      The i.MX8M Nano has several SAI nodes available to it.
      Enable them.

      arm64: dts: imx8mn: Enable Asynchronous Sample Rate Converter · 970406ea
      Adam Ford authored
      The driver exists for the Enhanced Asynchronous Sample Rate Converter
      (EASRC) Controller, but there isn't a device tree entry for it.
      
      On the vendor kernel, they put this on a spba-bus for SDMA support.
      
      Add the node for the spba-bus with the easrc node inside.

      arm64: dts: ls1028a: make the eMMC and SD card controllers use fixed indices · 2e6cde96
      Vladimir Oltean authored
      As the boot order in the kernel continues to change, sometimes it may
      happen that the eSDHC controller mmc@2150000 (the one for eMMC) gets
      probed before the one at mmc@2140000 (for external SD cards). The effect
      is that the eMMC controller gets the /dev/mmcblk0 name, and the SD card
      gets /dev/mmcblk1.
      
      Since the introduction of this SoC, that has never happened in practice,
      even though it was never guaranteed in theory. Setting
      "root=/dev/mmcblk0p2" in /proc/cmdline has always caused the kernel to
      use the second partition from the SD card as the rootfs.
      
      The NXP development boards are typically shipped with either
      - LSDK, which uses "root=UUID=", or
      - OpenIL, which uses "root=/dev/mmcblkNp2"
      
      So for OpenIL, let's preserve that old behavior by adding some aliases
      which create naming consistency (for LSDK it doesn't matter):
      - the SD card controller uses /dev/mmcblk0
      - the eMMC controller uses /dev/mmcblk1
      
      For the Kontron SL28 boards, Michael Walle says that they are shipped
      with "root=UUID=" already, so the probing order doesn't matter, but it
      is more natural to him for /dev/mmcblk0 to be the eMMC, so let's do it
      the other way around there.
      
      The aliases are parsed by mmc_alloc_host() in drivers/mmc/core/host.c.
