Subject: [PATCH v2 2/9] mtd: rawnand: timings: Fix default tR_max and tCCS_min timings
Date: Fri, 24 Apr 2020 18:40:35 +0200	[thread overview]
Message-ID: <20200424164042.26572-3-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20200424164042.26572-1-miquel.raynal@bootlin.com>

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

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