Subject: [PATCH 2/4] spi: spi-nxp-fspi: change the default lut index
Date: Fri, 20 Aug 2021 15:44:01 +0800	[thread overview]
Message-ID: <1629445443-10300-2-git-send-email-haibo.chen@nxp.com> (raw)
In-Reply-To: <1629445443-10300-1-git-send-email-haibo.chen@nxp.com>

From: Haibo Chen <haibo.chen@nxp.com>

The fspi dynamic lut use the last lut for all IPS operations, the
imx8ulp only supports 15 luts, so change the last lut index from
31 to 15.
