2007-01-24 | [ARM] 4092/1: i.MX/MX1 CPU Frequency scaling latency definition | Pavel Pisa | |
The transition latency has to be defined and reasonably small to allow on-demand and conservative governors. The value has been defined according to manual. The imx_set_target() protected against seen out of range requests now.

2006-12-13 | [ARM] 3992/1: i.MX/MX1 CPU Frequency scaling support | Pavel Pisa | |
Support to change MX1 CPU frequency at runtime. Tested on PiKRON's PiMX1 board and seems to be fully stable up to 200 MHz end even as low as 8 MHz. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> |
