This patch queue addresses the power sequence of the display controller
of the imx8mm SoC. The sequence mentioned in example code 5 in section
5.2.9.5 of reference manual imx-8MMini-yhsc.pdf was not being performed.
This meant that the display controller was not coming up.

Viraj Shah (4):
  soc: imx: gpcv2: Power sequence for DISP
  soc: imx: imx8m-blk-ctrl: Display Power ON sequence
  soc: imx: imx8m-blk-ctrl: Add reset bits for mipi dsi phy
  arm64: dts: imx8mm.dtsi: Add resets for dispmix power domain.
