[PATCH v4 8/8] DMA: Freescale: add suspend resume functions for DMA driver

From: Hongbo Zhang This patch adds suspend resume functions for Freescale DMA driver. .prepare callback is used to stop further descriptors from being added into the pending queue, and also issue pending queues into execution if there is any. .suspend callback makes sure all the pending jobs are

[PATCH v4 7/8] DMA: Freescale: use spin_lock_bh instead of spin_lock_irqsave

From: Hongbo Zhang The usage of spin_lock_irqsave() is a stronger locking mechanism than is required throughout the driver. The minimum locking required should be used instead. Interrupts will be turned off and context will be saved, it is unnecessary to use irqsave. This patch changes all insta
