Please don't send new versions so quickly. We all work
different timezones and are busy. Krzysztof reviewed v1.

Add the ArmSoM CM5, an RK3576 compute module (rk3576-armsom-cm5.dtsi),
and its CM5-IO carrier (rk3576-armsom-cm5-io.dts). The module has the
RK806 PMIC, HYM8563 RTC, eMMC, GMAC0 with an on-module MotorComm YT8531
PHY, and the SDIO bus for the on-module WiFi. The carrier adds HDMI, a
GbE RJ45, two USB-A ports behind a USB3 hub, USB-C with FUSB302 and DP
alt-mode, a PCIe 2.0 x1 M.2 slot, microSD, status LEDs and a 40-pin
header.
The YT8531 has no crystal, so it uses the SoC 25 MHz reference output,
described on the gmac node as clk_mac_refout. Its reset is described at
the MDIO bus level: mdiobus releases a bus level reset before it scans
for PHY IDs, whereas a per-PHY reset-gpios is only applied once the PHY
has been found, which never happens while the PHY is still in reset.

Add the ArmSoM CM5, an RK3576 compute module (rk3576-armsom-cm5.dtsi),
and its CM5-IO carrier (rk3576-armsom-cm5-io.dts). The module has the
RK806 PMIC, HYM8563 RTC, eMMC, GMAC0 with an on-module MotorComm YT8531
PHY, and the SDIO bus for the on-module WiFi. The carrier adds HDMI, a
GbE RJ45, two USB-A ports behind a USB3 hub, USB-C with FUSB302 and DP
alt-mode, a PCIe 2.0 x1 M.2 slot, microSD, status LEDs and a 40-pin
header.
The YT8531 has no crystal, so it uses the SoC 25 MHz reference output,
described on the gmac node as clk_mac_refout. Its reset is described at
the MDIO bus level: mdiobus releases a bus level reset before it scans
for PHY IDs, whereas a per-PHY reset-gpios is only applied once the PHY
has been found, which never happens while the PHY is still in reset.

Thank you for your contribution! Sashiko AI review found 4 potential issue(s) to consider:
- [Medium] Contradictory suspend state configuration for `vdd_cpu_lit_s0` and `vdd_gpu_s0` regulators.
- [Medium] `full-pwr-cycle-in-suspend` specified for eMMC without a `vmmc-supply`.
- [Low] Missing ES8388 audio codec device node on I2C0 bus.
- [Low] Use of deprecated `gpio` property instead of `gpios` in `vcc_3v3_pcie` fixed regulator.

arm64: dts: rockchip: Add ArmSoM CM5 and CM5-IO
Add the ArmSoM CM5, an RK3576 compute module (rk3576-armsom-cm5.dtsi),

RK806 PMIC, HYM8563 RTC, eMMC, GMAC0 with an on-module MotorComm YT8531
PHY, and the SDIO bus for the on-module WiFi.

[Severity: Low]
Does this regulator intentionally use the deprecated gpio property instead
of gpios? Using gpios here would match standard devicetree bindings and
the style used by other regulators in this file.

The comment above mentions the ES8388 audio codec at 0x10, but is the device
node for it missing here in &i2c0?

[Severity: Medium]
Can a regulator be simultaneously turned off and maintain a specific suspend
voltage? Specifying both regulator-off-in-suspend and
regulator-suspend-microvolt appears contradictory and may cause unexpected
behavior during suspend.

[Severity: Medium]
Similar to vdd_cpu_lit_s0, is it correct to include both
regulator-off-in-suspend and regulator-suspend-microvolt here for the GPU
regulator?

[Severity: Medium]
Will full-pwr-cycle-in-suspend have any effect if vmmc-supply is not
specified? Without a vmmc-supply to control the power, the MMC core may not
be able to actually fully power down the device, potentially leading to state
mismatches on resume.

