Subject: [PATCH 0/2] DMA: PL330: Clock and runtime cleanup

The controller clock is being managed at AMBA bus level probe/remove and
pm_runtime/suspend functions. The existing driver does the clock enable/disable
again in the same code paths, which unneccessarily increments the usage count of
the clock for the same device. 

The following patches remove the redundant clock enable/disable from the driver.

Inderpal Singh (2):
  DMA: PL330: Remove controller clock enable/disable
  DMA: PL330: Remove redundant runtime_suspend/resume functions
