GTA04 has a W2SG0004/84 connected to UART2 of the OMAP3
processor. A GPIO can pulse the on/off toggle switch.

The VSIM regulator is used to power on/off the LNA of an external
active GPS antenna so that a driver can turn the LNA off if GPS is
not needed to save battery energy.

};
How about move the comment above the node to avoid long lines?
Or just change it to gpio_145 for the comment as the property
is already enable-gpios?

Done so that it will be included in next version.

BR and thanks,
