- Build v7_cpu_resume() unconditionally to fix system hang in case that
    suspend is disabled but cpuidle support is enabled.
  - Drop unexisting Ethernet PHY device from imx8qxp-mek board.
  - Fix SRAM compatible strings on imx6dl-colibri-eval-v3 board.
  - Fix imx-scu driver to make sure that all messages words are written
    sequentially.
  - A series from Leonard Crestez to fix i.MX SC API users, having all
    messages aligned on 4 bytes.
  - Fix eMMC supply for phycore-som board.
  - Drop bogus frequency setting from imx7-colibri SD/MMC device, so that
    HS200 mode starts working and delivers better performance.
  - Fix opp-supported-hw for i.MX7D to get consumer and industrial parts
    work with correct frequency settings.
  - Restore MDIO compatible to the correct one for LS1021A SoC.
