* dmaengine: PL08x: move DMA signal muxing into pl08x_dma_chan structRussell King2012-07-01
| | | | | | | | | | Move the signal handling out of the physical channel structure into the virtual channel structure, where it should belong as it has more to do with the virtual channel than the physical one.

* dmaengine: PL08x: split DMA signal muxing from channel allocRussell King2012-07-01
| | | | | | | | | | | Split the DMA request mux signal handling from the physical channel allocation code. The physical channel has very little to do with the DMA request input which will be used, so these should be two separate operations.

| | | | | | | | | | | Ignore the direction argument in dma_slave_config, and configure both directions independently. We still check that the configuration for the intended direction is valid; this check will eventually be dropped. This check is just for debugging at present.

* dmaengine: PL08x: remove runtime PM supportRussell King2012-07-01
| | | | | | | | | | | | | | The runtime PM support conflicts with the generic AMBA bus PM, and also causes a potential deadlock with the PL011 driver as it results in interrupts being enabled beneath a spinlock.

* dmaengine: virt-dma: add support for cyclic DMA periodic callbacksRussell King2012-07-01
| | | | | | | | | | | | | Add support for cyclic DMA's periodic callbacks. Drivers are expected to call vchan_cyclic_callback() when a period has completed, which will schedule the tasklet to make the callback into the driver. As callbacks are made from tasklet context, it is important to realise that we don't guarantee a callback for each completed period, but for N completed periods where N may be greater than one.

This fix allows the kernel to boot without failure using a simple RAMDISK file system on OMAP4470 blaze board. Per feedback from Paul and Benoit the 4470 clock data is incomplete for new modules such as the 2D graphics block that has been added to the 4470. Therefore add a warning to indicate that the clock data is incomplete.

So add a quirk to ignore the irq0 overriding GSI 16 for the FUJITSU SIEMENS AMILO PRO V2030 platform will solve this issue.

This patch will extend acpi_skip_timer_override to cover all timer overriding cases as long as the source irq is 0.

The problem is that the isolated_cpus_lock mutex is owned when destroy_power_saving_task() calls kthread_stop(), which waits for a power_saving thread to end, and the power_saving thread tries to acquire the isolated_cpus_lock when it calls round_robin_cpu(). This patch fixes the issue by making round_robin_cpu() use its own mutex. https://bugzilla.kernel.org/show_bug.cgi?id=42981 Cc: stable@vger.kernel.org Signed-off-by: Stuart Hayes <Stuart_Hayes@Dell.com> Signed-off-by: Len Brown <len.brown@intel.com>
