dmaengine: qcom_hidma: use for_each_matching_node() macro

2016-07-24T06:16:05Z

dmaengine: qcom_hidma_lli: kill the tasklets upon exit

drivers should ensure that tasklets are killed, so that they can't be run after driver remove is executed Signed-off-by: Vinod Koul Cc: Sinan Kaya

dmaengine: qcom_hidma: fix return value check in hidma_mgmt_of_populate_channels()

2016-07-12T04:44:41Z

In case of error, the function platform_device_register_full() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Signed-off-by: Wei Yongjun Signed-off-by: Vinod Koul

dmaengine: qcom-bam-dma: add __maybe_unused annotations for PM

2016-07-06T17:09:43Z

The bam_dma driver gained runtime PM support, but that causes build warnings whenever CONFIG_PM is disabled: drivers/dma/qcom/bam_dma.c:1324:12: error: 'bam_dma_runtime_resume' defined but not used [-Werror=unused-function] static int bam_dma_runtime_resume(struct device *dev) ^~~~~~~~~~~~~~~~~~~~~~ drivers/dma/qcom/bam_dma.c:1315:12: error: 'bam_dma_runtime_suspend' defined but not used [-Werror=unused-function] static int bam_dma_runtime_suspend(struct device *dev) This removes the incomplete #ifdef guard and instead marks all four PM functions as __maybe_unused, which avoids this kind of warning.

dmaengine: qcom-bam-dma: Add pm_runtime support

2016-06-30T04:35:56Z

Adds pm_runtime support for BAM DMA so that clock is enabled only when there is a transaction going on to help save power. Signed-off-by: Pramod Gurav Signed-off-by: Vinod Koul

dmaengine: qcom_hidma: add support for object hierarchy

2016-05-14T06:24:45Z

In order to create a relationship model between the channels and the management object, we are adding support for object hierarchy to the drivers. This patch simplifies the userspace application development. We will not have to traverse different firmware paths based on device tree or ACPI based kernels. No matter what flavor of kernel is used, objects will be represented as platform devices. The new layout is as follows: hidmam_10: hidma-mgmt@0x5A000000 { compatible = "qcom,hidma-mgmt-1.0"; ... hidma_10: hidma@0x5a010000 { compatible = "qcom,hidma-1.0"; ... } } The hidma_mgmt_init detects each instance of the hidma-mgmt-1.0 objects in device tree and calls into the channel driver to create platform devices for each child of the management object.

dmaengine: qcom_hidma: add debugfs hooks

2016-05-14T06:24:45Z

Add debugfs hooks for debugging the execution behavior of the DMA channel. The debugfs hooks get initialized by the probe function and uninitialized by the remove function. A stats file is created in debugfs. The stats file will show the information about each HIDMA channel as well as each asynchronous job queued and completed at a given time.
