Subject: [Patch v2 3/4] spi: spi-nxp-fspi: Add imx8dxl driver support
Date: Tue, 2 Mar 2021 18:19:35 +0530 [thread overview]
Message-ID: <20210302124936.1972546-4-kuldeep.singh@nxp.com> (raw)
In-Reply-To: <20210302124936.1972546-1-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.
