Fix ethernet PHY not being detected on the NanoPi Zero2. The MDIO bus
scan was failing because the PHY reset GPIO was only defined on the
PHY child node inside the MDIO bus. The kernel processes this reset
after the MDIO scan, but the PHY needs reset released before it will
respond on the bus.
Move the reset control to the gmac1 node using snps,reset-gpios and
snps,reset-delays-us properties. The stmmac driver handles these
during MDIO bus registration, before scanning for PHY devices.
Also change CONFIG_MOTORCOMM_PHY from module (m) to built-in (y) in
the rockchip64 kernel config. As a module, the PHY driver loads too
late for the MDIO bus scan to find the PHY during boot.
Tested on hardware: ethernet link at 1000Mbps full duplex confirmed.

Enable USB OTG/gadget mode on the NanoPi Zero2 USB-C port by adding
extcon binding and snps,dis_u2_susphy_quirk to the DWC3 node. The
extcon binding coordinates role switching between the DWC3 and USB2
PHY OTG state machines, which previously conflicted and caused memory
corruption.
Also fix a use-after-free in the inno-usb2 PHY driver where the OTG
state machine delayed works (otg_sm_work, chg_work, sm_work) were not
canceled on driver removal. This caused a kernel panic ~2 seconds
after boot when dr_mode was set to "otg" or "peripheral". The fix
registers devm cleanup actions to cancel the works automatically.
Tested on hardware: USB-A host port, USB-C gadget (NCM ethernet),
and USB-C OTG mode all verified working.

This commit introduces a patch for the rockchip64 kernel (current 6.18 and
edge 7.0 branches) to fix audio routing issues affecting the ES8328 codec.
The patch modifies the ASoC es8328 driver to explicitly allow sharing the
LRCK (Left/Right Clock) between the microphone and playback interfaces.
This is required for hardware designs where capture and playback must share
the same clock line.

- Configured USB3 Type-A ports (with USB2 OTG PHY) and explicitly set the
USB-C port to power-delivery only (no FUSB302/data/alt-mode).
- Configured combphy2_psu for NVMe M.2 slot support by disabling
conflicting USB3 modes.
- Re-mapped fan to PWM2 and LEDs to PWM3/PWM15.
- Added full AP6256 Wi-Fi/Bluetooth support (SDIO and UART9).

- Resolved specific stmmac/motorcomm driver compilation errors and
panics on kernel 6.18.
3. Board Configuration (orangepi5pro.csc):
- Refactored U-Boot configuration selection logic, segregating mainline
and vendor branches correctly.

This commit adds a suite of 4 patches for U-Boot v2025.10 to enable
full support for the Xunlong Orange Pi 5 Pro SBC.
The Orange Pi 5 Pro introduces several significant hardware departures
from the base Orange Pi 5, necessitating specific driver and DTS
adjustments:
1. Networking (Motorcomm YT6801):
- The Pro variant replaces the SoC's built-in GMAC1 NIC with a
PCIe-attached Motorcomm YT6801 controller.
- Introduce a new glue driver (dwc_eth_qos_motorcomm) to bridge
the core DWC EQoS IP to the PCIe bus.
- Core EQoS driver is modified to support the YT6801's unique
32-byte descriptor size and Descriptor Skip Length requirements.
- Auto-generation of MAC addresses from CPU ID is disabled to
preserve the hardware's native eFuse MAC.
2. Audio and I/O:
- Audio routing is moved from I2S1 to I2S2 (M1 mux) with the
ES8388 codec on I2C3.
- LEDs are remapped from GPIO to PWM control (PWM3/PWM15).
- Headphone amplifier enable is remapped to GPIO4_PB5.
3. Thermal and Power:
- PWM Fan control is implemented with a specific 20ms (50Hz)
period. This is CRITICAL because the hardware's RC filter gate
logic causes MOSFET overheating if standard 25kHz PWM is used.
4. Wireless:
- Full support for the AP6256 module via SDIO and UART9.
Patch Summary:
- [0001] Board support (DTS, defconfig, doc). DTS based on initial
submission by Dennis Gilmore.
- [0002] Motorcomm YT6801 PCIe glue driver and PHY support.
- [0003] Core EQoS driver extension for descriptor/DSL overrides.
- [0004] Rockchip board MAC setup bypass for Pro hardware.

