This patch renumbers the (virtual) GPIO line numbering to have all
irq-capable gpio lines <= EP93XX_GPIO_LINE_MAX_IRQ by swapping the
port f range with the port c range; This simplifies code such as
#define IRQ_EP93XX_GPIO(x) (64 + (((x) + (((x) >> 2) & 8)) & 0x1f))
or
if (line >= 0 && line < 16) {
/* Port A/B */
} else if (line >= 40 && line < 48) {
/* Port F */
}
considerably; in addition to the renumbering this patch also
introduces macro constants EP93XX_GPIO_LINE_MAX_IRQ and
EP93XX_GPIO_LINE_MAX, and replaces most magic numbers by those and
invocations of gpio_to_irq()/irq_to_gpio().
