On iMX7D SabreSD board, the QSPI has pins conflict with EPDC (default). To use QSPI, users have to rework the board (de-populate R388-R391, R396-R399 populate R392-R395, R299, R300). So we add new DTS file and new defconfig dedicated for QSPI.
Other changes to support the DM QSPI: - Add QSPI node and alias spi0. - Modify spi4 (spi-gpio) node and add alias spi5 for it to avoid req conflict - Add EPDC node in imx7d.dtsi and disable it in imx7d-sdb-qspi.dts to align with kernel and also present the conflict. - Add -u-boot.dtsi to modify compatible string of mx25l51245g@0 to "spi-flash" - Remove iomux settings of qspi in board codes which is not needed for DM driver.
Signed-off-by: Ye Li ye.li@nxp.com --- Changes in v2: - Add imx7d-sdb-qspi-u-boot.dtsi for u-boot "spi-flash" compatible string
