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, Nikolaus
