dmaengine: imx-sdma: Add support for version 3 firmware

2015-03-18T08:23:33Z

Currently when version 3.1 of the mx6q SDMA firmware is used we get: [ 0.392169] imx-sdma 20ec000.sdma: unknown firmware version [ 0.399281] imx-sdma 20ec000.sdma: initialized Add support for it. Based on a patch from Shengjiu Wang from the internal FSL kernel. Signed-off-by: Fabio Estevam Signed-off-by: Vinod Koul

dmaengine: imx-sdma: switch to dynamic context mode after script loaded

2015-03-16T10:25:22Z

Below comments got from Page4724 of Reference Manual of i.mx6q: http://cache.freescale.com/files/32bit/doc/ref_manual/IMX6DQRM.pdf --"Static context mode should be used for the first channel called after reset to ensure that the all context RAM for that channel is initialized during the context SAVE phase when the channel is done or yields. Subsequent calls to the same channel or different channels may use any of the dynamic context modes. This will ensure that all context locations for the bootload channel are initialized, and prevent undefined values in context RAM from being loaded during the context restore if the channel is re-started later" Unfortunately, the rule was broken by commit(5b28aa319bba96987316425a1131813d87cbab35) .This patch just take them back.

dmaengine: imx-sdma: Return a proper error code in platform_get_irq()

2015-01-13T18:21:07Z

There is no need to return a 'fake' value upon platform_get_irq() failure. Just propagate the real error instead. Signed-off-by: Fabio Estevam Signed-off-by: Vinod Koul

dmaengine: imx-sdma: Use devm functions

2015-01-13T18:21:07Z

By using devm functions we can make the code shorter and cleaner. Signed-off-by: Fabio Estevam Signed-off-by: Vinod Koul
