* spi: fsl-(e)spi: migrate to generic master queueingHeiner Kallweit2014-12-031-9/+1
| | | | | | | | Migrates the fsl-(e)spi driver to use the generic master queuing. Avoids the "master is unqueued, this is deprecated" warning. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
* spi: fsl: Kill mpc8xxx_spi_cleanup and convert fsl_espi_setup to use ↵Axel Lin2014-04-141-1/+0
| | | | | | | | | | | | | | | devm_kzalloc In current code, master->cleanup and master->setup are not set in the same function. This makes it hard to read and not good for code maintain. One example is in fsl-spi.c, master->cleanup is overrided in mpc8xxx_spi_probe() which leads to a memory leak. This patch removes mpc8xxx_spi_cleanup() and converts fsl_espi_setup to use devm_kzalloc so we don't need to take care of freeing memory.

* spi/spi-fsl-spi: Make driver usable in CPU mode outside of an FSL_SOC ↵Andreas Larsson2013-04-071-2/+4
| | | | | | | | | | | | | | | | environment This makes the spi-fsl-spi driver usable in CPU mode outside of an FSL_SOC and even an powerpc environment by moving CPM mode functionality to a separate file that is only compiled and linked in an FSL_SOC environment and adding some ifdefs to hide types and functions or provide alternatives. For devicetree probing a "clock-frequency" property is used for clock frequency instead of calls to FSL_SOC-specific functions.

* spi: reorganize driversGrant Likely2011-06-061-0/+123
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>
