2011-05-13dmaengine/dw_dmac: Replace spin_lock* with irqsave variants and enable ↵Viresh Kumar
submission from callback dmaengine routines can be called from interrupt context and with interrupts disabled. Whereas spin_unlock_bh can't be called from such contexts. So this patch converts all spin_*_bh routines to irqsave variants. Also, spin_lock() used in tasklet is converted to irqsave variants, as tasklet can be interrupted, and dma requests from such interruptions may also call spin_lock. Now, submission from callbacks are permitted as per dmaengine framework. So we shouldn't hold any locks while calling callbacks. As locks were taken by parent routines, so releasing them before calling callbacks doesn't look clean enough. So, locks are taken inside all routine now, whereever they are required. And dwc_descriptor_complete is always called without taking locks. Signed-off-by: Viresh Kumar <viresh.kumar@st.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>

2011-05-12dmaengine: at_hdmac: pause: no need to wait for FIFO emptyNicolas Ferre
With the addition of the "pause" feature, an active wait was introduced to check the "FIFO empty" event. This event was not always happening and a timout contition was needed. But, in some cases, this event depend on the peripheral connected to the channel that is paused: FIFO becomes empty if the peripheral consumes data. The timeout is pretty difficult to evaluate. Moreover, this check is not needed. In conclusion, it seems sensible to entirely remove the checking of "FIFO empty" status when pausing.
