* The PIN_PULL[UP|DWN]_[EN|DIS]() functions used to exist as macros in previous SDK versions.

|
* Unfortunately, however, they do not work for some GPIOs on the ESP32 chip, which needs pullups

* and -downs turned on and off through RTC registers. The functions still exist for compatibility
|
|
* with older code, but are marked as deprecated in order to generate a warning.

* Please replace them in this fashion: (make sure to include driver/gpio.h as well)
|

* PIN_PULLUP_EN(GPIO_PIN_MUX_REG[x]) -> gpio_pullup_en(x)
