		* - On Salvator-X[S], GP6_3[01] are connected to ADV7482 as irq pins
		* (when SW31 is the default setting on Salvator-XS).
		* - If SW31 is the default setting, you cannot use USB2.0 ch3 on
		* r8a7795 with Salvator-XS.
		* Hence the SW31 setting must be changed like 2) below.
		* 1) Default setting of SW31: ON-ON-OFF-OFF-OFF-OFF:
		* - Connect GP6_3[01] to ADV7842.
		* 2) Changed setting of SW31: OFF-OFF-ON-ON-ON-ON:
		* - Connect GP6_3[01] to BD082065 (USB2.0 ch3's host power).
		* - Connect GP6_{04,21} to ADV7842.
