[PATCH v2 0/3] arm64: dts: rockchip: Add support for Axelera Embedded 111c

[Patrick Barsanti <patrick.barsanti@amarulasolutions.com>]

The Axelera Embedded 111c is an SBC based on the Rockchip RK3588
SoC. It offers efficient AI compute for multi-stream computer vision and
generative AI applications in a compact design.

Product page [1].

This series aims to introduce basic support for the board,
which includes the console, the eMMC, the two Gigabit Ethernet ports,
the four USB ports and the HDMI connector.

Changes in v2:
- The board was renamed by Axelera between v1 and v2, from "Metis
  Compute Board" to "Embedded 111c". Address the name change. Drop
  Conor's Acked-by on the bindings, since the compatible changed. Keep
  it on the vendor-prefix.
- Address Heiko's comment about regulator node names starting with
  "regulator-".
- Address Heiko's comment about non-existent "mem-supply" binding.
- Address Heiko's comment about dropping the unneeded "Use rgmii-rxid
  mode to disable rx delay inside Soc" comment; checkpatch complains
  about uncommented rgmii-rxid, so take the one from
  rk3588-youyeetoo-yy3588.
- Address Heiko's comment about reset lines of the phy nodes being
  incorrectly described in the gmac node; note that these are still not
  described in the phy node because GPIO3_B7 defaults to pull-down,
  which causes the rgmii_phy1 node to never come up; rgmii_phy0's
  reset GPIO, GPIO4_B3, defaults to pull-up, so that node does not
  encounter the same issue. Moving the reset to the parent mdio node
  instead did the trick.
- Address Sashiko's high severity comment about hdmi0 node mixing M0 and
  M1 pinmux groups; use the existing hdmim1_tx0_hpd pinctrl group
  instead of redefining it. HPD is wired to M1 while CEC and DDC use the
  M0 pins. Verified hot-plug detection on external display.
- Address Sashiko's medium comment about "full-pwr-cycle-in-suspend" and
  missing "vmmc-supply" and "vqmmc-supply" on the eMMC node; drop the
  former, add the latter two.
- Address Sashiko's medium comment about the pmic node lacking a pinctrl
  assignment for the interrupt pin; add it.
- Address Sashiko's medium comment about the "vcc3v3_hubreset" regulator
  hack; describe the two GL3523 hubs linked with peer-hub.
- Address Sashiko's low comment about defined-but-never-referenced
  regulators without regulator-always-on property; drop them, alongside
  their pinctrls.
- Mux PCIEX4_PERST_N as GPIO, to match it being used via reset-gpios.
- Drop the unused input.h include.
- Drop the unused rtc label.
- Drop the local PCIe x1 pinctrl groups, which duplicated the
  pcie30x1m1_1_* groups in rk3588-base-pinctrl.dtsi.
