The v1 on MX23 only gets 16 bits counter, while v2 on MX28 extends the counter to 32 bits. The implementation uses two timers, one for clock_event and another for clocksource. MX28 uses timrot 0 and 1, while MX23 uses 0 and 2. Signed-off-by: Shawn Guo <shawn.guo@freescale.com> Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
