GPIO control register is divided into IOPINS1 and IOPINS2.
And low 4-bit of register is controls output.
So, this patch fixes wrong mask of GPIO output.

An spi_driver does not need to set an owner, it will be populated by the

To be future-proof and for better readability the time comparisons are
modified to use time_after() instead of plain, error-prone math.

As far as kzalloc() is called with spinlock held,
we have to pass GFP_ATOMIC regardless of mem_flags argument.

kmalloc the SPI rx and tx data buffers. This appears to be the only
portable way to guarantee that the buffers are DMA-safe (e.g., in
separate DMA cache-lines). This patch makes the spi_rdX()/spi_wrX()
non-reentrant, but that's OK because calls to them are guaranteed to
be serialized by the per-HCD SPI-thread.
