Vendor: Espressif Systems

Description

Espressif's general-purpose Timers.
Each Timer is part of a Timer Group and the number of available Timers
is SoC-dependent.

As as example, ESP32 has 4 Timers available, which are split in two
different groups (TIM0_G0, TIM1_G0, TIM0_G1 and TIM1_G1).

In order to use one of the available timers on your application add
a <board>.overlay file with contents as below

  &timer0 {
          status = "okay";
          prescaler = <10>;
  };

From the above, setting 'status' is required while the prescaler is
optional. Check below for more information on the prescaler.