Add the ArmSoM CM5, an RK3576 compute module (rk3576-armsom-cm5.dtsi),
and its CM5-IO carrier (rk3576-armsom-cm5-io.dts). The module has the
RK806 PMIC, HYM8563 RTC, eMMC, GMAC0 with an on-module MotorComm YT8531
PHY, and the SDIO bus for the on-module WiFi. The carrier adds HDMI, a
GbE RJ45, two USB-A ports behind a USB3 hub, USB-C with FUSB302 and DP
alt-mode, a PCIe 2.0 x1 M.2 slot, microSD, status LEDs and a 40-pin
header.
The YT8531 has no crystal, so it uses the SoC 25 MHz reference output,
described on the gmac node as clk_mac_refout. Its reset is described at
the MDIO bus level: mdiobus releases a bus level reset before it scans
for PHY IDs, whereas a per-PHY reset-gpios is only applied once the PHY
has been found, which never happens while the PHY is still in reset.

Author: Jiaxing Hu <gahing@gahingwoo.com>
arm64: dts: rockchip: Add ArmSoM CM5 and CM5-IO
Add the ArmSoM CM5, an RK3576 compute module (rk3576-armsom-cm5.dtsi),
and its CM5-IO carrier (rk3576-armsom-cm5-io.dts). The carrier adds HDMI, a
GbE RJ45, two USB-A ports behind a USB3 hub, USB-C with FUSB302 and DP
alt-mode, a PCIe 2.0 x1 M.2 slot, microSD, status LEDs and a 40-pin
header.

[Severity: Medium]
Is the ES8388 audio codec node missing from this bus? Both the file header
and the comment above indicate it should be on i2c0 at address 0x10, but
only the FUSB302 USB-C PD controller node is present.

Add the ArmSoM CM5, an RK3576 compute module (rk3576-armsom-cm5.dtsi),
and its CM5-IO carrier (rk3576-armsom-cm5-io.dts). The module has the
RK806 PMIC, HYM8563 RTC, eMMC, GMAC0 with an on-module MotorComm YT8531
PHY, and the SDIO bus for the on-module WiFi. The carrier adds HDMI, a
GbE RJ45, two USB-A ports behind a USB3 hub, USB-C with FUSB302 and DP
alt-mode, a PCIe 2.0 x1 M.2 slot, microSD, status LEDs and a 40-pin
header.
The YT8531 has no crystal, so it uses the SoC 25 MHz reference output,
described on the gmac node as clk_mac_refout. Its reset is described at
the MDIO bus level: mdiobus releases a bus level reset before it scans
for PHY IDs, whereas a per-PHY reset-gpios is only applied once the PHY
has been found, which never happens while the PHY is still in reset.

Thank you for your contribution! Sashiko AI review found 3 potential issue(s) to consider:
- [High] The 25 MHz reference clock output (`clk_mac_refout`) for the crystal-less motorcomm YT8531 PHY will remain disabled because the `dwmac-rk` MAC driver ignores it for RGMII interfaces, leading to MDIO timeouts and a non-functional PHY.
- [Low] The ES8388 audio codec is claimed to be supported on I2C0 by the file header and block comments, but its node implementation is entirely missing.
- [Low] Use of deprecated 'gpio' property instead of 'gpios' in regulator-fixed node.

--- Patch [2]: [PATCH v2 2/2] arm64: dts: rockchip: Add ArmSoM CM5 and CM5-IO ---
commit e75134401985ec8dc82c1bb4f3f58610d1d03afd
Author: Jiaxing Hu <gahing@gahingwoo.com>
arm64: dts: rockchip: Add ArmSoM CM5 and CM5-IO
Add the ArmSoM CM5, an RK3576 compute module (rk3576-armsom-cm5.dtsi),
and its CM5-IO carrier (rk3576-armsom-cm5-io.dts).

[Severity: Low]
Does this violate the regulator-fixed device tree binding schema? The schema
expects the gpios property instead of the deprecated gpio property, which may
trigger dtbs_check warnings.

[Severity: Low]
This isn't a bug, but the block comment mentions the ES8388 audio codec at
address 0x10, yet the node isn't implemented here. Could this cause confusion
for anyone attempting to use the audio functionality?

[Severity: High]
Will the 25 MHz reference clock output remain disabled here? The dwmac-rk
driver (in drivers/net/ethernet/stmicro/stmmac/dwmac-rk.c) only parses and
enables clk_mac_refout if the phy-mode is exactly RMII.
Since the mode is configured as rgmii-rxid, the MAC driver will ignore the
clock. Additionally, neither the generic PHY framework nor the motorcomm driver
automatically enable clocks specified in the PHY node before the MDIO bus scan,
which could lead to MDIO timeouts and a non-functional Ethernet interface.
