Subject: [PATCH 2/3] spi: spi-nxp-fspi: Add driver support for imx8dxl
Date: Mon, 1 Mar 2021 16:02:29 +0530 [thread overview]
Message-ID: <20210301103230.1816168-3-kuldeep.singh@nxp.com> (raw)
In-Reply-To: <20210301103230.1816168-1-kuldeep.singh@nxp.com>
From: Han Xu <han.xu@nxp.com>
Add driver support for imx8dxl which support read through IP bus only
and disable AHB bus due to an IC errata. Use the pre-defined quirk
FSPI_QUIRK_USE_IP_ONLY directly in device-type data to disable AHB read.
