Does this series depend on any other patches or Octal DTR?
No. This series is for Quad SPI parts and independent from any other patches. The #1, #2, and #3 patches in this series come from Pratyush's series [0] that adds Octal DTR support. However, those three patches introduce generic hooks and do not contain any specific changes for Octal DTR.
