Subject: [PATCH v2] ARM: arch: dts: qspi: Add QSPI config to the NXP IMX8MN-EVK board
Date: Tue, 1 Mar 2022 14:23:08 +0100 [thread overview]
Message-ID: <20220301132308.343496-1-joacim.zetterling@westermo.com> (raw)
Add QSPI support in the default config and DTS files for the
NXP IMX8MN-EVK board. To be able to use it You also need the
QSPI driver enabled.
Tested on the NXP IMX8MN-EVK board as well as on an IMX8MN
custom bord supporting a QSPI flash. Tested with the memory
dump command i.e. 'md -s /dev/m25p0'.

Changes v2:
- Removed the "default" pinctrl names from iomuxc
- Renamed the flexspi device name
