[PATCH 1/6] dt-bindings: mtd: qcom,nandc: Document the SDX75 NAND
From: Kaushal Kumar
Date: Thu Mar 13 2025 - 09:12:57 EST
Document the QPIC NAND controller v2.1.1 being used in
SDX75 SoC and it uses BAM DMA.
SDX75 NAND controller has DMA-coherent and iommu support
so define them in the properties section, without which
'dtbs_check' reports the following error:
nand-controller@1cc8000: Unevaluated properties are not
allowed ('dma-coherent', 'iommus' were unexpected)
