* clocksource: convert MXS timrotv2 to 32-bit down counting clocksourceRussell King2011-05-231-13/+7
| | | | | | | | | Convert the MXS timrotv2 32-bit down counting clocksource to the generic clocksource infrastructure. Cc: Sascha Hauer <kernel@pengutronix.de> Acked-by: Shawn Guo <shawn.guo@freescale.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: mxs: Add timer supportShawn Guo2010-12-201-0/+296
There are 2 versions of the timrot on Freescale MXS-based SoCs. 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.
