7 title: Netronix Embedded Controller
10 - Jonathan Neuschäfer <j.neuschaefer@gmx.net>
13 This EC is found in e-book readers of multiple brands (e.g. Kobo, Tolino), and
14 is typically implemented as a TI MSP430 microcontroller.

31 The EC can signal interrupts via a GPIO line
36 Number of cells in a PWM specifier.
38 The following PWM channels are supported:
