Subject: [PATCH] ARM: arch: dts: qspi: Add QSPI support to the NXP IMX8MN-EVK board
Date: Mon, 28 Feb 2022 18:03:28 +0100	[thread overview]
Message-ID: <20220228170328.248391-1-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'.
