The GPIO buffer load capacity is not specified in units of current. It is specified in terms of buffer drive strength or output impedance. For example, refer to the Section 4.8.1 "GPIO Output Buffer Impedance" of the i.MX 6Dual/6Quad  Applications Processors for Consumer Products Data Sheet Rev.4 document, available on the processor's Documentation web page:

http://www.nxp.com/products/microcontrollers-and-processors/arm-processors/i.mx-applications-process...

Also, the total load current and power dissipation should be taken into account when calculating the GPIO power budget.


Have a great day,
