From b866b9278a3b87e7f70f026785c002b109258022 Mon Sep 17 00:00:00 2001 From: Ye Li Date: Wed, 14 Aug 2019 11:31:31 +0000 Subject: [PATCH] spi: fsl_qspi: Update write data size for page program LUT The write data size can be overwritten by writing to the IDATSZ field of IPCR register. Since the driver always updates the IDATSZ in page program operation. Set the LUT data size to 0 to align the codes with iMX.
