[PATCH v2 0/5] arm64: dts: rockchip: add Forlinx OK3568-C

[Dmitry Yashin]

This series add support for Forlinx OK3568-C board based on FET3568-C
SoM (rk3568).

Patch 1 adds missing reset-gpios property to rfkill-gpio binding.
Patches 2-4 add .dtsi for FET3568-C and .dts for OK3568-C (depends on
 patch 1 to suppress dt warnings).
Patch 5 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.

Changes in v2:
- added patch for rfkill-gpio's dt-binding with reset-gpios property to
  suppress dt warnings
- removed mmc-pwrseq. AW-CM358SM has only power management PDn pin
  for both wifi and bt. Using shared wifi_bt_reg_on regulator fixes
  bluetooth failure on cold boots
- added bluetooth wakein/wakeout pins
- moved leds/common.h to the SoM dtsi
- switched gmac's phy-mode to rgmii-id
- added rfkill-gpio for modem reset
- dropped unused wifi and bt pinctrl's
- Link to v1: https://patch.msgid.link/20260930-ok3568-c-v1-0-a0ffd55f5c95@gmail.com

[PATCH v2 1/5] dt-bindings: net: rfkill-gpio: document reset-gpios property

[Dmitry Yashin]

rfkill-gpio driver requiers at-least one of the gpios to be defined:
shutdown-gpios or reset-gpios. Document missing reset-gpios property.
Also add example for wwan with both gpios.

[PATCH v2 5/5] arm64: dts: rockchip: add FIT-PCIE-SATA overlay

[Dmitry Yashin]

FIT-PCIE-SATA V1.0 is an adapter that included with OK3568-C board
and allows to connect SATA drives to the device.

Add overlay to use combphy2 in SATA mode.
