Patch 1/2
  The new state node qup_uart7_sleep is causing a dt-check warning because the 
  base DTSI (sc7280.dtsi) is defined with individual pin configurations

----

Missing space before 'interrupts'.

Align by the opening angle bracket.

Align '<' vertically.

Vertical list, please, aligned by the opening quote.

Also please add empty line before status.
