* dmaengine: at_hdmac: pause: no need to wait for FIFO emptyNicolas Ferre2011-05-121-16/+0
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | also with llp dwc_scan_descriptors scans all descriptors from active_list in case transfer is not completed. It compares first_desc->lli.llp, and then all childrens of its tx_list. But it doesn't compare its own address, i.e. first_desc->txd.phys, as this is what we have initially programmed into the controller register. So this causes dma to stop and finish a transfer, which was never started. And thus fail. Signed-off-by: Viresh Kumar <viresh.kumar@st.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>

These IP cores are included in many multifunction devices, in sh-mobile chips from Renesas, in the latter case they can also use DMA. Some sh-mobile implementations also have some other specialities, that MFD-based solutions don't have. This makes supporting all these features in a monolithic driver inconveniet and error-prone. This patch splits the driver into 3 parts: the core, the MFD glue and the DMA support. In case of a modular build, two modules will be built: mmc_tmio_core and mmc_tmio.
