   4 Subject: [PATCH] dtoverlays: Remove i2c0mux and i20if status from
   5  edt-ft5406.dtsi
   6
   7 edt-ft5406.dtsi is included from vc4-kms-dsi-7inch which was
   8 also setting i2c0mux and i2c0if status fields. This meant that
   9 dtoverlay wouldn't apply the overlay due to multiple fragments
  10 changing the same parameter.
  11
  12 Move the enable from edt-ft5406.dtsi to edt-ft5406-overlay.dts
  13 for when it should be needed as an independent overlay.
