In k3 architecture a DMA channel (in TR momde) can be triggered by global
events, origination from different modules.
The events for triggers can be sent from any module which is connected to
PSI-L fabric, but the event number to be sent is DMA channel specific, it
is only known after the channel itself is requested.
The router operation needs to be split up:
- route_allocate: configure the dma_spec for the DMA and store the
configuration which is needed for the router's input
- set_event: callback used by the DMA driver to set the event number for
the channel and enable the routing

If the DMA device supports per channel coherency configuration (a channel

To better understand error that can be detected by the DMA controller,
manage the error flags before the transfer flags.
This way, it is possible to know if the FIFO error flag is set for an
over/underrun condition or a FIFO level error.
When a FIFO over/underrun condition occurs, the data is not lost because
peripheral request is not acknowledged by the stream until the over/
underrun condition is cleared. If this acknowledge takes too much time,
the peripheral itself may detect an over/underrun condition of its internal
buffer and data might be lost.
That's why in case the FIFO error flag is set, we check if the channel is
disabled or not, and if a Transfer Complete flag is set, which means that
the channel is disabled because of the end of transfer.
Because channel is disabled by hardware either by a FIFO level error, or by
an end of transfer.

Add a function to allow the affinity of an interrupt be switched to

This new interface has certain limitations, and attempts to use it in the
following circumstances will fail:
- For when the kernel is configured for generic IRQ reservation mode (in
config GENERIC_IRQ_RESERVATION_MODE). The reason being that it could
conflict with managed vs. non-managed interrupt accounting.
- The interrupt is already started, which should not be the case during
init
- The interrupt is already configured as managed, which means double init

We have two flavours of platform-MSI:
- MSIs generated by devices for themselves (the usual case)
- MSIs generated on behalf of other devices, as the generating
device is some form of bridge (either a wire-to-MSI bridge,
or even a non-transparent PCI bridge that repaints the PCI
requester ID).
In the latter case, the underlying interrupt architecture may need
to track this in order to keep the mapping alive even when no MSI
are currently being generated.
Add a set of flags to the generic msi_alloc_info_t structure, as
well as the MSI_ALLOC_FLAGS_PROXY_DEVICE flag that will get
advertized by the platform-MSI code when allocating an irqdomain
for a device.

ti_sci_intr_irq_domain_free() assumes that out_irq of intr is stored in
data->chip_data and uses it for calling ti_sci irq_free() and then
mark the out_irq as available resource. But ti_sci_intr_irq_domain_alloc()
is storing p_hwirq(parent's hardware irq) which is translated from out_irq.
This is causing resource leakage and eventually out_irq resources might
be exhausted. Fix ti_sci_intr_irq_domain_alloc() by storing the out_irq
