[PATCHv2 6/7] ARM: OMAP3 PM: Remove IO Daisychain control from cpuidle

Fri Oct 7 13:47:50 EDT 2011


As IO Daisy chain sequence is triggered via hwmod mux, there is no need to
control it from cpuidle path for OMAP3.

Also as omap3_disable_io_chain is no longer being used, just remove the function.
