If anyone has any objections, please let me know. ------------------ From: Dmitry Baryshkov [ Upstream commit 7f492d48f08207e4ee23edc926b11de9f720aa61 ] If cluster domain idle state is enabled on the RB1, the board becomes significantly less responsive. Under certain circumstances (if some of the devices are disabled in kernel config) the board can even lock up. It seems this is caused by the MPM not updating wakeup timer during CPU idle (in the same way the RPMh updates it when cluster idle state is entered). Disable cluster domain idle for the RB1 board until MPM driver is fixed to cooperate with the CPU idle states.
