[PATCH v9 0/4] Add support for Orange Pi 5 Pro

[Dennis Gilmore <dennis@ausil.us>]

This series adds initial support for the Xunlong Orange Pi 5 Pro, based on
the Rockchip RK3588S SoC. The board features eMMC, SD card, NVMe (PCIe),
a Motorcomm YT6801 NIC (PCIe), WiFi/BT (BCM43456), HDMI connected to SoC
(Second port is disabled in this patch), and a 40-pin expansion header.

The series was tested against Linux 7.0

Please take a look.

Thank you,

Dennis Gilmore

Changes in v9:
- removed support for the dp-to-HDMI bridge, will send in a second patch
  set to enable discusion to finish on how to handle its two operating
  modes
- link to v8: https://lore.kernel.org/linux-devicetree/20260425031011.2529364-1-dennis@ausil.us/

Changes in v8:
- Bridge node: renamed label from lt8711uxd to hdmi-bridge
- Bridge node: added vdd-supply = <&vcc3v3_dp>. The vcc3v3_dp regulator
  gates power to the LT8711UXD. regulator-always-on is kept because
  drm_simple_bridge only enables vdd-supply with HPD which does not
  happen without power on
- GPIO output pinctrl groups (bt_wake_gpio, dp_bridge_en, ethernet_en,
  vcc5v0_otg_en, wifi_enable_h) changed from pcfg_pull_none to
  pcfg_pull_down to match the RK3588S power-on-reset default state
- pcie2x1l1 (NVMe): switched from GPIO-mode reset to hardware sideband pins
  using pinctrl-0 = <&pcie30x1m1_1_perstn>, <&pcie30x1m1_1_clkreqn>,
  <&pcie30x1m1_1_waken>. Note: despite the "pcie30" prefix in the DTSI
  group names, the SoC pin-mux table confirms these alt-function 4 pads
  physically route to pcie2x1l1's native PERST#/CLKREQ#/WAKE# inputs.
  reset-gpios is retained alongside the pinctrl entry for U-Boot
  compatibility (pcie_dw_rockchip in U-Boot requires reset-gpios).
- pcie2x1l2 (NIC): added &pcie20x1m0_clkreqn and &pcie20x1m0_waken to
  pinctrl-0
- Renamed pinctrl group vcc3v3_phy1_en to ethernet_en to match the
  schematic signal name (Ethernet_EN)
- link to v7: https://lore.kernel.org/linux-devicetree/20260414214104.1363987-1-dennis@ausil.us/

Changes in v7:
- Fix up whitespace issues identified by checkpatch.pl --strict in
  rk3588s-orangepi-5-5b.dtsi
- checkpatch gave a warning for WARNING: phy-mode "rgmii-rxid" without
  comment, as this was moved over I left it untouched
- Added lontium,lt8711uxd to the compatible enum in the simple-bridge
  binding
- Added lontium,lt8711uxd match entry with DRM_MODE_CONNECTOR_HDMIA to
  the simple-bridge driver
- New patch to rename the regulator labels for the es8388 supplies to
  match the schematics and they all use vcca_*
- Fixed ES8388 PVDD-supply — vcca_3v3_s0 → vcca_1v8_s0, 5 Pro is
  different to 5 and 5b.
- analog-sound: use CPU-as-clock-master on the Pro. The ES8388 is wired to
  i2s2_2ch (the only I2S block physically routed to the codec pins on this
  board), which uses the legacy rockchip_i2s driver. That driver's
  slave-mode trigger path hangs for 200 µs polling I2S_CLR and bails with
  -ETIMEDOUT ("lrclk update failed"). The TDM-capable i2s0/i2s1/i2s5
  blocks served by rockchip_i2s_tdm don't have this issue, which is why
  other mainline ES8388 boards get away with bitclock-master = masterdai.
  Drop bitclock-master/frame-master and the masterdai label to let the I2S
  block generate BCLK/LRCK itself
- Removed regulator-always-on/regulator-boot-on from vcc3v3_dp
- Added pinctrl entries for all GPIO pins (dp_bridge_en, vcc3v3_phy1_en,
  wifi_enable_h, pcie2x1l1_rst, pcie2x1l2_rst)
- DP bridge rework — replaced dp-connector node with proper chain:
    - lt8711uxd bridge node (compatible lontium,lt8711uxd, with port@0/port@1
      endpoints). Bridge power is gated by the vcc3v3_dp regulator, whose
      enable GPIO (GPIO3_PC2) is driven via the dp_bridge_en pinctrl group;
      no enable-gpios/vdd-supply on the bridge node itself.
    - hdmi1-con connector node (compatible hdmi-connector, type a)
    - dp0_out endpoint now points to bridge input instead of old connector
- remove accidentally included unnecessary changes
- link to v6: https://lore.kernel.org/linux-devicetree/20260411024743.195385-1-dennis@ausil.us/

Changes in v6:
- Move the shared configs for the Orange Pi 5 and Orange Pi 5b from each
  devices dts to a shared rk3588s-orangepi-5-5b.dtsi to avoid duplication
- Remove empty ports subnodeis from typea_con
- Move i2s2m1_mclk pinctrl from &i2s2 to the es8388 codec node
- Add dp-con, dp0_out, dp0_in, and vp1 nodes, plus the vcc3v3_dp regulator
  in order to get the second HDMI port working via its transparent
  LT8711UXD DP to HDMI bridge
- link to v5: https://lore.kernel.org/linux-devicetree/20260401010707.2584962-1-dennis@ausil.us/

Changes in v5:
- define a connector node for Type-A port, and list the regulator as its VBUS supply explicitly.
- Requires https://lore.kernel.org/all/20260217-typea-vbus-v1-1-657b4e55a4c2@flipper.net/
- link to v4: https://lore.kernel.org/linux-devicetree/20260310031002.3921234-1-dennis@ausil.us/

Changes in v4:
- rename vcc3v3_pcie20 copied from rk3588s-orangepi-5.dts to vcc3v3_phy1 to match the schematic
- use vcc_3v3_s3 as the supply not vcc5v0_sys for PCIe
- remove the definition for vcc3v3_pcie_m2 as it does not really exist
  as a regulator
- link to v3: https://lore.kernel.org/linux-devicetree/20260306024634.239614-1-dennis@ausil.us/

Changes in v3:
- moved leds from gpio-leds to pwm-leds
- remove disable-wp from sdio
- rename vcc3v3_pcie_eth regulator to vcc3v3_pcie_m2 to reflect the
  purpose
- actually clean up the delete lines and comments missed in v2
- link to v2: https://lore.kernel.org/linux-devicetree/20260304025521.210377-1-dennis@ausil.us/

Changes in v2:
- moved items not shared by orangepi 5/5b/5 Pro from dtsi to 5 and 5b
  dts files
- removed all the comments and deleted properties from 5 Pro dts
- link to v1: https://lore.kernel.org/linux-devicetree/20260228205418.2944620-1-dennis@ausil.us/
