Hi Chris,
I seem to have missed some tasklist manipulation in the execlist
selftest. Feel free to squash th
t properly
and set rx_work_tasklet.use_callback = true so that the callback is
called as
t->callback(t);
without all the casting.

The hardware supports 3 different variants of SPI
and there were some code around it, but nothing
to actually set it to anything but "Motorola SPI".
Just drop that code and always use that mode.

The state field is currently only used to make sure
only the last of the tx and rx dma callbacks issue
an spi_finalize_current_transfer.
Rather than using a spinlock we can get away
with just turning the state field into an atomic_t.

Just read transfer info directly from the spi device
and transfer structures rather than storing it in
driver data first.

The spi master (aka spi controller) structure already
has two fields for storing the rx and tx dma channels.
Just use them rather than duplicating them in driver data.

We only need to know if we're using dma when setting
up the transfer, so just use a local variable for
that.

The driver previously checked each transfer if the
requested speed was higher than possible with the
current spi clock rate and raised the clock rate
accordingly.
However, there is no check to see if the spi clock
was actually set that high and no way to dynamically
From: Emil Renner Berthing
In almost all cases we already have a pointer to the
spi master structure where we have the driver data.
The only exceptions are the dma callbacks which are
easily fixed by passing them the master and using
spi_master_get_devdata to retrieve the driver data.

The hardware supports 4, 8 and 16bit spi words,
so add the missing support for 4bit words.

Now that we no longer potentially change spi clock
at runtime we can precompute the rx sample delay
at probe time rather than for each transfer.

Successful transfers leave the spi disabled, so if
we just make sure to disable the spi on error
there should be no need to disable the spi from
master->unprepare_message.
This also flushes the tx and rx fifos,
so no need to do that manually.

Register an interrupt handler to fill/empty the
tx and rx fifos rather than busy-looping.
