meanwhile i found to change gpio mode:

	(*&gpiomode = readl((void *)(0xb0000060)));
	if ((gpiomode & 0x100000) == 0) {
		gpiomode &= (~0x100000);
		writel(gpiomode, (void *)(0xb0000060));
	
		rt2x00_info(rt2x00dev, "Change as Normal Mode(0x%lx)\n", gpiomode);
		(*&gpiomode = readl((void *)(0xb0000060)));
		rt2x00_info(rt2x00dev, "After Change GPIO_MODE value is 0x%lx\n", gpiomode);
	}

comp. reg has to be 0, opposed to mtk driver where it's 0x100000 representing PA gpio mode which means rt2x00 doesn't run the PA in gpio mode. mini shows the 0x48371d value with PA enabled in DTS code and 0x58371d without it enabled.
