2015-01-13dmaengine: k3: fix duplicate function definitionArnd Bergmann1-3/+3
Commit db08425ebd51f ("dmaengine: k3: Split device_control") introduced two new helper functions, which unfortunately have the same names as the existing suspend/resume functions, resulting in a build error when CONFIG_PM_SLEEP is enabled: drivers/dma/k3dma.c:823:12: error: conflicting types for 'k3_dma_resume' static int k3_dma_resume(struct device *dev) ^ drivers/dma/k3dma.c:625:12: note: previous definition of 'k3_dma_resume' was here static int k3_dma_resume(struct dma_chan *chan) ^ Signed-off-by: Arnd Bergmann <arnd@arndb.de> Fixes: db08425ebd51f ("dmaengine: k3: Split device_control") Reported-by: Mark Brown <broonie@kernel.org> Signed-off-by: Vinod Koul <vinod.koul@intel.com>

While splitting device control in db08425ebd51 ("dmaengine: k3: Split device_control") new function with the same 'k3_dma_resume' name was added, leading to build error: drivers/dma/k3dma.c:823:12: error: conflicting types for ‘k3_dma_resume’ drivers/dma/k3dma.c:625:12: note: previous definition of ‘k3_dma_resume’ was here Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
2014-12-22dmaengine: k3: Split device_controlMaxime Ripard1-90/+107
Split the device_control callback of the Hisilicon K3 DMA driver to make use of the newly introduced callbacks, that will eventually be used to retrieve slave capabilities. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
2014-11-17dmaengine: k3dma: Add CONFIG_PM_SLEEP to suspend/resume functionsJingoo Han1-0/+2
Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following build warning when CONFIG_PM_SLEEP is not selected. This is because sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when the CONFIG_PM_SLEEP is enabled. drivers/dma/k3dma.c:790:12: warning: 'k3_dma_suspend' defined but not used [-Wunused-function] drivers/dma/k3dma.c:806:12: warning: 'k3_dma_resume' defined but not used [-Wunused-function] Signed-off-by: Jingoo Han <jg1.han@samsung.com> Acked-by: Zhangfei Gao <zhangfei.gao@linaro.org> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
2014-11-06dmaengine: Remove .owner field for driverKiran Padwal1-1/+0
There is no need to init .owner field. Based on the patch from Peter Griffin <peter.griffin@linaro.org> "mmc: remove .owner field for drivers using module_platform_driver" This patch removes the superflous .owner field for drivers which use the module_platform_driver API, as this is overriden in platform_driver_register anyway."

2014-11-06dmaengine: k3: Remove chancnt affectationsMaxime Ripard1-1/+0
chanctnt is already filled by dma_async_device_register, which uses the channel list to know how much channels there is. Since it's already filled, we can safely remove it from the drivers' probe function. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