Remove patch 1003 which incorrectly changes exit() to pass struct device *
instead of struct platform_device *. In kernel 6.12, the signature is:
void (*exit)(struct platform_device *pdev, void *priv);
Remove incompatible patches that try to use non-existent kernel APIs:
- 1001: stmmac_axi_blen_to_mask() and axi_blen_regval don't exist in 6.12
- 1002: plat->core_type and DWMAC_CORE_GMAC don't exist in 6.12
The base patch (1000) already uses the correct 6.12 APIs:
- axi->axi_blen array
- plat->has_gmac field
- Fix the issue that downstream MSM sdhc driver cannot work on 6.18.14
or newer kernel
- Switch back to downstream MSM sdhc driver for Ayn Odin2 devices to
fix the IO performance regression brought by upstream driver.
Before this fix, average sequential read bandwidth on a UHS-I SDR104
card is 16.8MiB/s. After this fix applied, it is 85.1MiB/s.
It fixes commit f785a6d9fdd2f6751f739d6863e1beec6d98484b

* rockchip64: add USB support for RK3528 / NanoPi Zero2 (6.18 + 7.0)
Add three kernel patches for USB support on the RK3528 SoC:
- phy-rockchip-inno-usb2: Add RK3528 USB2 PHY driver support
- rk3528.dtsi: Add xHCI, EHCI, OHCI and USB2 PHY device tree nodes
- nanopi-zero2: Enable USB host and OTG ports
Tested on hardware: USB storage, PCIe (AX210 WiFi) all working.
* rockchip64: fix USB patches for RK3528 (6.18 + 7.0)
- Fix error handling in USB2 PHY tuning: use individual return checks
instead of ret |= pattern (thanks @coderabbitai)
- Remove power-domains properties from USB DTS nodes: causes kernel
panic (synchronous external abort in rockchip_pmu_set_idle_request)
as RK3528 PMU idle request registers are not ready for these domains
- Fix patch hunk headers to match updated line counts
Tested on hardware: both current (6.18) and edge (6.19) boot
successfully with working USB.
* rockchip64: rk3528: change USB-C dr_mode from host to otg (6.18 + 7.0)
The DWC3 controller on the NanoPi Zero2 USB-C port was set to
host-only mode, preventing USB gadget functionality. Change to
OTG mode to support both host and peripheral use cases.
* rockchip64: rk3528: fix USB PHY regmap and revert dr_mode to host (6.18 + 7.0)
Fix the USB2 PHY driver probe to use phy_base for port register access
instead of the vo_grf syscon. The RK3528 PHY port registers (UTMI
status, VBUS detection, etc.) reside in the PHY register space, not
in the Video Output GRF. Using the wrong regmap caused register
accesses to hit unrelated hardware when the OTG state machine runs.
Revert dr_mode back to "host" as OTG/peripheral mode triggers a kernel
panic from timer corruption during DWC3 gadget initialization. This
needs further investigation before OTG support can be enabled.
* change regulator-min-microvolt to 1.4V
* adapt new voltage regulator values
* revert vdd_arm regulator due to boot time errors
* revert vdd_arm min voltage due to errors
* Generic aic8800-dkms.sh extension
* fix typo in filename
* remove file
Voltages for "gpu_opp_table" and "vdd_arm" were wrongly using default
values instead of the customized values from the vendor image, leading
to dmesg errors like
[ 19.709834] core: _opp_supported_by_regulators: OPP minuV: 1075000 maxuV: 1075000, not supported by regulator
[ 19.710075] lima ff300000.gpu: _opp_add: OPP not supported by regulators (200000000) 0xBEBC200
Thanks to Shadowrom2020 for noticing.
Update the I2S MCLK output gate clock patches to match the upstream v3
series. Changes from previous version:
- Split into 4 patches (was 3): added separate patch for
RK3588_SYSGRF_SOC_CON6 define in rk3588_grf.h
- Use named constant RK3588_SYSGRF_SOC_CON6 instead of magic 0x0318
- Add u-boot patch for clock ID bindings (needed by board DTS files)
6.18 uses kzalloc(sizeof(...)) as kzalloc_obj is not available.
7.0 uses kzalloc_obj as recommended by upstream reviewer.
