[PATCH 0/2] spi: cadence-quadspi: Fix random issues with Xilinx Versal DMA read

[Sai Krishna Potthuri]

Update Xilinx Versal external DMA read logic to fix random issues
- Instead of having the fixed timeout, update the read timeout based on
the length of the transfer to avoid timeout for larger data size.
- While switching between external DMA read and indirect read, disable the
SPI before configuration and enable it after configuration as recommended
by Octal-SPI Flash Controller specification.

  spi: cadence-quadspi: Update the read timeout based on the length
  spi: cadence-quadspi: Disable the SPI before reconfiguring
