Subject: [PATCH v4 0/2] TQ-Systems TQMa62xx SoM and MBa62xx board

This adds Device Trees for our AM62x-based SoM TQMa62xx and its
reference carrier board MBa62xx.

Not yet included are overlays to enable LVDS display output and MIPI-CSI
camera input.

Changes in v4:
- Rebase onto latest ti-k3-dts-next
- Reorder boot phase tags after other standard DT properties
- Add missing supply regulators in SPI-NOR flash and USB hub
- Set status = "okay" in &cpsw3g, as it is disabled in k3-am62-main.dtsi
  now
- Add disabled 1400MHz OPP entry (will be enabled by bootloader if
  supported by PMIC configuration)
- Update copyright years in new files

Changes in v3:
- Rebased onto ti-k3-dt-for-v6.18
- 3 of the 5 patches in v2 have been applied already and are dropped
- Include k3-am62-ti-ipc-firmware.dtsi, drop now redundant configuration
- Change node name for MCU reserved memory to 'memory'
- Use rgmii-id PHY mode
- Drop now redundant ti,rx-internal-delay
- Update simple-audio-card,name to match other TQ SOMs with compatible
  configuration
- Reference dss_pins in dss node (actual display support will be added
  in a follow-up patch series)
- Consistently use GPIO_ACTIVE_HIGH define
- Drop unneeded usb0 quirk flags
- Add boot phase tags

Changes in v2:
- Collected acks and reviews
- Rebased onto v6.13-rc1
