ARM: pxa: ssp: Check return values from phandle lookups

2013-09-10T00:14:09+00:00

Commit a6e56c28a178cef5f (ARM: pxa: ssp: add DT bindings) causes warnings when built: arch/arm/plat-pxa/ssp.c: In function 'pxa_ssp_probe': arch/arm/plat-pxa/ssp.c:145:17: warning: 'dma_spec.args[0]' may be used uninitialized in this function [-Wmaybe-uninitialized] Resolve by checking return values and aborting when lookups fail.

ARM: pxa: ssp: add pxa_ssp_request_of()

2013-08-14T18:54:30+00:00

Add a function to lookup ssp devices from device tree. This way, users can reference the ssp devices in order to register to them. Signed-off-by: Daniel Mack Acked-by: Haojian Zhuang Signed-off-by: Mark Brown

ARM: pxa: ssp: use devm_ functions

2013-08-14T18:54:27+00:00

Use devm_ functions to allocate memory, ioremap, clk_get etc to clean up the error unwind path. Signed-off-by: Daniel Mack Acked-by: Haojian Zhuang Signed-off-by: Mark Brown

ARM: pxa: ssp: add DT bindings

2013-08-14T18:54:23+00:00

This patch contains an ugly hack for looking up the the DMA request number. The problem here is that the implementation as it stands will allocate the DMA channel from the user of the ssp port, and hence we cannot allocate a real channel here.

ARM: pxa: ssp: add shortcut for &pdev->dev

2013-08-14T18:54:20+00:00

No functional change, just a cosmetic cleanup. Signed-off-by: Daniel Mack Acked-by: Haojian Zhuang Signed-off-by: Mark Brown

ARM: pxa: ssp: remove unnecessary warning on kzalloc() failure

2013-08-14T18:54:12+00:00

The memory subsystem will already complain loudly enough in such cases. Signed-off-by: Daniel Mack Acked-by: Haojian Zhuang Signed-off-by: Mark Brown

ARM: drivers: remove __dev* attributes.

2013-01-03T23:57:04+00:00

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

ARM: MMP: add pxa910-ssp into ssp_id_table

add pxa910-ssp into ssp_id_table, and fix pxa-ssp compiling issue under mach-mmp architect. Signed-off-by: Qiao Zhou Acked-by: Haojian Zhuang Signed-off-by: Mark Brown

arm/pxa2xx: reorgazine SSP and SPI header files

2010-12-01T11:18:33+00:00

The PXA-SPI driver relies on some files / defines which are arm specific and are within the ARM tree. The CE4100 SoC which is x86 has also the SPI core. This patch moves the ssp and spi files from arm/mach-pxa and plat-pxa to include/linux where the CE4100 can access them. This move got verified by building the following defconfigs: cm_x2xx_defconfig corgi_defconfig em_x270_defconfig ezx_defconfig imote2_defconfig pxa3xx_defconfig spitz_defconfig zeus_defconfig raumfeld_defconfig magician_defconfig Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Dirk Brandewie

[ARM] pxa: add namespace on ssp

In order to prevent code ambiguous, add namespace on functions in ssp driver. Signed-off-by: Haojian Zhuang Acked-by: Liam Girdwood Signed-off-by: Eric Miao
