Commit 8a1365c7bb ("arm64: dts: lx2160a: add pinmux and i2c gpio to
support bus recovery") introduced pinmux nodes for lx2160 i2c
interfaces, allowing runtime change between i2c and gpio functions
implementing bus recovery.
However, the dynamic configuration area (overwrite MUX) used by the
pinctrl-single driver initially reads as zero and does not reflect the
actual hardware state set by the Reset Configuration Word (RCW) at
power-on.
Because multiple groups of pins are configured from a single 32-bit
register, the first write from the pinctrl driver unintentionally clears
all other bits to zero.
For example, on the LX2162A Clearfog, RCWSR12 is initialized to
0x08000006. When any i2c pinmux is applied, it clears all other fields.
This inadvertently disables SD card-detect (IIC2_PMUX) and some GPIOs
(SDHC1_DIR_PMUX):
LX2162-CF RCWSR12: 0b0000100000000000 0000000000000110
IIC2_PMUX ||| ||| || | ||| |||XXX : I2C/GPIO/CD-WP
SDHC1_DIR_PMUX XXX ||| || | ||| ||| : SDHC/GPIO/SPI
Reverting the commit in question was considered but bus recovery is an
important feature.
Instead add pinmux nodes for those pins that were unintentionally
reconfigured on SolidRun LX2160A Clearfog-CX and LX2162A Clearfog
boards.

Provide addons for:
1. Reconfigure UART A from RS232 to RS485.
2. Reconfigure UART B from RS232 to RS485.
3. Configure DSI Connector for Winstar WJ70N3TYJHMNG0 Panel.

- 1x LVDS Display Connector
- 1x DSI Display Connector
- GPIO header
- 2x RS232/RS485 ports (configurable)
- 2x CAN
In addition there is a board-to-board expansion connector to support
custom daughter boards with access to SPI, a range of GPIOs and -
notably - CAN and UART. Both 2x CAN and 2x UART can be muxed either
to this b2b connector, or a terminal block connector on the base board.
The routing choice for UART and CAN is expressed through gpio
mux-controllers in DT and can be changed by applying dtb overlays.

The SOM does not provide any USB connectors and carrier boards may

While moving the nodes, align the Symphony USB description with the
