ESP32-C6 Pin Mux Will Not Allow Simultaneous I2C and SPI Interfaces

There appears to be no way to have an I2C bus and a SPI bus at the same time because pin 12 is used for LP_I2C_SDA/FSPICLK and pin 13 is used for LP_I2C_SDA/FSPID. That seems to be a real issue. I have many systems that use both SPI and I2C. Am I missing something?

You can do pin remapping.
