Gunar Schorcht	bb51fbb7ec	cpu/esp32: fix GPIO32 and GPIO 33 as I2C pins ... GPIO32 and GPIO33 are used during boot to start an 32.768 kHz XTAL if it is connected to these GPIOs. If the 32.768 kHz XTAL is not connected, these pins can be used digital IO. However, the 32.678 kHz XTAL has to be disabled explicitly in this case. Furthermore, the handling of GPIOs greater than GPIO31 had to be fixed in I2C software implementation.	2020-04-17 18:46:15 +02:00
