This adjusts the point at which certain APIs will switch from
using a stack allocated buffer to a dynamically allocated buffer.
You shouldn't need to change this unless you really need to
optimize either stack space or performance. Change this carefully
since setting an incorrect value could cause stack corruption.

These checks help ensure that GPIOs have been properly initialized
before they are used, and that sleeping calls are not made from

There are 7 GPIOs and few sensor related GPIOs supported
by the TPS68470. While the 7 GPIOs can be configured as

are "output only" GPIOs.
This driver config is bool, as the GPIO functionality
of the TPS68470 must be available before dependent
