++	 * with stacked INTCs. In particular problem happens if its master INTC
++	 * not yet instantiated. See discussion here -
++	 * https://lkml.org/lkml/2015/3/4/755
++	 *
++	 * So setup the first gpio block as a passive pass thru and hide it from
++	 * DT hardware topology - connect intc directly to cpu intc
++	 * The GPIO "wire" needs to be init nevertheless (here)
++	 *
++	 * One side adv is that peripheral interrupt handling avoids one nested
++	 * intc ISR hop
++	 *
++	 * According to HSDK User's Manual [1], "Table 2 Interrupt Mapping"
++	 * we have the following GPIO input lines used as sources of interrupt:
++	 * - GPIO[0] - Bluetooth interrupt of RS9113 module
++	 * - GPIO[2] - HAPS interrupt (on HapsTrak 3 connector)
++	 * - GPIO[3] - Audio codec (MAX9880A) interrupt
++	 * - GPIO[8-23] - Available on Arduino and PMOD_x headers
++	 * For now there's no use of Arduino and PMOD_x headers in Linux
++	 * use-case so we only enable lines 0, 2 and 3.
