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 v3: - Change the patch order so that the bug-fix one comes the first
Changes in v2: - Split patches into sensible chunks - Split patches into sensible chunks
Masahiro Yamada (3): mtd: rawnand: denali_dt: add more clocks based on IP datasheet mtd: rawnand: denali_dt: use dev as a shorthand of &pdev->dev mtd: rawnand: denali: optimize timing parameters for data interface
