The ->setup_data_interface() hook needs to know the clock frequency.
In fact, this IP needs three clocks, bus "which clock?" is really
confusing.  (It is not described in the DT-binding at all.)

This series adds more clocks.  In the new binding, three clocks
are required: core clock, bus interface clock, ECC engine clock.

This series also takes care of the backward compatibility by
providing hardcoded values in case the new clocks are missing.
So, existing DT should work.


Changes in v2:
  - Split patches into sensible chunks

Masahiro Yamada (3):
  mtd: rawnand: denali_dt: use dev as a shorthand of &pdev->dev
  mtd: rawnand: denali_dt: add more clocks based on IP datasheet
  mtd: rawnand: denali: optimize timing parameters for data interface
