[PATCH v2 0/2] mtd: nand: wait for tWHR, and fix the setup_data_interface of Denali

Show all headers | View raw

1/2 : add NAND_WAIT_TWHR and nand_whr_delay().
      You can set this new flag if you want nand_command(_lp)
      to insert tWHR delay where needed.

2/2 : Fix Denali setup_data_interface.
      Boris' suggestion in v1 was a good reminder that
      made me realize tCCS was missing in the driver.  Fix it now.


Changes in v2:
  - Add nand_whr_delay() helper
    Wait for tWHR only for drivers that explicitly set NAND_WAIT_TWHR flag
  - newly added

Masahiro Yamada (2):
  mtd: nand: wait for tWHR after NAND_CMD_STATUS / NAND_CMD_READID
  mtd: nand: denali: fix setup_data_interface to meet tCCS delay
