| * ARM: mxs: use apbx bus clock to drive the timers on timrotv2Torben Hohn2013-02-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | timer resolution of ~32us is pretty low. v2 has 32bits resolution, so we have quite some headroom, and can use the 24MHz clock. v1 has only 16bits, so we only increase v2. So we just exchange the timrot clock in imx28. On imx23 we have timrotv1 and everything stays the same.

| | | | | | | | | | | | | | | | | | | | | | | | | | It really becomes a maintenance issue that every time a device needs to look up (clk_get) a clock we have to patch kernel clock file to call clk_register_clkdev for that clock. Since clock DT support which is meant to resolve clock lookup in device tree is in place, the patch moves imx23 client devices' clock lookup over to device tree, so that any new lookup to be added at later time can just get done in DT instead of kernel.
