    Subject[PATCH 5.7 137/244] mtd: rawnand: timings: Fix default tR_max and tCCS_min timings
    Date
    From: Miquel Raynal <miquel.raynal@bootlin.com>

    commit 4d8ec041d9c454029f6cd90622f6d81eb61e781c upstream.

    tR and tCCS are currently wrongly expressed in femtoseconds, while we
    expect these values to be expressed in picoseconds. Set right
    hardcoded values.

    Fixes: 6a943386ee36 mtd: rawnand: add default values for dynamic timings
