Subject: [PATCH 0/4] spi: atmel-quadspi: Fix AHB memory accesses

Starting with the move of the atmel-quadspi driver under SPI,
the following error could be seen when mounting a 16MByte ubifs:
UBIFS error (ubi0:0 pid 1893): check_lpt_type.constprop.6: invalid type (15) in LPT node type

1/4 fixes AHB accesses. The rest of the patches are small optimizations.
Tested on both sama5d2 and sam9x60.

Tudor Ambarus (4):
  spi: atmel-quadspi: Fix AHB memory accesses
  spi: atmel-quadspi: Drop superfluous set of QSPI_IFR_APBTFRTYP_READ
  spi: atmel-quadspi: Write QSPI_IAR only when needed
  spi: atmel-quadspi: Move common code outside of if else
