#1341190 — [PATCH 0/5] support gpmi on i.MX6UL/7D and HW bitflip on i.MX6QP/7D

add support for gpmi nand on i.MX6UL and i.MX7D, document the related
properties in DT and add the HW bitflip detection and correction for
i.MX6QP and i.MX7D.

The two document related patch are new and other three patches have no code
change.

Han Xu (5):
  mtd: nand: gpmi: add GPMI NAND support for i.MX7D
  mtd: nand: gpmi: document the clocks and clock-names in DT property
  mtd: nand: gpmi: correct bitflip for erased NAND page
  mtd: nand: gpmi: support NAND on i.MX6UL
  mtd: nand: gpmi: document the new supported chip in DT
