[PATCH v5 0/3] TQMLS1021A support

[PATCH v5 0/3] TQMLS1021A support

[Alexander Stein]

Hi,

thanks everyone for the feedback. This is the fifth round of this series to
add support for the TQMLS1021A using the MBLS1021A mainboard.
Removing the 'dma-coherent' property was a workaround carried on from older
downstream kernels and is not necessary anymore.
The same goes for adjusting the size for 'scfg' node. Removing this also
fixes the node label ordering.

Changes in v5:
* Add newline for include header grouping
* Put status property at the end of properties (lpuart0)
* Do not remove 'dma-coherent' for sata
* Do not adjust 'reg' property for 'scfg'

Changes in v4:
* Dropped display overlay for now as DCU patch is still pending
* Rebase to next-20230721
* Move status property to last position
* Rename stmpe811 node name
* Remove superfluous #address-cells and #size-cells for stmpe811
* Add missing interrupt-controller properties for stmpe811
* Remove superfluous ESDHCI compatible overwrite in SoM .dtsi

Best regards,
Alexander

[PATCH v5 3/3] ARM: dts: ls1021a: add TQMLS1021A flash partition layout

[Alexander Stein]

The bootloader does not add the partitions into DT, so add them manually
here.
