ARM: pxa: remove platform dma code

2016-08-09T06:16:58Z

As the last pxa related driver was converted to dmaengine, it's time to kill the legacy dma code, which is not used anymore. This finishes the pxa dmaengine transition. Signed-off-by: Robert Jarzmik

ARM: pxa: add the number of DMA requestor lines

2016-02-26T21:57:05Z

Declare the number of DMA requestor lines per platform : - for pxa25x: 40 requestor lines - for pxa27x: 75 requestor lines - for pxa3xx: 100 requestor lines This information will be used to activate the DMA flow control or not. Signed-off-by: Robert Jarzmik

ARM: mmp: move into ARCH_MULTIPLATFORM

2015-12-01T20:44:31Z

With all dependencies taken care of, this enables building the Marvell mmp platform as part of ARCH_MULTIPLATFORM, along with other ARMv5 and ARMv7 platforms. Signed-off-by: Arnd Bergmann Acked-by: Andrew Lunn

ARM: mmp: make plat-pxa build standalone

2015-12-01T20:44:28Z

The ssp.c driver in plat-pxa is the only remaining file including a mach/*.h header from mmp. It actually doesn't need mach/hardware.h at all, so we can remove the #include. Signed-off-by: Arnd Bergmann

ARM: mmp: remove remaining legacy pxa-dma support

2015-12-01T20:44:27Z

All drivers have stopped using this code, so we can just as well stop initializing it. Signed-off-by: Arnd Bergmann

ARM: pxa: ssp: Fix build error by removing originally incorrect DT binding

2015-09-13T10:55:27Z

Commit 03fbf488cece ("spi: pxa2xx: Differentiate Intel LPSS types") caused build error here because it removed the type LPSS_SSP and I didn't notice the type was used here too. I believe commit a6e56c28a178 ("ARM: pxa: ssp: add DT bindings") added it accidentally by copying all enum pxa_ssp_type types from include/linux/pxa2xx_ssp.h even LPSS_SSP was for Intel LPSS SPI devices. Fix the build error by removing this incorrect binding.

ARM: pxa: transition to dmaengine phase 1

2015-07-18T10:16:33Z

In order to slowly transition pxa to dmaengine, the legacy code will now rely on dmaengine to request a channel. This implies that PXA architecture selects DMADEVICES and PXA_DMA, which is not pretty. Yet it enables PXA drivers to be ported one by one, with part of them using dmaengine, and the other part using the legacy code. Signed-off-by: Robert Jarzmik

ARM: plat-pxa: remove use of seq_printf return value

2015-04-15T23:35:25Z

The seq_printf return value, because it's frequently misused, (as it is here, it doesn't return # of chars emitted) will eventually be converted to void. See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to seq_has_overflowed() and make public") Signed-off-by: Joe Perches Cc: Russell King Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

ARM: plat-pxa: drop owner assignment from platform_drivers

2014-10-20T14:20:07Z

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

ARM: pxa: ssp: provide platform_device_id for PXA3xx

2014-09-18T17:56:02Z

Provide an explicit match string for PXA3xx SSP ports. Without this match string, SSP0/SSP1/SSP2 in PXA3xxx will be consided as PXA27x SSP Port. Signed-off-by: Daniel Mack Signed-off-by: Haojian Zhuang
