[PATCH 0/4] arm64: dts: rockchip: add Forlinx OK3568-C

[Dmitry Yashin]

This series add support for Forlinx OK3568-C board based on FET3568-C SoM
(rk3568). Patches 1-3 add .dtsi for FET3568-C and .dts for OK3568-C.
Patch 4 adds .dtso for FIT-PCIE-SATA adapter that allows to connect
SATA drives to the board.

Note: tested on v1.1 board. On v1.2 RTL8211F phys use dedicated
crystal oscillator instead of 25 MHz reference clock from SoC. Patch
should be compatible with both revisions, as in [1] solution.

[PATCH 1/4] dt-bindings: arm: rockchip: add Forlinx FET3568-C

[Dmitry Yashin]

FET3568-C is an System on Module made by Forlinx based on Rockchip RK3568.
This SoM used by OK3568-C Board.

FET3568-C features:
- Rockchip RK3568
- DDR4 1/2/4/8 GB
- eMMC 8/16/32/64 GB
- RK809 PMIC

Add devicetree binding for Forlinx FET3568-C SoM.

arm64: dts: rockchip: add Forlinx FET3568-C

This commit adds the device tree source for the Forlinx FET3568-C System on
Module based on the Rockchip RK3568 SoC. It configures the CPU, GPU, I2C,
PMIC, eMMC, and basic LED nodes for the SoM.

[Severity: Low]
This file uses LED_COLOR_ID_BLUE and LED_FUNCTION_HEARTBEAT but doesn't
include <dt-bindings/leds/common.h>. Could we include the header directly
in this .dtsi file so it is fully self-contained? Relying on parent .dts
files to include it can cause build failures if this file is included by
other boards.

Author: Dmitry Yashin <dmt.yashin@gmail.com>

arm64: dts: rockchip: add Forlinx OK3568-C

This commit adds support for the Forlinx OK3568-C board, which is the
carrier board for the FET3568-C System on Module. It maps the peripherals
and components for the board including connectivity modules like 5G, WiFi,
and Bluetooth.

[Severity: Medium]
The modem_5g_reset pinctrl node is defined here but does not appear to be
referenced in any pinctrl-0 property or assigned to a device node,
regulator, or gpio-hog.

Without being actively driven, could this prevent the 5G modem from
initializing and enumerating properly if it requires this reset signal?

[Severity: Medium]
Similar to the modem reset, the wifi_host_wake pinctrl group configures
a GPIO for handling out-of-band host wake interrupts from the WiFi
module, but it is completely isolated. It isn't referenced by the
sdmmc2 node's pinctrl-0, and the corresponding interrupts property is
missing.

Does this missing configuration break Wake-on-WLAN and sleep power
management for the WiFi module during system suspend?

[Severity: Medium]
While pinctrl-0 sets up the hardware pins as GPIOs, the corresponding DT
properties (device-wakeup-gpios, interrupts, reset-gpios) required by
the nxp,88w8987-bt binding are missing from this node.

Without device-wakeup-gpios and the wakeup interrupt, will the
btnxpuart driver be unable to perform power management signaling and
break sleep/wake functionality? Also, without a driver managing the
bt_reg_on GPIO, could the chip remain in reset and fail to initialize?

Yet another rockchip board which gets RGMII delays wrong.
