[PATCH v4 00/10] Add peripheral support for imx8mm-nitrogen-r2 board

[Adrien Grassein]

Hi,

this patch set is to add several peripheral support for the
imx8mm-nitrogen-r2 board.

Thanks,

Update in v2:
  - Fix some typo found in v1;
  - Fix UART description

Update in v3
  - Fix wlan vqmcc regulator;
  - Remove useless clock node;
  - Split UART patch

Update in v4
  - Fix audio binding;
  - Add a patch to fix eMMC binding.

Thanks,

Adrien Grassein (10):
