[PATCH 0/3] arm64: tegra: Add iommu and dma properties for Tegra194 QSPI

From: Aaron Kling via B4 Relay

The reason for this is to properly support the spi nor chip on the
Jetson Xavier NX module. Prior to this, it would time out on all
transfers and sometimes even trigger a cbb fault, locking up the entire
unit. With this, reading and writing to the flash memory works as
expected.
