of f0011a80.spi failed with error -12 Now the driver uses of_iomap to get access to this area similar to i2c driver driver in the i2c-cpm.c which has a similar device tree node. This is tested on a MPC8247 with CPM2. Signed-off-by: Holger Brunck <holger.brunck@keymile.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-06-06spi: reorganize driversGrant Likely
Sort the SPI makefile and enforce the naming convention spi_*.c for spi drivers. This change also rolls the contents of atmel_spi.h into the .c file since there is only one user of that particular include file. v2: - Use 'spi-' prefix instead of 'spi_' to match what seems to be be the predominant pattern for subsystem prefixes. - Clean up filenames in Kconfig and header comment blocks Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Wolfram Sang <w.sang@pengutronix.de> Acked-by: Linus Walleij <linus.walleij@linaro.org>
