rampis: HLK-RM04 - Setup I2C as GPIO
The I2C function of the RT5350 SoC on the HLK-RM04 is used for GPIO1 and GPIO2.
Take note that the I2C_SD pin is GPIO1 on the RT5350 and is exposed on the HLK-RM04 as GPIO0
Likewise the I2C_SCLK pin is GPIO2 on the RT5350 and is exposed on the HLK-RM04 as GPIO1
group mode 1 mode 2 hlk-rm04 pin & export
i2c i2c_sd gpio1 (pin 8, hlk-rm04:gpio0)
i2c i2c_sclk gpio2 (pin 9, hlk-rm04:gpio1)
