[PATCH v2 0/3] mtd: rawnand: denali: add new clocks and improve setup_data_interface
From: Masahiro Yamada
Date: Thu Jun 14 2018 - 01:13:18 EST
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
