# CP Plus CP-UNC-TA21L2C (Goke gk7205v200, SmartSens SC223A) board pinmux.
#
# Runs after S70vendor (load_goke), overriding the SDK board=demo defaults
# for this board's actual wiring:
#  - the SC223A i2c is on hardware I2C0 routed to the VI-RAW pads
#    (0x60/0x64 func2), not the default mipi-sensor pads (0x30/0x34 func1);
#  - sensor reset/enable is GPIO8_7 (SENSOR_RSTN, func2);
#  - the SC223A needs a 27 MHz MCLK (div6 = 0x19); the SDK default 0x11
#    (div4) is wrong, so the sensor never ACKs without this.
# (load_goke already muxes SENSOR_CLK 0x112c0028 to func1, so it is left as-is.)
