Let the dma/non-dma code paths handle the spi enable
flag themselves. This removes some logic to determine
if the flag should be turned on before or after dma
and also don't leave the spi enabled if the dma path

Hi,
I took another look at the rockchip spi driver and ended up
with more cleanups and implementing an interrupt handler
to fill/empty the tx and rx fifos rather than busy-looping.
I have two question though:
The driver sets the SPI_LOOP flag in master->mode_b
From: Emil Renner Berthing
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.

Successful transfers leave the spi disabled, so if

there should be no need to disable the spi from

Like other arch's we use patch_text_nosync or equivalent
to patch the jump-labels, but also like other arch's we

My hope is that we can eventually factor out the code to generate
